MAX3230E_08资料

General DescriptionThe MAX3230E/AE and MAX3231E/AE are +2.5V to +5.5V powered EIA/TIA-232 and V.28/V.24 communica-tions interfaces with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection, in a chip-scale package (UCSP™)and WLP package. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using I EC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model.The MAX3230E/AE and MAX3231E/AE achieve a 1µA supply current with Maxim’s AutoShutdown™ feature.They save power without changing the existing BIOS or operating systems by entering low-power shutdown mode when the RS-232 cable is disconnected, or when the transmitters of the connected peripherals are off.The transceivers have a proprietary low-dropout trans-mitter output stage, delivering RS-232-compliant perfor-mance from a +3.1V to +5.5V supply, and RS-232-compatible performance with a supply voltage as low as +2.5V. The dual charge pump requires only four,small 0.1µF capacitors for operation from a +3.0V sup-ply. Each device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels.The MAX3230E/AE and MAX3231E/AE offer a separate power-supply input for the logic interface, allowing con-figurable logic levels on the receiver outputs and trans-mitter inputs. Operating over a +1.65V to V CC range, V L provides the MAX3230E/AE and MAX3231E/AE com-patibility with multiple logic families.The MAX3231E/AE contains one receiver and one trans-mitter. The MAX3230E/AE contains two receivers and two transmitters. The MAX3230E/AE and MAX3231E/AE are available in tiny chip-scale and WLP packaging and are specified across the extended industrial (-40°C to +85°C)temperature range.ApplicationsPersonal Digital Assistants Cell-Phone Data Lump Cables Set-Top Boxes Handheld Devices Cell PhonesFeatures♦6 x 5 Chip-Scale Package (UCSP) and WLP Package♦ESD Protection for RS-232 I/O Pins±15kV—IEC 1000-4-2 Air-Gap Discharge ±8kV—IEC 1000-4-2 Contact Discharge ±15kV—Human Body Model ♦1µA Low-Power AutoShutdown ♦250kbps Guaranteed Data Rate♦Meet EIA/TIA-232 Specifications Down to +3.1V ♦RS-232 Compatible to +2.5V Allows Operation from Single Li+ Cell ♦Small 0.1µF Capacitors ♦Configurable Logic LevelsMAX3230E/MAX3230AE/MAX3231E/MAX3231AE±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP________________________________________________________________Maxim Integrated Products 1Typical Operating Circuits19-3250; Rev 1; 10/08For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .Ordering InformationUCSP is a trademark of Maxim Integrated Products, Inc.AutoShutdown is a trademark of Maxim Integrated Products, Inc.Typical Operating Circuits continued at end of data sheet.Pin Configurations appear at end of data sheet.+Denotes a lead-free/RoHS-compliant package.T = Tape-and-reel.M A X 3230E /M A X 3230A E /M A X 3231E /M A X 3231A E±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

