General DescriptionThe MAX13080E–MAX13089E +5.0V, ±15kV ESD-protect-ed, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry,guaranteeing a logic-high receiver output when receiver inputs are open or shorted. The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance). The MAX13080E–MAX13089E include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also feature slew-rate-limited drivers but allow transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088E driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E slew rate is pin selectable for 250kbps,500kbps, and 16Mbps.The MAX13082E/MAX13085E/MAX13088E are intended for half-duplex communications, and the MAX13080E/MAX13081E/MAX13083E/MAX13084E/MAX13086E/MAX13087E are intended for full-duplex communica-tions. The MAX13089E is selectable for half-duplex or full-duplex operation. It also features independently programmable receiver and transmitter output phase through separate pins.The MAX13080E–MAX13089E transceivers draw 1.2mA of supply current when unloaded or when fully loaded with the drivers disabled. All devices have a 1/8-unit load receiver input impedance, allowing up to 256transceivers on the bus.The MAX13080E/MAX13083E/MAX13086E/MAX13089E are available in 14-pin PDIP and 14-pin SO packages.The MAX13081E/MAX13082E/MAX13084E/MAX13085E/MAX13087E/MAX13088E are available in 8-pin PDIP and 8-pin SO packages.

These devices feature fail-safe circuit-ry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all dri-vers disabled (see the Fail-Safe section). The MAX13080E/MAX13082E/MAX13083E/MAX13085E/ MAX13086E/MAX13088E/MAX13089E also feature a hot-swap capability allowing line insertion without erroneous data transfer (see the Hot Swap Capability section). The MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 250kbps. The MAX13083E/MAX13084E/MAX13085E also offer slew-rate limits allowing transmit speeds up to 500kbps. The MAX13086E/MAX13087E/MAX13088Es’ driver slew rates are not limited, making transmit speeds up to 16Mbps possible. The MAX13089E’s slew rate is selectable between 250kbps, 500kbps, and 16Mbps by driving a selector pin with a three-state driver.The MAX13082E/MAX13085E/MAX13088E are half-duplex transceivers, while the MAX13080E/MAX13081E/ MAX13083E/MAX13084E/MAX13086E/MAX13087E are full-duplex transceivers. The MAX13089E is selectable between half- and full-duplex communication by driving a selector pin (H/F) high or low, respectively.All devices operate from a single +5.0V supply. Drivers are output short-circuit current limited. Thermal-shutdown circuitry protects drivers against excessive power dissi-pation. When activated, the thermal-shutdown circuitry places the driver outputs into a high-impedance state.Receiver Input Filtering The receivers of the MAX13080E–MAX13085E, and the MAX13089E when operating in 250kbps or 500kbps mode, incorporate input filtering in addition to input hysteresis. This filtering enhances noise immunity with differential signals that have very slow rise and fall times. Receiver propagation delay increases by 25% due to this filtering.Fail-Safe The MAX13080E family guarantees a logic-high receiver output when the receiver inputs are shorted or open, or when they are connected to a terminated transmission line with all drivers disabled. This is done by setting the receiver input threshold between -50mV and -200mV. If the differential receiver input voltage (A - B) is greater than or equal to -50mV, RO is logic-high. If (A - B) is less than or equal to -200mV, RO is logic-low. In the case of a terminated bus with all transmitters disabled, the receiv-er’s differential input voltage is pulled to 0V by the termi-nation. With the receiver thresholds of the MAX13080E family, this results in a logic-high with a 50mV minimumnoise margin. Unlike previous fail-safe devices, the-50mV to -200mV threshold complies with the ±200mVEIA/TIA-485 standard.Hot-Swap Capability (Except MAX13081E/MAX13084E/MAX13087E)Hot-Swap InputsWhen circuit boards are inserted into a hot or powered backplane, differential disturbances to the data buscan lead to data errors. Upon initial circuit board inser-tion, the data communication processor undergoes itsown power-up sequence. During this period, the processor’s logic-output drivers are high impedanceand are unable to drive the DE and RE inputs of these devices to a defined logic level. Leakage currents up to±10µA from the high-impedance state of the proces-sor’s logic drivers could cause standard CMOS enableinputs of a transceiver to drift to an incorrect logic level. Additionally, parasitic circuit board capacitance couldcause coupling of V CC or GND to the enable inputs. Without the hot-swap capability, these factors could improperly enable the transceiver’s driver or receiver.When V CC rises, an internal pulldown circuit holds DElow and RE high. After the initial power-up sequence,the pulldown circuit becomes transparent, resetting thehot-swap tolerable input.Hot-Swap Input CircuitryThe enable inputs feature hot-swap capability. At theinput there are two NMOS devices, M1 and M2 (Figure 9). When V CC ramps from zero, an internal 7µstimer turns on M2 and sets the SR latch, which alsoturns on M1. Transistors M2, a 1.5mA current sink, andM1, a 500µA current sink, pull DE to GND through a5kΩresistor. M2 is designed to pull DE to the disabledstate against an external parasitic capacitance up to100pF that can drive DE high. After 7µs, the timer deactivates M2 while M1 remains on, holding DE low against three-state leakages that can drive DE high. M1 remains on until an external source overcomes the required input current. At this time, the SR latch resetsand M1 turns off. When M1 turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CCdrops below 1V, the hot-swap input is reset.For RE there is a complementary circuit employing two PMOS devices pulling RE to V CC. MAX13080E–MAX13089E+5.0V, ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversM A X 13080E –M A X 13089EMAX13089E ProgrammingThe MAX13089E has several programmable operating modes. Transmitter rise and fall times are programma-ble, resulting in maximum data rates of 250kbps,500kbps, and 16Mbps. To select the desired data rate,drive SRL to one of three possible states by using a three-state driver: V CC , GND, or unconnected. F or 250kbps operation, set the three-state device in high-impedance mode or leave SRL unconnected. F or 500kbps operation, drive SRL high or connect it to V CC .F or 16Mbps operation, drive SRL low or connect it to GND. SRL can be changed during operation without interrupting data communications.Occasionally, twisted-pair lines are connected backward from normal orientation. The MAX13089E has two pins that invert the phase of the driver and the receiver to cor-rect this problem. F or normal operation, drive TXP and RXP low, connect them to ground, or leave them uncon-nected (internal pulldown). To invert the driver phase,drive TXP high or connect it to V CC . To invert the receiver phase, drive RXP high or connect it to V CC . Note that the receiver threshold is positive when RXP is high.The MAX13089E can operate in full- or half-duplex mode. Drive H/F low, leave it unconnected (internal pulldown), or connect it to GND for full-duplex opera-tion. Drive H/F high for half-duplex operation. In full-duplex mode, the pin configuration of the driver and receiver is the same as that of a MAX13080E. In half-duplex mode, the receiver inputs are internally connect-ed to the driver outputs through a resistor-divider. This effectively changes the function of the device’s outputs.Y becomes the noninverting driver output and receiver input, Z becomes the inverting driver output and receiver input. In half-duplex mode, A and B are still connected to ground through an internal resistor-divider but they are not internally connected to the receiver.±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The driver outputs and receiver inputs of the MAX13080E family of devices have extra protection against static electricity. Maxim’s engineers have devel-oped state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD struc-tures withstand high ESD in all states: normal operation,shutdown, and powered down. After an ESD event, the MAX13080E–MAX13089E keep working without latchup or damage.ESD protection can be tested in various ways. The transmitter outputs and receiver inputs of the MAX13080E–MAX13089E are characterized for protec-tion to the following limits:•±15kV using the Human Body Model•±6kV using the Contact Discharge method specified in IEC 61000-4-2ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 10a shows the Human Body Model, and Figure 10b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.IEC 61000-4-2The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. However, it does not specifically refer to integrated circuits. The MAX13080E family of devices helps you design equip-ment to meet IEC 61000-4-2, without the need for addi-tional ESD-protection components.+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversThe major difference between tests done using the Human Body Model and IEC 61000-4-2 is higher peak current in IEC 61000-4-2 because series resistance is lower in the IEC 61000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 61000-4-2 is generally lower than that measured using the Human Body Model. Figure 10c shows the IEC 61000-4-2 model, and Figure 10d shows the current waveform for IEC 61000-4-2 ESD Contact Discharge test.Machine Model The machine model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. The objective is to emulate the stress caused when I/O pins are contacted by handling equipment during test and assembly. Of course, all pins require this protection, not just RS-485 inputs and outputs.Applications Information256 Transceivers on the BusThe standard RS-485 receiver input impedance is 12kΩ(1-unit load), and the standard driver can drive up to 32-unit loads. The MAX13080E family of transceivers has a1/8-unit load receiver input impedance (96kΩ), allowingup to 256 transceivers to be connected in parallel on one communication line. Any combination of these devices,as well as other RS-485 transceivers with a total of 32-unit loads or fewer, can be connected to the line.Reduced EMI and ReflectionsThe MAX13080E/MAX13081E/MAX13082E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission up to250kbps. The MAX13083E/MAX13084E/MAX13085Eoffer higher driver output slew-rate limits, allowing transmit speeds up to 500kbps. The MAX13089E withSRL = V CC or unconnected are slew-rate limited. WithSRL unconnected, the MAX13089E error-free data transmission is up to 250kbps. With SRL connected toV CC,the data transmit speeds up to 500kbps.