For supply voltages above +3.7V, the charge pump generates +5.5V at V+ and -5.5V at V-. The charge pumps operate in a discontinuous mode. If the output voltages are less than ±5.5V, the charge pumps are enabled. I f the output voltages exceed ±5.5V, the charge pumps are disabled.For supply voltages below +2.85V, the charge pump generates +4.0V at V+ and -4.0V at V-. The charge pumps operate in a discontinuous mode. I f the output voltages are less than ±4.0V, the charge pumps are enabled. I f the output voltages exceed ±4.0V, the charge pumps are disabled.Each charge pump requires a flying capacitor (C1, C2)and a reservoir capacitor (C3, C4) to generate the V+and V- supply voltages.Voltage Generation in theSwitchover RegionThe MAX3230E/AE and MAX3231E/AE include a switchover circuit between these two modes that have approximately 400mV of hysteresis around the switchover point. The hysteresis is shown in Figure 1.This large hysteresis eliminates mode changes due to power-supply bounce.For example, a three-cell NiMh battery system starts at V CC = +3.6V, and the charge pump generates an out-put voltage of ±5.5V. As the battery discharges, the MAX3230E/AE and MAX3231E/AE maintain the outputsThe output regulation points then change to ±4.0V.When V CC is rising, the charge pump generates an out-put voltage of ±4.0V, while V CC is between +2.5V and +3.5V. When V CC rises above the switchover voltage of +3.5V, the charge pump switches modes to generate an output of ±5.5V.Table 1 shows different supply schemes and their oper-ating voltage ranges.RS-232 TransmittersThe transmitters are inverting level translators that convert CMOS logic levels to RS-232 levels. The MAX3230E/AE and MAX3231E/AE automatically reduce the RS-232-compliant levels (±5.5V) to RS-232-compat-ible levels (±4.0V) when V CC falls below approximately +3.1V. The reduced levels also reduce supply-current requirements, extending battery life. Built-in hysteresis of approximately 400mV for V CC ensures that the RS-Figure 1. V+ Switchover for Changing V CC6V4V20ms/divV CCV+Dual Mode is a trademark of Maxim Integrated Products, Inc.MAX3230E/MAX3230AE/MAX3231E/MAX3231AE232 output levels do not change if V CC is noisy or has a sudden current draw causing the supply voltage to drop slightly. The outputs return to RS-232-compliant levels (±5.5V) when V CC rises above approximately +3.5V.The MAX3230E/AE and MAX3231E/AE transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF.When FORCEOFF is driven to ground, the transmitters and receivers are disabled and the outputs become high impedance. When the AutoShutdown circuitry senses that all receiver and transmitter inputs are inac-tive for more than 30µs, the transmitters are disabled and the outputs go to a high-impedance state. When the power is off, the MAX3230E/AE and MAX3231E/AE permit the transmitter outputs to be driven up to ±12V.The transmitter inputs do not have pullup resistors.Connect unused inputs to GND or V L .RS-232 ReceiversThe MAX3230E/AE and MAX3231E/AE receivers con-vert RS-232 signals to logic-output levels. All receivers have inverting tri-state outputs and can be active or inactive. I n shutdown (FORCEOFF = low) or in AutoShutdown, the MAX3230E/AE and MAX3231E/AE receivers are in a high-impedance state (Table 2).The MAX3230E/AE and MAX3231E/AE feature an INVALID output that is enabled low when no valid RS-232signal levels have been detected on any receiver inputs.INVALID is functional in any mode (Figures 2 and 3).AutoShutdownThe MAX3230E/AE and MAX3231E/AE achieve a 1µA supply current with Maxim’s AutoShutdown feature,which operates when FORCEON is low and FORCEOFF is high. When these devices sense no valid signal lev-els on all receiver inputs for 30µs, the on-board charge pump and drivers are shut off, reducing V CC supply current to 1µA. This occurs if the RS-232 cable is dis-connected or the connected peripheral transmitters are turned off. The device turns on again when a valid level is applied to any RS-232 receiver input. As a result, the system saves power without changes to the existing BIOS or operating system.Table 2 and Figure 2c summarize the MAX3230E/AE and MAX3231E/AE operating modes. FORCEON and FORCEOFF override AutoShutdown. When neither con-trol is asserted, the I C selects between these states automatically, based on receiver input levels. Figures 2a, 2b, and 3a depict valid and invalid RS-232-receiver levels. Figures 3a and 3b show the input levels and tim-ing diagram for AutoShutdown operation.A system with AutoShutdown can require time to wake up. Figure 4 shows a circuit that forces the transmitters on for 100ms, allowing enough time for the other system to realize that the MAX3230E/AE and±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP_______________________________________________________________________________________7MAX3231E/AE are active. If the other system transmits valid RS-232 signals within that time, the RS-232 ports on both systems remain enabled.When shut down, the device’s charge pumps are off,V+ is pulled to V CC , V- is pulled to ground, and the transmitter outputs are high impedance. The time required to exit shutdown is typically 100µs (Figure 3b).V L Logic Supply InputUnlike other RS-232 interface devices, where the receiv-er outputs swing between 0 and V CC , the MAX3230E/AE and MAX3231E/AE feature a separate logic supply input (V L ) that sets V OH for the receiver outputs. The transmit-ter inputs (T_IN), FORCEON, and FORCEOFF , are also referred to V L . This feature allows maximum flexibility in interfacing to different systems and logic levels.Connect V L to the system’s logic supply voltage (+1.65V to +5.5V), and bypass it with a 0.1µF capacitor to GND.I f the logic supply is the same as V CC , connect V L to V CC . Always enable V CC before enabling the V L supply.V CC must be greater than or equal to the V L supply.Software-Controlled ShutdownIf direct software control is desired, connect FORCEOFF and FORCEON together to disable AutoShutdown. Themicrocontroller (µC) then drives FORCEOFF and FORCEON like a SHDN input. INVALID can be used to alert the µC to indicate serial data activity.±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 MAX3230E/AE and MAX3231E/AE have extra protec-tion 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 power-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.ESD protection can be tested in various ways; the trans-mitter outputs and receiver inputs of this product family are characterized for protection to the following limits:1) ±15kV using the Human Body Model2) ±8kV using the Contact Discharge method specified in IEC 1000-4-23) ±15kV using the IEC 1000-4-2 Air-Gap methodESD 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 5a shows the Human Body Model.

MAX323_E AutoShutdown LogicMAX3230E/MAX3230AE/MAX3231E/MAX3231AEwhich 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 per-formance of finished equipment. It does not specifically refer to ICs. The MAX3230E/AE and MAX3231E/AE aid in designing equipment that meets Level 4 (the highest level) of I EC 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 a higher peak current in I EC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stands voltage measured to IEC 1000-4-2 and is gener-ally lower than that measured using the Human Body Model. Figure 6a shows the I EC 1000-4-2 model, and Figure 6b shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap 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 resistance. I ts objective is to emulate the stress caused by contact that occurs with handling and assembly during manufactur-ing. Of course, 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.Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; either polarized or nonpolarized capacitors can be used. However, ceramic chip capaci-tors with an X7R or X5R dielectric work best. The charge pump requires 0.1µF capacitors for 3.3V operation. For other supply voltages, see Table 3 for required capaci-tor values. Do not use values smaller than those listed in Table 3. Increasing the capacitor values (e.g., by a fac-tor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4can be increased without changing the vaue of C1.Caution: Do not increase C1 without also increasing the values of C2, C3, and C4 to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degrade exces-sively with temperature. If in doubt, use capacitors with±15kV ESD-Protected +2.5V to +5.5V RS-232 Transceivers in UCSP and WLP_______________________________________________________________________________________9Figure 3.

The capacitor’s equivalent series resistance (ESR) usually rises at low temperatures and 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 that are sensitive to power-supply noise, use a capacitor of the same value as the charge-pump capacitor C1. Connect bypass capaci-tors as close to the IC as possible.Transmitter Outputs whenExiting ShutdownFigure 7 shows a transmitter output when exiting shut-down mode. The transmitter is loaded with 3k Ωin par-allel with 1000pF. The transmitter output displays no ringing or undesirable transients as it comes out of shutdown, and is enabled only when the magnitude of V- exceeds approximately -3V.High Data RatesThe MAX3230E/AE and MAX3231E/AE maintain the RS-232 ±5.0V minimum transmitter output voltage even at high data rates. Figure 8 shows a transmitter loop-back test circuit. Figure 9 shows a loopback test result at 120kbps, and Figure 10 shows the same test at 250kbps. For Figure 9, the transmitter was driven at 120kbps into an RS-232 load in parallel with 1000pF.For Figure 10, a single transmitter was driven at 250kbps and loaded with an RS-232 receiver in paral-lel with 1000pF.Figure 6a.