In shutdown, the devices typically draw only 2.8µA of supply current.RE and DE can be driven simultaneously; the devices are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 700ns, the devices are guaranteed to enter shutdown.Enable times t ZH and t ZL (see the Switching Characteristics section) assume the devices were not in a low-power shutdown state. Enable times t ZH(SHDN)and t ZL(SHDN)assume the devices were in shutdown state. It takes drivers and receivers longer to become enabled from low-power shutdown mode (t ZH(SHDN), t ZL(SHDN))than from driver/receiver-disable mode (t ZH , t ZL ).Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or by bus contention.The first, a foldback current limit on the output stage,provides immediate protection against short circuits over the whole common-mode voltage range (see the Typical Operating Characteristics ). The second, a thermal-shut-down circuit, forces the driver outputs into a high-imped-ance state if the die temperature exceeds +175°C (typ).Line LengthThe RS-485/RS-422 standard covers line lengths up to 4000ft. F or line lengths greater than 4000ft, use the repeater application shown in Figure 11.Typical ApplicationsThe MAX13082E/MAX13085E/MAX13088E/MAX13089E transceivers are designed for bidirectional data commu-nications on multipoint bus transmission lines. F igures 12 and 13 show typical network applications circuits. To minimize reflections, terminate the line at both ends in its characteristic impedance, and keep stub lengths off the main line as short as possible. The slew-rate-lim-ited MAX13082E/MAX13085E and the two modes of the MAX13089E are more tolerant of imperfect termination.Chip InformationTRANSISTOR COUNT: 1228PROCESS: BiCMOS+5.0V , ±15kV ESD-Protected, Fail-Safe, Hot-Swap, RS-485/RS-422 TransceiversFigure 11.

1.5µA IQ, Step-Up DC-DC Converters in Thin SOT23-5
General Description
The MAX1722/MAX1723/MAX1724 compact, high-efficiency, step-up DC-DC converters are available in tiny, 5pin thin SOT23 packages. They feature an extremely low 1.5µA quiescent supply current to ensure the highest possible light-load efficiency. Optimized for operation from one to two alkaline or nickel-metal-hydride (NiMH) cells, or a single Li+ cell, these devices are ideal for applications where extremely low quiescent current and ultra-small size are critical. Built-in synchronous rectification significantly improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode. All three devices feature a 0.5Ω N-channel power switch. The MAX1722/ MAX1724 also feature proprietary noise-reduction circuitry, which suppresses electromagnetic interference (EMI) caused by the inductor in many step-up applications. The family offers different combinations of fixed or adjustable outputs, shutdown, and EMI reduction (see Selector Guide). o o o o o o o o o o o

The MAX5481/MAX5482 are 3-terminal voltage-dividers and the MAX5483/MAX5484are 2-terminal variable resistors.The MAX5481–MAX5484 feature an internal, non-volatile, electrically erasable programmable read-only memory (EEPROM) that stores the wiper position for ini-tialization during power-up. The 3-wire SPI-compatible serial interface allows communication at data rates up to 7MHz. A pin-selectable up/down digital interface is also available.The MAX5481–MAX5484 are ideal for applications requiring digitally controlled potentiometers. Two end-to-end resistance values are available (10k Ωand 50k Ω) in a voltage-divider or a variable-resistor configuration (see the Selector G uide ). The nominal resistor temperature coefficient is 35ppm/°C end-to-end, and only 5ppm/°C ratiometric, making these devices ideal for applications requiring low-temperature-coefficient voltage-dividers,such as low-drift, programmable gain-amplifiers.The MAX5481–MAX5484 operate with either a +2.7V to +5.25V single power supply or ±2.5V dual power sup-plies. These devices consume 400µA (max) of supply current when writing data to the nonvolatile memory and 1.0µA (max) of standby supply current. The MAX5481–MAX5484 are available in a space-saving (3mm x 3mm), 16-pin TQFN, or a 14-pin TSSOP pack-age and are specified over the extended (-40°C to +85°C) temperature range.ApplicationsFeatures♦1024 Tap Positions♦Power-On Recall of Wiper Position from Nonvolatile Memory♦16-Pin (3mm x 3mm x 0.8mm) TQFN or 14-Pin TSSOP Package♦35ppm/°C End-to-End Resistance Temperature Coefficient♦5ppm/°C Ratiometric Temperature Coefficient ♦10kΩand 50kΩEnd-to-End Resistor Values♦Pin-Selectable SPI-Compatible Serial Interface or Up/Down Digital Interface ♦1µA (max) Standby Current♦Single +2.7V to +5.25V Supply Operation ♦Dual ±2.5V Supply OperationMAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometers________________________________________________________________Maxim Integrated Products1Ordering InformationPin Configurations19-3708; Rev 5; 4/10For pricing delivery, and ordering information please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .Selector Guide appears at end of data sheet.SPI is a trademark of Motorola, Inc.temperature range.+Denotes a lead(Pb)-free/RoHS-compliant package.*EP = Exposed pad.Ordering Information continued at end of data sheet.Gain and Offset AdjustmentLCD Contrast Adjustment Pressure SensorsLow-Drift Programmable Gain AmplifiersMechanical Potentiometer ReplacementM A X 5481–M A X 548410-Bit, Nonvolatile, Linear-Taper Digital PotentiometersABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

programmable voltage-dividers and the MAX5483/MAX5484 variable resistors feature 1024 tap points (10-bit resolution) (see the Functional Diagrams ). These devices consist of multi-ple strings of equal resistor segments with a wiper con-tact that moves among the 1024 points through a pin-selectable 3-wire SPI-compatible serial interface or up/down interface. The MAX5481/MAX5483 provide a total end-to-end resistance of 10k Ω, and the MAX5482/MAX5484 have an end-to-end resistance of 50k Ω. The MAX5481/MAX5482 allow access to the high, low, and wiper terminals for a standard voltage-divider configuration.MAX5481/MAX5482 ProgrammableVoltage-DividersThe MAX5481/MAX5482 programmable voltage-dividers provide a weighted average of the voltage between the H and L inputs at the W output. Both devices feature 10-bit resolution and provide up to 1024 tap points between the H and L voltages. Ideally,the V L voltage occurs at the wiper terminal (W) when all data bits are zero and the V H voltage occurs at the wiper terminal when all data bits are one. The step size (1 LSB) voltage is equal to the voltage applied across terminals H and L divided by 210. Calculate the wiper voltage V Was follows:Functional Diagrams (continued)MAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometerswhere D is the decimal equivalent of the 10 data bits writ-ten (0 to 1023), V HL is the voltage difference between the H and L terminals:The MAX5481 includes a total end-to-end resistance value of 10k Ωwhile the MAX5482 features an end-to-end resistance value of 50k Ω. These devices are not intended to be used as a variable resistor . Wiper cur-rent creates a nonlinear voltage drop in series with the wiper. To ensure temperature drift remains within speci-fications, do not pull current through the voltage-divider wiper. Connect the wiper to a high-impedance node.Figures 1 and 2 show the behavior of the MAX5481’s resistance from W to H and from W to L. This does not apply to the variable-resistor devicesMAX5483/MAX5484 Variable ResistorsThe MAX5483/MAX5484 provide a programmable resistance between W and L. The MAX5483 features a total end-to-end resistance value of 10k Ω, while the MAX5484 provides an end-to-end resistance value of 50k Ω. The programmable resolution of this resistance is equal to the nominal end-to-end resistance divided by 1024 (10-bit resolution). For example, each nominal segment resistance is 9.8Ωand 48.8Ωfor the MAX5483and the MAX5484, respectively.wiper position from the 1024 possible positions, result-ing in 1024 values for the resistance from W to L.Calculate the resistance from W to L (R WL ) by using the where D is decimal equivalent of the 10 data bits writ-ten, R W-L is the nominal end-to-end resistance, and R Z is the zero-scale error. Table 1 shows the values of R WL at selected codes for the MAX5483/MAX5484.Digital InterfaceConfigure the MAX5481–MAX5484 by a pin-selectable,3-wire, SPI-compatible serial data interface or an up/down interface. Drive SPI/UD high to select the 3-wire SPI-compatible interface. Pull SPI/UD low to select the up/down interface.V FSE V andV ZSE V FSE HL ZSE HL =⎡⎣⎢⎤⎦⎥=⎡⎣⎢⎤⎦⎥10241024,Figure 1.