MAX483EESA+T中文资料

General DescriptionThe MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environ-ments. Each driver output and receiver input is protected against ±15kV electro-static discharge (ESD) shocks,without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly termi-nated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E,MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw as little as 120µA supply cur-rent when unloaded or when fully loaded with disabled drivers (see Selector Guide ). Additionally, the MAX481E,MAX483E, and MAX487E have a low-current shutdown mode in which they consume only 0.5µA. All parts oper-ate from a single +5V supply.Drivers are short-circuit current limited, and are protected against excessive power dissipation by thermal shutdown circuitry that places their outputs into a high-impedance state. The receiver input has a fail-safe feature that guar-antees a logic-high output if the input is open circuit.The MAX487E and MAX1487E feature quarter-unit-load receiver input impedance, allowing up to 128 trans-ceivers on the bus. The MAX488E–MAX491E are designed for full-duplex communications, while the MAX481E, MAX483E, MAX485E, MAX487E, and MAX1487E are designed for half-duplex applications.For applications that are not ESD sensitive see the pin-and function-compatible MAX481, MAX483, MAX485,MAX487–MAX491, and MAX1487.ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area NetworksNext-Generation Device Features♦For Fault-Tolerant Applications:MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4-Unit Load, +3.3V, RS-485 TransceiverMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited, RS-485/RS-422Transceivers ♦For Space-Constrained Applications:MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus, RS-485/RS-422 TransceiversMAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 PackageMAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422True Fail-Safe ReceiversMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Multiple Transceiver Applications:MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters ♦For Fail-Safe Applications:MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe RS-485/J1708 Transceivers ♦For Low-Voltage Applications:MAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited, True RS-485/RS-422 TransceiversMAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers________________________________________________________________Maxim Integrated Products 1Ordering Information19-0410; Rev 4; 10/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering Information continued at end of data sheet.Selector Guide appears at end of data sheet .M A X 481E /M A X 483E /M A X 485E /M A X 487E –M A X 491E /M A X 1487E±15kV ESD-Protected, Slew-Rate-Limited,Low-Power, RS-485/RS-422 Transceivers2_______________________________________________________________________________________Supply Voltage (V CC ) (12V)Control Input Voltage (–R —E –, DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (Y, Z; A, B)..........................-8V to +12.5V Receiver Input Voltage (A, B).................................-8V to +12.5V Receiver Output Voltage (RO)....................-0.5V to (V CC + 0.5V)Continuous Power Dissipation (T A = +70°C)8-Pin Plastic DIP (derate 9.09mW/°C above +70°C)....727mW14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW 14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW Operating Temperature RangesMAX4_ _C_ _/MAX1487EC_ A.............................0°C to +70°C MAX4__E_ _/MAX1487EE_ A...........................-40°C to +85°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10sec).............................+300°CDC ELECTRICAL CHARACTERISTICS(V CC = 5V ±5%, T A = T MIN to T MAX , unless otherwise noted.)

Transmitting__________Applications Information The MAX481E/MAX483E/MAX485E/MAX487E–MAX491E and MAX1487E are low-power transceivers for RS-485 and RS-422 communications. These “E” versions of the MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 provide extra protection against ESD. The rugged MAX481E, MAX483E, MAX485E, MAX497E–MAX491E, and MAX1487E are intended for harsh envi-ronments where high-speed communication is important. These devices eliminate the need for transient suppres-sor diodes and the associated high capacitance loading. The standard (non-“E”) MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are recommended for applications where cost is critical.The MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E can transmit and receive at data rates up to 2.5Mbps, while the MAX483E, MAX487E, MAX488E, and MAX489E are specified for data rates up to 250kbps. The MAX488E–MAX491E are full-duplex transceivers, while the MAX481E, MAX483E, MAX487E, and MAX1487E are half-duplex. In addition, driver-enable (DE) and receiver-enable (RE) pins are included on the MAX481E, MAX483E, MAX485E, MAX487E, MAX489E, MAX491E, and MAX1487E. When disabled, the driver and receiver outputs are high impedance.±15kV ESD Protection As 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 have extra protection against static electricity. Maxim’s engi-neers 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 MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E keep working without latchup.ESD protection can be tested in various ways; the transmitter outputs and receiver inputs of this product family are characterized for protection to ±15kV using the Human Body Model.Other ESD test methodologies include IEC10004-2 con-tact discharge and IEC1000-4-2 air-gap discharge (for-merly IEC801-2).ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test set-up, test methodology, and test results.Human Body Model Figure 4 shows the Human Body Model, and Figure 5 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 inter-est, which is then discharged into the test device through a 1.5kΩresistor.IEC1000-4-2 The IEC1000-4-2 standard covers ESD testing and per-formance of finished equipment; it does not specifically refer to integrated circuits (Figure 6).MAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E±15kV ESD-Protected, Slew-Rate-Limited,Low-Power, RS-485/RS-422 Transceivers_______________________________________________________________________________________9M A X 481E /M A X 483E /M A X 485E /M A X 487E –M A X 491E /M A X 1487E±15kV ESD-Protected, Slew-Rate-Limited,Low-Power, RS-485/RS-422 Transceivers10______________________________________________________________________________________Figure 8.