This write-only interface contains three inputs: chip select (CS ), data in (DIN(U/D )), and data clock (SCLK(INC )). Drive CS low to load the data at DIN(U/D ) synchronously into the shift register on each SCLK(INC ) rising edge.The WRITE command (C1, C0 = 00) requires 24 clock cycles to transfer the command and data (Figure 4a).The COPY commands (C1, C0 = 10 or 11) use either eight clock cycles to transfer the command bits (Figure 4b) or 24 clock cycles with the last 16 data bits disre-garded by the device.After loading the data into the shift register, drive CS high to latch the data into the appropriate control regis-ter. Keep CS low during the entire serial data stream to avoid corruption of the data. Table 2 shows the com-mand decoding.Write Wiper RegisterData written to this register (C1, C0 = 00) controls the wiper position. The 10 data bits (D9–D0) indicate the position of the wiper. For example, if DIN(U/D ) = 00 00000000, the wiper moves to the position closest to L. If DIN(U/D ) = 11 1111 1111, the wiper moves closest to H.This command writes data to the volatile random access memory (RAM), leaving the NV register unchanged. When the device powers up, the data stored in the NV register transfers to the wiper register,moving the wiper to the stored position. Figure 5 shows how to write data to the wiper register.Table 2.

Write Wiper Register OperationM A X 5481–M A X 548410-Bit, Nonvolatile, Linear-Taper Digital Potentiometers Copy Wiper Register to NV RegisterThe copy wiper register to NV register command (C1,C0 = 10) stores the current position of the wiper to the NV register for use at power-up. Figure 6 shows how to copy data from wiper register to NV register. The oper-ation takes up to 12ms (max) after CS goes high to complete and no other operation should be performed until completion.Copy NV Register to Wiper RegisterThe copy NV register to wiper register (C1, C0 = 11)restores the wiper position to the current value stored in the NV register. Figure 7 shows how to copy data from the NV register to the wiper register.Digital Up/Down InterfaceFigure 8 illustrates an up/down serial-interface timing diagram. In digital up/down interface mode (SPI/UD =0), the logic inputs CS , DIN(U/D ), and SCLK(INC ) con-trol the wiper position and store it in nonvolatile memory (see Table 3). The chip-select (CS ) input enables the serial interface when low and disables the interface when high. The position of the wiper is stored in the nonvolatile register when CS transitions from low to high while SCLK(INC ) is high.When the serial interface is active (CS low), a high-to-low (falling edge) transition on SCLK(INC ) increments or decrements the internal 10-bit counter depending on the state of DIN(U/D ). If DIN(U/D ) is high, the wiper increments. If DIN(U/D ) is low, the wiper decrements.The device stores the value of the wiper position in the nonvolatile memory when CS transitions from low to high while SCLK(INC ) is high. The host system can disablethe serial interface and deselect the device without stor-ing the latest wiper position in the nonvolatile memory by keeping SCLK(INC ) low while taking CS high.Upon power-up, the MAX5481–MAX5484 load the value of nonvolatile memory into the wiper register, and set the wiper position to the value last stored.Figure 6.

Copy NV Register to Wiper Register OperationMAX5481–MAX548410-Bit, Nonvolatile, Linear-Taper DigitalPotentiometersStandby ModeThe MAX5481–MAX5484 feature a low-power standby mode. When the device is not being programmed, it enters into standby mode and supply current drops to 0.5µA (typ).Nonvolatile MemoryThe internal EEPROM consists of a nonvolatile register that retains the last value stored prior to power-down.The nonvolatile register is programmed to midscale at the factory. The nonvolatile memory is guaranteed for 50 years of wiper data retention and up to 200,000wiper write cycles.Power-UpUpon power-up, the MAX5481–MAX5484 load the data stored in the nonvolatile wiper register into the volatile wiper register, updating the wiper position with the data stored in the nonvolatile wiper register.Applications InformationThe MAX5481–MAX5484 are ideal for circuits requiring digitally controlled adjustable resistance, such as LCD contrast control (where voltage biasing adjusts the dis-play contrast), or programmable filters with adjustable gain and/or cutoff frequency.Positive LCD Bias ControlFigures 9 and 10 show an application where a voltage-divider or a variable resistor is used to make an adjustable, positive LCD-bias voltage. The op amp pro-vides buffering and gain to the voltage-divider network made by the programmable voltage-divider (Figure 9) or to a fixed resistor and a variable resistor (see Figure 10).Programmable Gain and Offset AdjustmentFigure 11 shows an application where a voltage-divider and a variable resistor are used to make a programma-ble gain and offset adjustment.Figure 8.

MAX5921A Evaluation Kit
General Description
The MAX5921A evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that provides current-limiting and multilevel fault protection using the MAX5921A hot-swap controller. The EV kit demonstrates the autoretry, configurable input undervoltage, overvoltage, and overcurrent monitoring features of the MAX5921A. The MAX5921A controls an external N-channel MOSFET to provide load-current regulation. The EV kit circuit undervoltage and overvoltage thresholds are configured to -32V and -80V, respectively, which makes the EV kit well suited for -48V telecom systems. The input operating voltage range is -20V to -80V (-48V rail systems). The EV kit is designed to withstand -100V input transients. The current-limiting threshold is configured for 1.8A output current. The EV kit can also be used to evaluate different versions of the MAX5920, MAX5921, or MAX5939 hotswap controllers after removing the MAX5921A. The MAX5920A/B are pin- and function-compatible with the LT4250 hot-swap controllers and pin-compatible with LT1640. Warning: The MAX5921A EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on equipment connected to it. Users who power up this EV kit or power the sources connected to it must be careful to follow safety procedures appropriate to working with high-voltage electrical equipment. Under severe fault or failure conditions, this EV kit may dissipate large amounts of power, which could result in the mechanical ejection of a component or of component debris at high velocity. Operate this kit with care to avoid possible personal injury. The EV kit user should not probe the circuit with an oscilloscope probe and ground clip unless they have “high-voltage, hot-swap experience.”