Hence, the ESD with-stand voltage measured to IEC1000-4-2 is generally lower than that measured using the Human Body Model. Figure 7 shows the current waveform for the 8kV IEC1000-4-2 ESD contact-discharge test.The air-gap 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. Of course, all pins require this protec-tion during manufacturing—not just inputs and outputs.Therefore,after PC board assembly,the Machine Model is less relevant to I/O ports.MAX487E/MAX1487E:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487E and MAX1487E allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 transceivers maximum). Any combination of MAX487E/MAX1487E and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481E,MAX483E, MAX485E, and MAX488E–MAX491E have standard 12k Ωreceiver input impedance.MAX483E/MAX487E/MAX488E/MAX489E:Reduced EMI and Reflections The MAX483E and MAX487E–MAX489E are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. Figure 16shows the driver output waveform and its Fourier analy-sis of a 150kHz signal transmitted by a MAX481E,MAX485E, MAX490E, MAX491E, or MAX1487E. High-frequency harmonics with large amplitudes are evident.Figure 17 shows the same information displayed for a MAX483E, MAX487E, MAX488E, or MAX489E transmit-ting under the same conditions. Figure 17’s high-fre-quency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.Low-Power Shutdown Mode (MAX481E/MAX483E/MAX487E)A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled.In shutdown, the devices typically draw only 0.5µA of supply current.RE and DE may be driven simultaneously; the parts 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 600ns, the parts are guaranteed to enter shutdown.For the MAX481E, MAX483E, and MAX487E, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485E, MAX488E–MAX491E, and MAX1487E can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).500kHz/div0Hz5MHz 10dB/div Figure 16.

Driver Output Waveform and FFT Plot ofMAX483E/MAX487E–MAX489E Transmitting a 150kHz SignalIt takes the drivers and receivers longer to become enabled from the low-power shutdown state (t ZH(SHDN), t ZL(SHDN)) than from the operating mode (t ZH, t ZL). (The parts are in operating mode if the RE, DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output Protection Excessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short circuits over the whole common-mode voltage range (see Typical Operating Characteristics). In addition, a thermal shut-down circuit forces the driver outputs into a high-imped-ance state if the die temperature rises excessively.Propagation Delay Many digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 19–22 using Figure 18’s test circuit.The difference in receiver delay times, t PLH- t PHL, is typically under 13ns for the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E, and is typically less than 100ns for the MAX483E and MAX487E–MAX489E.The driver skew times are typically 5ns (10ns max) for the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E, and are typically 100ns (800ns max) for the MAX483E and MAX487E–MAX489E.Typical Applications The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E transceivers are designed for bidirectional data communications on multipoint bus transmission lines. Figures 25 and 26 show typical net-work application circuits. These parts can also be used as line repeaters, with cable lengths longer than 4000 feet. To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possi-ble. The slew-rate-limited MAX483E and MAX487E–MAX489E are more tolerant of imperfect termination. Bypass the V CC pin with 0.1µF.Isolated RS-485 For isolated RS-485 applications, see the MAX253 and MAX1480 data sheets.Line Length vs. Data Rate The RS-485/RS-422 standard covers line lengths up to 4000 feet.

Unlike conventional shunt-mode (two-terminal) references that must be biased at the load current and require an exter-nal resistor, these devices eliminate the need for an external resistor and offer a supply current that is virtually independent of the supply voltage.These micropower, low-dropout, low-cost devices are ideal for high-volume, cost-sensitive 3V and 5V battery-operated systems with wide variations in supply voltage that require very low power dissipation. Additionally,these devices are internally compensated and do not require an external compensation capacitor, saving valuable board area in space-critical applications.ApplicationsPortable/Battery-Powered Equipment Notebook Computers PDAs, GPSs, and DMMs Cellular Phones PagersHard-Disk DrivesFeatureso 1% max Initial Accuracyo 100ppm/°C max Temperature Coefficient o 45µA max Quiescent Supply Current o 0.8µA/V Supply Current Variation with V IN o ±400µA Output Source and Sink Current o 100mV Dropout at 400µA Load Current o 0.12µV/µA Load Regulation o 8µV/V Line Regulationo Stable with C LOAD = 0 to 2.2nFMAX6001–MAX6005Low-Cost, Low-Power, Low-Dropout,SOT23-3 Voltage References________________________________________________________________Maxim Integrated Products 1Typical Operating Circuit13-1395; Rev 1; 4/99Ordering InformationSelector GuidePin ConfigurationM A X 6001–M A X 6005Low-Cost, Low-Power, Low-Dropout, SOT23-3 Voltage References 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS—MAX6001(V IN = +5V, I OUT = 0, T A = T MIN to T MAX , unless otherwise noted.