MAX5945EVKIT中文资料

General DescriptionThe MAX5945 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board featuring an Ethernet four-port network power controller circuit for -48V supply rail systems. The MAX5945 IEEE 802.3af-compliant network power controller is available in a 36-pin SSOP package. The circuit includes four n-channel power MOSFETs used to form the main power-sourcing equipment (PSE) circuit on the EV kit. The MAX5945 is used in power-over-ethernet (POE) applications requiring DC power over four Ethernet network ports. The EV kit provides optical isolation for the I 2C-compliant 3-wire interface. The isolated interface connects to a PC parallel port (LPT) through a MAXSMBus interface board. The EV kit can easily be reconfigured for interfacing to a user’s stand-alone microcontroller for isolated or nonisolated operation.The MAX5945 EV kit requires a -32V to -60V power sup-ply (-48V supply rail) capable of supplying 2A or more to the EV kit for powering the power device (PD) through the four 10/100 base-TX Ethernet network ports. The EV kit demonstrates PD discovery, classification, current-limit control and other functions of an IEEE 802.3af-com-pliant PSE. The user must also supply two separate 3.3V power supplies capable of supplying 100mA for the EV kit’s digital logic and 3.3V (V CC ) optically isolated 3-wire interface. The MAXSMBus interface board requires a dedicated 9V power supply capable of supplying 250mA. The +9V power supply is not required for noniso-lated operation.The MAX5945 controls the -48V DC power to each of the four Ethernet network ports by controlling each port’s power MOSFET and sensing current through the respec-tive port’s current-sense resistor. The current is fed to a 10/100 base-TX Voice-over-IP (VoIP) magnetic module at each Ethernet network output port. The MAX5945 EV kit provides a separate independent power channel for each of the four Ethernet network output ports.The EV kit demonstrates the full functionality of the MAX5945 for each power channel such as configurable operational modes, PD detection, PD classification, over-current protection, current foldback, under/overvoltage protection, and AC disconnect monitoring. All of these features are configurable on the EV kit and additional test points for voltage probing and current measurements have been provided.The MAX5945 EV kit software is Windows® 95/98/2000-compatible and provides a user-friendly interface to demonstrate the features of the MAX5945 while provid-ing access to each register at the bit level. The program is menu-driven and offers a graphic interface with control buttons. The program also includes a macro engine to allow automated evaluation and testing of the MAX5945at the system level. The program’s macro output files can be automatically saved.Order the MAX5945EVSYS for a complete PC-based evaluation of the MAX5945.

The EV kit’s PSE circuit usesthe IEEE 802.3af-compliant MAX5945 network power controller, four n-channel power MOSFETs in SOT-223 surface-mount packages, four surface-mount current-sensing resistors and two 10/100 base-TX VoIP mag-netic modules to form the basic portion of a PSE circuit.The MAX5945 EV kit has been designed as an IEEE802.3af-compliant PSE and demonstrates all the required functions such as PD discovery, classification, current-limit control of a connected PD at each Ethernet output port, and DC/AC disconnect detection. The EVkit also has a separate on-board, 100H z sine-wave oscillator circuit for the AC disconnect detection fea-tures. An IBM-compatible PC is used to communicatewith the slave MAX5945 over an I2C-compliant 3-wire interface, optically coupled logic, and a 2-wire to parallel port (LPT) MAXSMBus interface board.The MAX5945 EV kit PSE circuit requires a -32V to -60V power supply (-48V supply rail) capable of supplying2A to the EV kit’s GND and VEE steel banana jacks orPC board pads. Two separate +3.3V power supplies capable of supplying 100mA are also required for theMAX5945 digital logic (VDIG, DGND) and optically iso-lated I2C-compliant 3-wire interface. Note that DGNDand GND are shorted by a PC board trace betweenthe pads of resistor R72.The MAX5945 controls the -48V DC power to each ofthe four 10/100 base-TX Ethernet network output portsby regulating the respective port’s n-channel powerEvaluate: MAX5945MAX5945 Evaluation Kit/Evaluation System _______________________________________________________________________________________5E v a l u a t e : M A X 5945MOSFET and sensing current through the respective port’s current-sense resistor. The current is fed to a 10/100 base-TX VoIP magnetic module connected to the respective Ethernet network output port’s RJ-45jack. An IEEE 802.3af-compliant PD connects to the respective Ethernet network output port on the EV kit.The PD can be located up to 350ft from the EV kit when connected with Category 5 Ethernet cable. The MAX5945 EV kit provides separate and independent power control for each of the four Ethernet network out-put ports. The 10/100 base-TX VoIP magnetic module is decoupled to the EV kit’s chassis ground by system chassis capacitors C19–C22, C24, and C25. The EV kit’s isolated chassis ground (Chassis_GND) PC board pad connects to the network system ground.The MAX5945 EV kit features configurable operational modes, PD detection, PD classification, overcurrent protection, current foldback, under/overvoltage protec-tion, DC and AC disconnect monitoring. The overcur-rent protection can be programmed through software and/or changing current-sense resistors R1–R4 for the desired output port. Each of the four modes of opera-tion (auto, semi, manual, shutdown) can be evaluated after configuring jumper JU6 and configuring the appropriate MAX5945 register (see Table 3). PD detec-tion diodes D1–D4 can be bypassed to reduce power dissipation when AC disconnect monitoring is not required, using jumpers JU15–JU18. Each port’s AC detection circuit resistor-capacitor diode (RCD) net-work can be reconfigured with a jumper also. See Tables 4, 8, and 9 for various AC detection-disconnect and oscillator configurations. Each port features a 600W bidirectional overvoltage transient suppressor diode (D9–D12) and decoupling capacitor (C26–C29)for transient protection at the port.Test points and jumpers have been provided for volt-age probing and current measurements of each chan-nel’s power circuit. Additionally, a 6-pin 0.100in center header is also provided for monitoring the SHDN1,SHDN2, SHDN3, SHDN4, and RESET signals routed to the MAX5945 pins from the respective switch (S1–S5).When using the header signals, caution should be exercised since the DGND and GND are shorted by resistor R72’s PC board shorting trace. Green LEDs near each port’s RJ-45 output jack indicate when the respective port power is turned on.A 100H z oscillator circuit that meets the IEEE 802.3af PSE power interface (PI) parameters for AC disconnect detection is provided by the MAX5945 EV kit. Five ICs make up the 100Hz oscillator circuit, which consists of U5, a programmable Dallas Semiconductor 40MH z EconOscillator/divider squarewave oscillator and a MAX7491 dual universal switched-capacitor filter, U4.Voltage reference source U6 (MAX6106) provides 2.048V for the circuit and level shifts the sine wave’s output. The MAX4599, an SPDT analog switch, and U3,an LMX358 dual-output op amp, provides support func-tions for the oscillator circuit. An external sine-wave oscillator meeting the IEEE 802.3af PSE PI parameters can be connected to the EV kit’s BNC connector (OSC_INPUT) after reconfiguring jumper JU7. The EV kit’s 100H z oscillator circuit can be shut down using jumper JU8 if an external oscillator is used or AC dis-connect detection is not required.The EV kit provides the required optical isolation for the I 2C-compliant 3-wire interface so the MAX5945 can operate as a slave device. The optically isolated inter-face connects to a PC parallel port through a MAXSMBus interface board. The MAXSMBus interface board requires a dedicated 9V power supply capable of supplying 250mA. The EV kit’s I 2C-compliant 2-wire or 3-wire interface can be reconfigured for interfacing to a stand-alone microcontroller for isolated (2-wire) or nonisolated (3-wire) serial operation. Additionally, for stand-alone microcontroller operation, the MAXSMBus interface board and 9V power supply are not required.The optical isolation consists of optocoupler U7, which provides galvanic isolation for the serial interface clock line (SCL) and serial interface input data line signals.Optocoupler U8 provides galvanic isolation for the seri-al output and data line (SDAOUT) and INT signals. The SCL and SDAOUT signals’ 3-wire serial interface are combined on the isolated 2-wire side prior to feeding logic buffer U9. The SCL_IN, SDA, INT _OUT,OPTO_GND and VCC PC board pads are used for a 2-wire isolated stand-alone operation. For nonisolated stand-alone 3-wire operation, jumper JU9 must be reconfigured and then the SCL, SDAIN, SDAOUT, INT ,DGND, and VDIG PC board pads must be connected to the microcontroller circuit. Note that VDIG is at +3.3V, which is required by the EV kit. The OPTO_GND and GND, DGND planes are isolated by the optical couplers. However, when using the EV kit in a non-isolated configuration, caution should be exercised since DGND and GND are shorted by resistor R72’s PC board shorting trace.The MAX5945 slave address is configured by four jumpers (JU1–JU4) and can be configured from 0x40through 0x5F hexadecimal serial address. Global address 0x60 is accepted by the MAX5945 regardless of the jumper settings. Refer to Table 1 and the Address Inputs section in the MAX5945 data sheet for more information on setting the MAX5945 slave address.MAX5945 Evaluation Kit/Evaluation System6_______________________________________________________________________________________Evaluate: MAX5945MAX5945 Evaluation Kit/Evaluation System_______________________________________________________________________________________7*Global address calls.E v a l u a t e : M A X 5945MAX5945 Evaluation Kit/Evaluation System 8_______________________________________________________________________________________Jumper SelectionThe MAX5945 EV kit features several jumpers to recon-figure the EV kit for various PSE configurations and PD requirements. Additionally, jumpers and PC board pads are provided for connecting an external micro-controller.MAX5945 I 2C-Compatible 2-Wire or 3-Wire SlaveAddress SelectionThe MAX5945 EV kit features several 3-pin jumpers (JU1–JU4) to set the slave address of the MAX5945least significant bits (LSB) of the slave address on the I 2C-compatible 2-wire or 3-wire interface. The three most significant bits are set by the MAX5945 to 010.The EV kit’s software automatically sets the LSB for the proper read/write command. Table 1 lists the jumper addressing options.Midspan/Signal-Mode SelectionThe MAX5945 EV kit features a 3-pin jumper (JU5) to set the MAX5945 in midspan or signal mode. Table 2lists the jumper options for the two modes used to detect a valid PD connected to the PSE respective Ethernet network output port. Refer to the MAX5945data sheet for more information on the modes.Operational Modes (Automatic, Shutdown)The MAX5945 EV kit features a 3-pin jumper JU6 to set the MAX5945’s initial startup operational mode. After startup, data sent to the mode register (0x12) reconfig-ure the operational mode of the MAX5945. Table 3 lists the jumper options.AC Disconnect Monitoring Oscillator InputThe MAX5945 EV kit features a 3-pin jumper (JU7) to configure the MAX5945’s oscillator input at the OSC_IN pin. The oscillator is used for AC disconnect monitoring of the PD. Table 4 lists the jumper options for the three oscillator configurations available on the EV kit.Evaluate: MAX5945MAX5945 Evaluation Kit/Evaluation System_______________________________________________________________________________________9100Hz Oscillator ShutdownThe MAX5945 EV kit features a jumper to set the EV kit’s on-board 100H z oscillator modes of operation.Table 5 lists the selectable jumper options to configure the 100Hz oscillator.Stand-Alone Microcontroller Interface(Isolated/Nonisolated)The MAX5945 EV kit features PC board pads and a jumper to interface directly with a microcontroller. The 2 x 5-pin jumper JU9 has shorting connections on the bottom layer that must be cut open to disable the opti-cal coupler interface for nonisolated evaluation. The jumper shorting connections must be in place for evalu-ating an isolated stand-alone microcontroller interface.Table 6 lists the selectable jumper options.MAX5945 PORT DET_, OUT_, GATE_, and SENSE_Pins Signal MeasurementsThe MAX5945 EV kit features jumpers to facilitate cur-rent and voltage measuring at each port’s respective DET_, OUT_, GATE_, and SENSE_ pins on the MAX5945 IC. Several 2 x 3-pin and 2-pin jumpers are used to obtain the desired measurement for each port.Jumpers JU11 and JU23 are provided for port 1,jumpers JU12 and JU24 are provided for port 2,jumpers JU13 and JU25 are provided for port 3, and jumpers JU14 and JU26 are provided for port 4. The jumper pins are shorted by a PC board trace on the bottom layer of the EV kit by default for normal opera-tion. The shorts can be cut open for measurements.See Figure 3, the controller circuit schematic for a spe-cific ports jumper.AC Disconnect Operation (Rectifier Diodes D1–D4)The MAX5945 EV kit features jumpers JU15–JU18 to bypass each port’s respective AC disconnect rectifier diode (D1–D4), thus reducing diode power dissipation when AC disconnect is not required. Jumpers JU15–JU18 are used to bypass the respective port’s rec-tifier diode. Table 7 lists the selectable jumper options for each port.E v a l u a t e : M A X 5945MAX5945 Evaluation Kit/Evaluation System 10______________________________________________________________________________________The MAX5945 EV kit features jumpers JU19–JU22 to bypass the AC detection RC network when AC load dis-connect detection is not needed. The inclusion of this RC network does not affect other circuit parameters. Table 8lists the selectable jumper options to reconfigure each port’s AC detection network. See Table 7 above for bypassing the respective port’s AC disconnect diode.The MAX5945 EV kit includes jumpers JU27–JU30 to disconnect each port’s -48V power independently for connection to an external network interface circuit.Additionally, the respective jumper’s pins can be utilized to measure the voltage or current for the respective port.Table 9 lists the specific jumper for each port. Each jumper is shorted on the bottom layer of the PC board.*See the Bypassing AC Disconnect and the DGND-to-GND Connection (Resistor R72) section.SHDN and RESET Signals The MAX5945 EV kit features four pushbutton switches (S1, S2, S3, S4) to independently shut down each channel’s respective power circuit. A reset pushbutton (S5) is also provided to reset the MAX5945.Header J2 (6-pin 0.100in center header) is available for monitoring the SHDN1, SHDN2, SHDN3, SHDN4, and RESET signals routed to the MAX5945 pins. Digital ground is provided at the header on pin 6. See Table 10, which lists the specific switch and header pin sig-nals that can be interfaced with a ribbon cable or test leads. These signals are not isolated and are refer-enced to DGND on the EV kit.Bypassing AC Disconnect and the DGND-to-GNDConnection (Resistor R72) The AC disconnect detection function requires that the EV kit’s DGND be connected directly to the GND. If the AC disconnect detection function is not required, the PC board trace shorting DGND-to-GND at resistor R72 pads can be cut open. Cutting open the PC board shorting trace at resistor R72 allows DGND to be refer-enced to a voltage potential anywhere from V EE to (V EE + 60V). Additionally, when the PC board trace at R72 is cut open, the appropriate AC detection jumper tables must be set and the OSC_IN pin on the MAX5945 must be floating by removing jumper JU7. See Tables 4, 7, and 8 for the appropriate jumper settings to bypass the AC detection function.Refer to the AC Disconnect M onitoring Oscillator Input sec-tion in the MAX5945 data sheet for additional informa-tion. If the AC disconnect detection function is required again, install a 0Ω±5% 1206 case size surface-mount resistor at R72 pads and set the appropriate jumpers. Detailed Description of Software (Words in bold are user-selectable features in the soft-ware).Software Startup A mouse or the tab key is used to navigate various items on the Main Window. Upon starting the program, the MAX5945 EV kit software starts in the Auto Read state.The software automatically detects the Slave Addressand begins reading the contents of each register in theMAX5945. The register’s contents are placed on the appropriate line of the Register Read tables in binaryand hexadecimal format. If data changes between thenext register read, the updated register hexadecimaldata is displayed in red and blinks four times. The blinkrate can be changed in the View|Red Hex Data BlinkRate menu. The left status bar at the bottom of the main window provides the MAXSMBus interface board status.The center status bar provides the current EV kit and macro engine status.Autoread/Run Macro State ControlsWhen the Auto Read checkbox is checked, the pro-gram continuously updates the main window registersand is operating in the autoread state. In the autoread state, data can be written to the MAX5945 by enteringor selecting the desired data in the Register Addressand Hexadecimal or Binary Data combo boxes. Selecting the Write Byte button writes the combo boxdata to the MAX5945. To perform an immediate register read, enter, or choose the desired Register Address,and choose the Read Byte button. H exadecimal or binary data may be entered into the Hexadecimal or Binary Data combo boxes and then the alternate combo box displays the corresponding number in the respective number base.If the Auto Read check box is unchecked, the pro-gram’s main window displays register data from the last read. To obtain current data, a Read Byte must be per-formed after selecting the appropriate register addressfrom the Register Address combo box. The autoreadstate does not read the clear on read (COR) registers.A macro can be run after loading the file from theFile|Open Macro menu. The opened macro is dis-played in the upper half of the Macro edit box and hasan smb file extension. Selecting the Run button runsthe macro to completion and displays the output in the Macro Script Output edit box field.