The Typical Operating Characteristics of the remainder of the MAX6001 family typically lie between these two extremes and can be estimated based on their output voltage.M A X 6001–M A X 6005Low-Cost, Low-Power, Low-Dropout, SOT23-3 Voltage References 10______________________________________________________________________________________Detailed DescriptionThe MAX6001–MAX6005 bandgap references offer a temperature coefficient of <100ppm/°C and initial accura-cy of better than 1%. These devices can sink and source up to 400µA with <200mV of dropout voltage, making them attractive for use in low-voltage applications.Applications InformationOutput/Load CapacitanceDevices in this family do not require an output capaci-tance for frequency stability. They are stable for capac-itive loads from 0 to 2.2nF. However, in applications where the load or the supply can experience step changes, an output capacitor will reduce the amount of overshoot (or undershoot) and assist the circuit’s tran-sient response. Many applications do not need an external capacitor, and this family can offer a signifi-cant advantage in these applications when board space is critical.Supply CurrentThe quiescent supply current of these series-mode ref-erences is a maximum of 45µA and is virtually indepen-dent of the supply voltage, with only a 0.8µA/V variation with supply voltage. Unlike shunt-mode references, the load current of these series-mode references is drawn from the supply voltage only when required, so supply current is not wasted and efficiency is maximized over the entire supply voltage range. This improved efficien-cy can help reduce power dissipation and extend bat-tery life.When the supply voltage is below the minimum speci-fied input voltage (as during turn-on), the devices can draw up to 200µA beyond the nominal supply current.The input voltage source must be capable of providing this current to ensure reliable turn-on.Output Voltage HysteresisOutput voltage hysteresis is the change in the output voltage at T A = +25°C before and after the device is cycled over its entire operating temperature range.Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 130ppm.Figure 1.

The turn-on time can increase up to 1.5mswith the device operating at the minimum dropout volt-age and the maximum load.Positive and NegativeLow-Power Voltage ReferenceFigure 1 shows a typical method for developing a bipo-lar reference.

General DescriptionThe MAX4822–MAX4825 8-channel relay drivers offer built-in kickback protection and drive +3V/+5V non-latching or dual-coil-latching relays. Each independent open-drain output features a 2.7Ω(typ) on-resistance and is guaranteed to sink 70mA (min) of load current.These devices consume less than 300µA (max) quies-cent current and have 1µA output off-leakage current.A Zener-kickback-protection circuit significantly reduces recovery time in applications where switching speed is critical.The MAX4822/MAX4824 feature a unique power-save mode where the relay current, after activation, can be reduced to a level just above the relay hold-current threshold. This mode keeps the relay activated while significantly reducing the power consumption.The MAX4822/MAX4823 feature a 10MH z SPI™-/QSPI™-/MICROWIRE™-compatible serial interface.Input data is shifted into a shift register and latched to the outputs when CS transitions from low to high. Each data bit in the shift register corresponds to a specific output, allowing independent control of all outputs. The MAX4824/MAX4825 feature a 4-bit parallel-input interface. The first 3 bits (A0, A1, A2) determine the out-put address, and the fourth bit (LVL) determines whether the selected output is switched on or off. Data is latched to the outputs when CS transitions from low to high.The MAX4822–MAX4825 feature separate set and reset functions, allowing turn-on or turn-off of all outputs simultaneously with a single control line. Built-in hys-teresis (Schmidt trigger) on all digital inputs allows these devices to be used with slow-rising and falling signals, such as those from optocouplers or RC power-up initialization circuits. The MAX4822–MAX4825 are available in space-saving 4mm x 4mm, 20-pin thin QFN packages. They are specified over the -40°C to +85°C extended temperature range.ApplicationsATE EquipmentDSL Redundancy Protection (ADSL/VDSL/HDSL)T1/E1 Redundancy Protection T3/E3 Redundancy Protection Industrial EquipmentTest Equipment (Oscilloscopes, Spectrum Analyzers)Features♦Built-In Zener Kickback Protection for Fast Recovery ♦Programmable Power-Save Mode Reduces Relay Power Consumption (MAX4822/MAX4824)♦10MHz SPI-/QSPI-/MICROWIRE-Compatible Serial Interface ♦Eight Independent Output Channels ♦Drive +3V and +5V Relays♦Guaranteed 70mA (min) Coil Drive Current ♦Guaranteed 5Ω(max) R ON♦SET / RESET Functions to Turn On/Off All Outputs Simultaneously ♦Serial Digital Output for Daisy Chaining ♦Optional Parallel Interface (MAX4824/MAX4825)♦Low 300µA (max) Quiescent Supply Current ♦Space-Saving, 4mm x 4mm, 20-Pin TQFN PackageMAX4822–MAX4825+3.3V/+5V , 8-Channel Relay Drivers with FastRecovery Time and Power-Save Mode________________________________________________________________Maxim Integrated Products1Ordering Information19-3789; Rev 0; 8/05For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .*For maximum heat dissipation, packages have an exposed pad (EP) on the bottom.

The MAX4823 does not support power-save mode, so the serial interface con-sists of an 8-bit-only shift register for faster control.The MAX4822 consists of a 16-bit shift register and par-allel latch controlled by SCLK and CS . The input to the shift register is a 16-bit word. In the MAX4822, the first 8 bits determine the register address and are followedsponds to the MSB of the 8-bit register address in Figure 1, while bit D7 corresponds to the MSB of the 8bits of data in the same Figure 1.The MAX4823 consists of an 8-bit shift register and par-allel latch controlled by SCLK and CS . The input to the shift register is an 8-bit word. Each data bit controls one of the eight outputs, with the most significant bit (D7) corresponding to OUT8, and the least significant bit (D0) corresponding to OUT1 (see Figure 2).MAX4822–MAX4825+3.3V/+5V , 8-Channel Relay Drivers with FastRecovery Time and Power-Save Mode_______________________________________________________________________________________9M A X 4822–M A X 4825When CS is low (MAX4822/MAX4823 device is select-ed), data at DIN is clocked into the shift register syn-chronously with SCLK’s rising edge. Driving CS from low to high latches the data in the shift register (Figures 5 and 6).DOUT is the output of the shift register. Data appears on DOUT synchronously with SCLK’s falling edge and is identical to the data at DIN delayed by eight clock cycles for the MAX4823, or 16 clock cycles for the MAX4822. When shifting the input data, A7 is the first input bit in and out of the shift register for the MAX4822device. D7 is the first bit in or out of the shift register for+3.3V/+5V , 8-Channel Relay Drivers with Fast Recovery Time and Power-Save Mode 10______________________________________________________________________________________Figure 1. 16-Bit Register Map for MAX4822the MAX4823 device. If the address A0…….A7 is not 00h or 01h, then the outputs and the PSAVE configura-tion register are not updated. The address is stored in the shift register only.While CS is low, the OUT_ outputs always remain in their previous state. For the MAX4823, drive CS high after 8bits of data have been shifted in to update the output state of the MAX4823, and to further inhibit data from entering the shift register. For the MAX4822, drive CS high after 16 bits of data have been shifted in to update the output state of the MAX4822, and to further inhibit data from entering the shift register. When CS is high, transi-tions at DIN and SCLK have no effect on the output, and the first input bit A7 (or D7) is present at DOUT.For the MAX4822, if the number of data bits entered while CS is low is greater or less than 16, the shift regis-ter contains only the last 16 bits, regardless of when they were entered. For the MAX4823, if the number of data bits entered while CS is low is greater or less than 8, the shift register contains only the last 8 data bits,regardless of when they were entered.Parallel Interface (MAX4824/MAX4825)The parallel interface consists of 3 address bits (A0,A1, A2) and one level selector bit (LVL). The address bits determine which output is updated, and the level bit determines whether the addressed output is switched on (LVL = high) or off (LVL = low). When CS is high, the address and level bits have no effect on the state of the outputs.