General Description The MAX5402 µPoT™digital potentiometer is a 256-tap variable resistor with 10kΩtotal resistance in a tiny 8-pin µMAX package. This device functions as a mechan-ical potentiometer, consisting of a fixed resistor string with a digitally controlled wiper contact. It operates from +2.7V to +5.5V single-supply voltages and uses an ultra-low 0.1µA supply current. This device also pro-vides glitchless switching between resistor taps, as well as a convenient power-on reset (POR) that sets the wiper to the midscale position at power-up. A low 5ppm/°C ratiometric temperature coefficient makes it ideal for applications requiring low drift.The MAX5402 serves well in applications requiring digi-tally controlled resistors, including adjustable voltage references and programmable gain amplifiers (PGAs).A nominal end-to-end resistor temperature coefficient of 35ppm/°C makes this part suitable for use as a variable resistor in applications such as low-tempco adjustable gain and other circuit configurations. This device is guaranteed over the extended industrial temperature range (-40°C to +85°C).________________________Applications Mechanical Potentiometer ReplacementLow-Drift PGAsAdjustable Voltage ReferencesFeatures o Small Footprint, 8-Pin µMAX Packageo Ultra-Low 100nA Supply Currento+2.7V to +5.5V Single-Supply Operationo256 Tap Positionso Low Ratiometric Temperature Coefficient5ppm/°Co Low End-to-End Resistor Temperature Coefficient35ppm/°Co Power-On Reset: Wiper Goes to Midscale(Position 128)o Glitchless Switching Between the Resistor Tapso3-Wire SPI™-Interface Compatibleo10kΩResistor ValueMAX5402 256-Tap, µPoT, Low-Drift, Digital PotentiometerPin Configuration19-1896; Rev 0; 1/01Ordering InformationµPoT is a trademark of Maxim Integrated Products.SPI is a trademark of Motorola, Inc.Maxim Integrated Products1 For price, delivery, and to place orders,please contact Maxim Distribution at 1-888-629-4642, or visit Maxim’s website at .Functional DiagramM A X 5402256-Tap, µPoT, Low-Drift,Digital PotentiometerABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V DD = +5V, V H = V DD , V L = 0, T A = T MIN to T MAX .

The potentiometer wiper (pin W)can be programmed to access any one of the 256 dif-ferent tap points on the resistor string. The MAX5402has an SPI-compatible 3-wire serial data interface to control the wiper tap position. This write-only interface contains three inputs: Chip Select (CS ), Data In (DIN),and Data Clock (SCLK ). When CS is taken low, data from the DIN pin is synchronously loaded into the 8-bit serial shift register on the rising edge of each SCLK pulse (Figure 1). The MSB is shifted in first, as shown in Figure 3. Note that if CS is not kept low during the entire data stream, the data will be corrupted and the devicewill need to be reloaded. After all 8 data bits have been loaded into the shift register, they are latched into the decoder once CS is taken high. The decoder switches the potentiometer wiper to the tap position that corre-sponds to the 8-bit input data. Each resistor cell is 10k Ω/255 or 39.2Ωfor the MAX5402.The MAX5402 features POR circuitry. This sets the wiper to the midscale position at power-up by loading a binary value of 128 into the 8-bit latch. The MAX5402can be used as a variable resistor by connecting pin W to either pin H or L.Figure 1. Serial Interface Timing DiagramFigure 2. Detailed Serial Interface Timing DiagramMAX5402256-Tap, µPoT, Low-Drift,Digital Potentiometer________________________________________________________________________________________7Applications InformationThe MAX5402 is intended for a variety of circuits where accurate, fine-tuned adjustable resistance is required,such as in adjustable voltage or adjustable gain circuit configurations. The MAX5402 is used in either a poten-tiometer divider or a variable resistor configuration.Adjustable Current to Voltage ConverterFigure 4 shows the MAX5402 used with a MAX4250low-noise op amp to precisely tune a current-to-voltage converter. Pins H and W of the MAX5402 are connect-ed to the node between R3 and R2, and pin L is con-nected to ground.Adjustable Gain AmplifierThe MAX5402 is used again with the MAX4250 to make a digitally adjustable gain circuit as shown in Figure 5.The normal feedback resistor is replaced with the MAX5402 in a variable resistor configuration, so that the gain of the circuit can be digitally controlled.Adjustable Voltage ReferenceIn Figure 6, the MAX5402 is shown with the MAX6160to make an adjustable voltage reference. In this circuit,the H pin of the MAX5402 is connected to the OUT pin of the MAX6160, the L pin of the MAX5402 is connect-ed to GND, and the W pin of the MAX5402 is connect-ed to the ADJ pin of the MAX6160. The MAX5402allows precise tuning of the voltage reference output. A low 5ppm/°C ratiometric tempco allows a very stable adjustable voltage overtemperature.Figure 4. I to V ConverterFigure 5.

The gain of the PGA is determined by a 6-bit gain code (GC5–GC0) programmed through the serial-data interface (see Register Map ). Specified performance is achieved when the input is driven differentially.Four power codes (PC1–PC0) allow the PGA to be used with reduced bias current when distortion performance can be relaxed. In addition, for each power code, bias current is automatically reduced with gain code for maximum efficiency.The PGA features a differential Class A output stage capable of driving an +68dBmV OFDMA signal from 5MHz–85MHz or two 96MHz +65dBmV OFDMA signals from 5MHz–204MHz into a 75Ω load. This architecture features a differential output that provides superior even-order distortion performance. This requires that atransformer be used to convert to a single-endedoutput. In transmit-disable mode, the output amplifiers are powered down, resulting in low output noise while maintaining the impedance match.3-Wire Serial Programmable Interface (SPI) and Control RegistersThe MAX3523 includes a user-programmable register for initializing the part and setting the gain and power consumption. The four MSBs are address bits; the eight least significant bits (LSBs) are used for register data. Data is shifted MSB first.The serial interface should only be written to when TXEN = low, as is the case between transmit bursts in a DOCSIS environment. Once a new set of register data is clocked in, the corresponding power code and/or gain code does not take effect until the 12th rising edge of SCLK.Note: The registers must be written no earlier than 100μs after the device is powered up.MAX3523Low-Power DOCSIS 3.1 Programmable-Gain AmplifierSPI ReadFigure 1 shows a single-byte read transaction. In this example, a single byte is read from the slave by the master. The master first asserts CSB, begins driving SDA with the R/Wb bit having value of 1 indicating this a read transaction and starts toggling SCLK. The slave samples the bits on SDA on the rising edge of SCLK. After the R/Wb bit, the master outputs the 3-bit register addresses starting with the most significant bit following which the master releases the SDA line. The slave then starts driving SDA and outputs the single byte that was requested by the master. After the last bit has been output, the slave three-states SDA on the rising edge of CSB that ends the transaction.SPI WriteFigure 2 shows a single-byte write transaction. In this example, a single byte is written to the slave by the master. The master first asserts CSB, begins driving SDA with the R/Wb bit having value of 0 indicating this a write transaction and starts toggling SCLK. The slave samples the bits on SDA on the rising edge of SCLK. After the R/Wb bit, the master outputs the 3-bit register addresses starting with the most significant bit and then the 8-bit data starting with the most significant bit. The internal registers are updated on the 12th rising edge of SCLK.Figure 1. SPI Read TransactionFigure 2.

Using lower power codes (PC = 2, 1 or 0) allows for operation at reduced current levels. The full range of gain codes can be used in any power code. The gain difference between power codes is typically less than 0.1dB. Transmit Disable ModeBetween bursts in a DOCSIS system, the MAX3523 can be put in transmit-disable mode by setting TXEN low. The output transient on the cable is kept well below the DOCSIS 3.1 requirement during the TXEN transitions.If a gain code or power code change is required, the new values of PC and GC should be clocked in during transmit-disable mode (TXEN low). The new operating point of the MAX3523 is set on the 12th rising edge of SCLK. This should be done between transmission bursts.Output CircuitThe output circuit is an open-drain differential amplifier. The outputs should be resistively terminated, as shown in the Typical Application Circuit. A 50:75 impedance ratio transformer should be used as the interface between the differential output of the device and the unbalanced 75Ω load.Amplifier performance depends on the value of the termination resistors. Rated performance is obtained using the R7 termination resistor as shown in the Typical Application Circuit. Increasing the value of this resistor will increase gain and improve SNR at the expense of output return loss.Transformer core inductance may vary with temperature. Adequate primary inductance must be present to sustain broadband output capability as temperatures vary.Input CircuitThe differential input impedance of the MAX3523 is 200Ω. In a typical application, however, it is driven from a 100Ω differential source, requiring an external 200Ω matching resistor, as shown in the Typical Application Circuit.The device has sufficient gain and linearity to produce an output level of +68dBmV when driven with a +31dBmV input signal. If an input level greater than +31dBmV is used, the 3rd-order distortion performance yout IssuesA well-designed printed circuit board (PCB) is an essential part of an RF circuit. For best performance, pay attention to power-supply layout issues as well as the output circuit layout. The MAX3523 evaluation (EV) board layout can be utilized as a guide during PCB design. Its electrical performance has been thoroughly tested, making it an excellent reference. Refer to the MAX3523 EV kit for additional information.Output Circuit LayoutKeep the length of the output traces as short as possible. Series inductance between the part and the transformer will degrade the performance at the higher end of the operating frequency range. To maintain the balance of the output network, match the length of the differential traces as closely as possible.Power-Supply LayoutFor minimal coupling between different sections of the IC, the ideal power-supply layout is a star configuration. This configuration has a large-value decoupling capaci t or at the central power-supply node. The power-supply traces branch out from this node, each going to a sepa r ate power-supply node in the circuit. At the end of each of these traces is a decoupling capacitor that provides a very low impedance at the frequency of interest. This arrangement provides local power-supply decoupling at each power-supply pin. The power-supply traces must be capable of carrying the maximum current without signifi-cant voltage drop.Exposed Pad Thermal ConsiderationsThe exposed pad (EP) of the MAX3523's 20-pin TQFN package provides a low thermal resistance path to the die. It is important that the PCB on which the device is mounted be designed to conduct heat from this contact. In addition, the EP should be provided with a low-induc-tance path to electrical ground. The MAX3523 EV board is an example of a layout that provides optimal thermal and electrical performance.* EP = Exposed pad.+ Denotes a lead(Pb)-free/RoHS-compliant package.T Denotes tape-and-reel.PART NUMBER TEMP RANGE PIN-PACKAGE MAX3523ETP+0°C to +70°C20 TQFN-EP* MAX3523ETP+T0°C to +70°C20 TQFN-EP* Ordering InformationProgrammable-Gain AmplifierREVISION NUMBERREVISION DATE DESCRIPTIONPAGES CHANGED6/18Initial release—Revision HistoryMaxim Integrated cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim Integrated product.

For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,or visit Maxim's website at .General DescriptionThe MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E +3.0V-powered EIA/TIA-232 and V.28/V.24communications interface devices feature low power con-sumption, high data-rate capabilities, and enhanced electrostatic-discharge (ESD) protection. The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-G ap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge (±9kV for MAX3246E), and ±15kV using the Human Body Model. The logic and receiver I/O pins of the MAX3237E are protected to the above standards, while the transmit-ter output pins are protected to ±15kV using the Human Body Model.A proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply, using an internal dual charge pump. The charge pump requires only four small 0.1µF capacitors for opera-tion from a +3.3V supply. Each device guarantees opera-tion at data rates of 250kbps while maintaining RS-232output levels. The MAX3237E guarantees operation at 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232-compliant output levels.The MAX3222E/MAX3232E have two receivers and two transmitters. The MAX3222E features a 1µA shutdown mode that reduces power consumption in battery-pow-ered portable systems. The MAX3222E receivers remain active in shutdown mode, allowing monitoring of external devices while consuming only 1µA of supply current. The MAX3222E and MAX3232E are pin, package, and func-tionally compatible with the industry-standard MAX242and MAX232, respectively.The MAX3241E/MAX3246E are complete serial ports (three drivers/five receivers) designed for notebook and subnotebook computers. The MAX3237E (five drivers/three receivers) is ideal for peripheral applications that require fast data transfer. These devices feature a shut-down mode in which all receivers remain active, while consuming only 1µA (MAX3241E/MAX3246E) or 10nA (MAX3237E).The MAX3222E, MAX3232E, and MAX3241E are avail-able in space-saving SO, SSOP, TQFN and TSSOP pack-ages. The MAX3237E is offered in an SSOP package.The MAX3246E is offered in the ultra-small 6 x 6 UCSP™package.ApplicationsBattery-Powered Equipment PrintersCell PhonesSmart Phones Cell-Phone Data Cables xDSL ModemsNotebook, Subnotebook,and Palmtop ComputersNext-Generation Device Features♦For Space-Constrained ApplicationsMAX3228E/MAX3229E: ±15kV ESD-Protected, +2.5V to +5.5V, RS-232 Transceivers in UCSP ♦For Low-Voltage or Data Cable ApplicationsMAX3380E/MAX3381E: +2.35V to +5.5V, 1µA, 2Tx/2Rx, RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic PinsMAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246E±15kV ESD-Protected, Down to 10nA, 3.0V to 5.5V ,Up to 1Mbps, True RS-232 Transceivers________________________________________________________________Maxim Integrated Products 119-1298; Rev 11; 10/07Ordering Information continued at end of data sheet.*Dice are tested at T A = +25°C, DC parameters only.**EP = Exposed paddle.Pin Configurations, Selector Guide, and Typical Operating Circuits appear at end of data sheet.MegaBaud and UCSP are trademarks of Maxim Integrated Products, Inc.†Covered by U.S. Patent numbers 4,636,930; 4,679,134;4,777,577; 4,797,899; 4,809,152; 4,897,774; 4,999,761; and other patents pending.M A X 3222E /M A X 3232E /M A X 3237E /M A X 3241E †/M A X 3246EUp to 1Mbps, True RS-232 TransceiversABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V CC = +3V to +5.5V, C1–C4 = 0.1µF, T A = T MIN to T MAX , unless otherwise noted.

The charge pump operates in discontinuous mode; if the output voltages are less than 5.5V, the charge pump is enabled, and if the output voltages exceed 5.5V, the charge pump is disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies (Figure 1).RS-232 TransmittersThe transmitters are inverting level translators that con-vert TTL/CMOS-logic levels to ±5V EIA/TIA-232-compli-ant levels.The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF,providing compatibility with PC-to-PC communication software (such as LapLink™). Transmitters can be par-alleled to drive multiple receivers or mice.The MAX3222E/MAX3237E/MAX3241E/MAX3246E transmitters are disabled and the outputs are forcedinto a high-impedance state when the device is in shut-down mode (SHDN = G ND). The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E permit the outputs to be driven up to ±12V in shutdown.The MAX3222E/MAX3232E/MAX3241E/MAX3246E transmitter inputs do not have pullup resistors. Connect unused inputs to GND or V CC . The MAX3237E’s trans-mitter inputs have a 400k Ωactive positive-feedback resistor, allowing unused inputs to be left unconnected.MAX3237E MegaBaud OperationFor higher-speed serial communications, the MAX3237E features MegaBaud operation. In MegaBaud operating mode (MBAUD = V CC ), the MAX3237E transmitters guarantee a 1Mbps data rate with worst-case loads of 3k Ωin parallel with 250pF for +3.0V < V CC < +4.5V. For +5V ±10% operation, the MAX3237E transmitters guarantee a 1Mbps data rate into worst-case loads of 3k Ωin parallel with 1000pF.RS-232 ReceiversThe receivers convert RS-232 signals to CMOS-logic output levels. The MAX3222E/MAX3237E/MAX3241E/MAX3246E receivers have inverting three-state outputs.Drive EN high to place the receiver(s) into a high-impedance state. Receivers can be either active or inactive in shutdown (Table 1).Figure 1. Slew-Rate Test CircuitsLapLink is a trademark of Traveling Software.M A X 3222E /M A X 3232E /M A X 3237E /M A X 3241E †/M A X 3246EUp to 1Mbps, True RS-232 Transceivers10______________________________________________________________________________________The complementary outputs on the MAX3237E/MAX3241E (R_OUTB) are always active, regardless of the state of EN or SHDN . This allows the device to be used for ring indicator applications without forward biasing other devices connected to the receiver outputs. This is ideal for systems where V CC drops to zero in shutdown to accommodate peripherals such as UARTs (Figure 2).MAX3222E/MAX3237E/MAX3241E/MAX3246E Shutdown ModeSupply current falls to less than 1µA in shutdown mode (SHDN = low). The MAX3237E’s supply current falls to10nA (typ) when all receiver inputs are in the invalid range (-0.3V < R_IN < +0.3). When shut down, the device’s charge pumps are shut off, V+ is pulled down to V CC , V- is pulled to ground, and the transmitter out-puts are disabled (high impedance). The time required to recover from shutdown is typically 100µs, as shown in Figure 3. Connect SHDN to V CC if shutdown mode is not used. SHDN has no effect on R_OUT or R_OUTB (MAX3237E/MAX3241E).±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated to protect against electrostatic dis-charges encountered during handling and assembly.The driver outputs and receiver inputs of the MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage.The ESD structures withstand high ESD in all states:normal operation, shutdown, and powered down. After an ESD event, Maxim’s E versions keep working without latchup, whereas competing RS-232 products can latch and must be powered down to remove latchup.Furthermore, the MAX3237E logic I/O pins also have ±15kV ESD protection. Protecting the logic I/O pins to ±15kV makes the MAX3237E ideal for data cable applications.SHDN T2OUTT1OUT5V/div2V/divV CC = 3.3V C1–C4 = 0.1μFFigure 3. Transmitter Outputs Recovering from Shutdown or Powering UpMAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversESD protection can be tested in various ways; the transmitter outputs and receiver inputs for the MAX3222E/MAX3232E/MAX3241E/MAX3246E are characterized for protection to the following limits:•±15kV using the Human Body Model•±8kV using the Contact Discharge method specified in IEC 1000-4-2•±9kV (MAX3246E only) using the Contact Discharge method specified in IEC 1000-4-2•±15kV using the Air-G ap Discharge method speci-fied in IEC 1000-4-2Figure 4a.

This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E help you design equipment that meets level 4 (the highest level)of IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model. Figure 5a shows the IEC 1000-4-2 model, and Figure 5b shows the current waveform for the ±8kV IEC 1000-4-2 level 4 ESD Contact Discharge test. The Air-G ap Discharge test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. All pins require this protection during manufacturing, not just RS-232 inputs and outputs.Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Table 2. Required Minimum Capacitor ValuesFigure 6a. MAX3241E Transmitter Output Voltage vs. Load Current Per TransmitterTable 3. Logic-Family Compatibility with Various Supply VoltagesMAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversApplications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; polarized or nonpolarized capacitors can be used. The charge pump requires 0.1µF capaci-tors for 3.3V operation. For other supply voltages, see Table 2 for required capacitor values. Do not use val-ues smaller than those listed in Table 2. Increasing the capacitor values (e.g., by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1without also increasing the values of C2, C3, C4,and C BYPASS to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degradeexcessively with temperature. If in doubt, use capaci-tors with a larger nominal value. The capacitor’s equiv-alent series resistance (ESR), which usually rises at low temperatures, influences the amount of ripple on V+and V-.Power-Supply DecouplingIn most circumstances, a 0.1µF V CC bypass capacitor is adequate. In applications sensitive to power-supply noise, use a capacitor of the same value as charge-pump capacitor C1. Connect bypass capacitors as close to the IC as possible.Operation Down to 2.7VTransmitter outputs meet EIA/TIA-562 levels of ±3.7V with supply voltages as low as 2.7V.Figure 6b.

As they become active, the two trans-mitter outputs are shown going to opposite RS-232 levels (one transmitter input is high; the other is low). Each transmitter is loaded with 3k Ωin parallel with 2500pF.The transmitter outputs display no ringing or undesir-able transients as they come out of shutdown. Note thatthe transmitters are enabled only when the magnitude of V- exceeds approximately -3.0V.Mouse DrivabilityThe MAX3241E is designed to power serial mice while operating from low-voltage power supplies. It has been tested with leading mouse brands from manu-facturers such as Microsoft and Logitech. The MAX3241E successfully drove all serial mice tested and met their current and voltage requirements.MAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversFigure 6a shows the transmitter output voltages under increasing load current at +3.0V. Figure 6b shows a typical mouse connection using the MAX3241E.High Data RatesThe MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E maintain the RS-232 ±5V minimum transmit-ter output voltage even at high data rates. Figure 7shows a transmitter loopback test circuit. Figure 8shows a loopback test result at 120kbps, and Figure 9shows the same test at 250kbps. For Figure 8, all trans-mitters were driven simultaneously at 120kbps into RS-232 loads in parallel with 1000pF. For Figure 9, a single transmitter was driven at 250kbps, and all transmitters were loaded with an RS-232 receiver in parallel with 1000pF.The MAX3237E maintains the RS-232 ±5.0V minimum transmitter output voltage at data rates up to 1Mbps.Figure 10 shows a loopback test result at 1Mbps with MBAUD = V CC . For Figure 10, all transmitters were loaded with an RS-232 receiver in parallel with 250pF.Interconnection with 3V and 5V LogicThe MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E can directly interface with various 5V logic families, including ACT and HCT CMOS. See Table 3for more information on possible combinations of inter-connections.UCSP ReliabilityThe UCSP represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environ-ment. The user should closely review these areas when considering use of a UCSP package. Performance through Operating Life Test and Moisture Resistance remains uncompromised as the wafer-fabrication process primarily determines it.Mechanical stress performance is a greater considera-tion for a UCSP package. UCSPs are attached through direct solder contact to the user’s PC board, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be consid-ered. Table 4 shows the testing done to characterize the UCSP reliability performance. In conclusion, the UCSP is capable of performing reliably through envi-ronmental stresses as indicated by the results in the table. Additional usage data and recommendations are detailed in the UCSP application note, which can be found on Maxim’s website at .Table 4.

+60V Simple Swapper Hot-Swap Switch
General Description
The MAX5923 is a fully integrated Simple Swapper™ hot-swap switch for positive supply rails. The device allows the safe insertion and removal of circuit cards into live backplanes or ports without causing glitches on the power-supply rail. The device also monitors various circuit parameters and disconnects the load if a fault condition occurs, alerting the host with a logiclevel FAULT output. The MAX5923 operates over the +16V to +60V input voltage range. During startup, an integrated 0.45Ω power MOSFET regulates the current and voltage between the backplane power source and the load. After startup, the MOSFET is fully enhanced to reduce its on-resistance. To ensure robust operation, the MAX5923 contains built-in safety features that monitor fault conditions and prevent damage to the internal MOSFET. The MAX5923 monitors three parameters for fault conditions: zero current, overcurrent, and thermal overload. The output overcurrent limit counts the time the MAX5923 spends in an overcurrent condition and shuts down the pass transistor if the current limit is exceeded for the overcurrent time limit. The zero-current detection counts the time the output current is below the zero-current threshold and shuts down the pass transistor if the counter reaches the zero-current time limit. The thermal monitoring feature shuts down the pass transistor if the die temperature reaches the overtemperature limit. A fault logic output indicates when an overtemperature or an overcurrent condition has occurred and a zero-current logic output indicates if there is a zero-current condition. An undervoltage detection circuitry keeps the pass transistor off until the input voltage is above the undervoltage lockout (UVLO) threshold, which is internally set or can be set externally with a resistive divider. A power-OK (POK) output is provided to signal when the output voltage has reached to within 0.75V of the input voltage. An Enable input allows the host system to disconnect the system from the load and/or reset a fault condition by toggling Enable. The MAX5923 is available in a 20-pin TSSOP package and operates in the extended -40°C to +85°C temperature range. o 0.45Ω Integrated Power Switch o Programmable Output Current Up to 800mA o Over/Undercurrent-Limit Detection o Input Logic Signals Compatible with 1.8V to 5V CMOS Logic o Separate Analog and Digital Grounds with Up to ±4V Offset o Power-OK Status Output o Overcurrent Protection with Status Outputs o Built-In Thermal Shutdown o Internal Switch Protection Circuitry o Current-Limit Foldback with Timeout and DutyCycle Control o Latch or Autorestart Fault Management