Address data entered after CS is pulled low is not reflected in the state of the outputs following the next low-to-high transition on CS (Figure 7).SET/RESET FunctionsThe MAX4822–MAX4825 feature set and reset inputs that allow simultaneous turn-on or turn-off of all outputs using a single control line. Drive SET low to set all latch-es and registers to 1 and turn all outputs on. SET over-rides all serial/parallel control inputs. Drive RESET low to clear all latches and registers and to turn all outputs off. RESET overrides all other inputs including SET .Power-On ResetThe MAX4822–MAX4825 feature power-on reset. The power-on reset function causes all latches to be cleared automatically upon power-up. This ensures that all outputs come up in the off or high-impedance state.Applications InformationDaisy ChainingThe MAX4822/MAX4823 feature a digital output (DOUT) that provides a simple way to daisy chain multi-ple devices. This feature allows driving large banks of relays using only a single serial interface. To daisy chain multiple devices, connect all CS inputs together,and connect the DOUT of one device to the DIN of another device (see Figure 8). During operation, a stream of serial data is shifted through the MAX4822/MAX4823 devices in series. When CS goes high, all outputs update simultaneously.The MAX4822/MAX4823 can also be used in a slave configuration that allows individual addressing of devices. Connect all the DIN inputs together, and usethe CS input to address one device at a time. Drive CS low to select a slave and input the data into the shift register. Drive CS high to latch the data and turn on the appropriate outputs. Typically, in this configuration only one slave is addressed at a time.Power-Save ModeThe MAX4822/MAX4824 feature a unique power-save mode where the relay current, after activation, can be reduced to a level just above the relay hold-current threshold. This mode keeps the relay activated while significantly reducing the power consumption.In serial mode (MAX4822), choose between seven cur-rent levels ranging from 30% to 90% of the nominal cur-rent in 10% increments. The actual percentage is determined by the power-save configuration register (Figure 1).In parallel mode (MAX4824), the power-save current is fixed at 60% of the nominal current.Power-Save TimerEvery time there is a write operation to the device (CS transitions from low to high), the MAX4822/MAX4824start charging the capacitor connected to PSAVE. The serial power-save implementation is such that a write operation does not change the state of channels already in power-save mode (unless the write turns the channel OFF).After a certain time period, t PS (determined by the capacitor value), the capacitor reaches a voltage threshold that sets all active outputs to power-save mode. The t PS period should be made long enough to allow the relay to turn on completely. The time period t PS can be adjusted by using different capacitor valuesRecovery Time and Power-Save Mode 12______________________________________________________________________________________Figure 5. 3-Wire Serial-Interface Operation for MAX4822connected to PSAVE. The value t PS is given by the fol-lowing formula:t PS = 32 x Cwhere C is in µF and t PS is in ms.For example, if the desired t PS is 20ms, then the required capacitor value is 20 / 32 = 0.625µF.Power-Save Mode AccuracyThe current through the relay is controlled by setting the voltage at OUT_ to a percentage of the V CC supply as specified under the Electrical Characteristics and in the register description. The current through the relay (I OUT )depends on the switch on-resistance, R ON,in addition to the relay resistance R R according to the fol-lowing relation:I OUT = V CC / (R ON + R R )The power-save, current-setting I PS depends on the fraction αof the supply voltage V CC that is set by the loop depending on the following relation:I PS = V CC - (αx V CC ) / R RTherefore:I PS / I OUT = (1- α) x (1 + R ON / R R )This relation shows how the fraction of reduction in the current depends on the switch on-resistance, as well as from the accuracy of the voltage setting (α). The higher the R ON with respect to R R, the higher the inaccuracy.This is particularly true at low voltage when the relay resistance is low (less than 40Ω) and the switch can account for up to 10% of the total resistance. In addi-tion, when the supply-voltage setting (α) is low (10% or 20%) and the supply voltage (V CC ) is low, the voltage drop across the switch (I OUT x R ON ) may already exceed, or may be very close to, the desired voltage-setting value.Daisy Chaining and Power-Save ModeIn a normal configuration using the power-save feature,several MAX4822s can be daisy chained as shown in Figure 9. For each MAX4822, the power-save timing t PD (time it takes to reduce the relay current once the relay is actuated) is controlled by the capacitor con-nected to PSAVE.An alternative configuration that eliminates the PSAVE capacitors uses a common PSAVE control line driven by an open-drain n-channel MOSFET (Figure 10). In this con-figuration, the PSAVE inputs are connected together to asynchronously control the power-save timing for all the MAX4822s in the chain. The µC/µP drives the n-channel MOSFET low for the duration of a write cycle to the SPI chain, plus some delay time to allow the relays to close.(This time is typically specified in the relay data sheet.)Once this delay time has elapsed, the n-channel MOSFET is turned off, allowing the MAX4822’s internal 35µA pullup current to raise PSAVE to a logic-high level, activating the power-save mode in all active outputs.MOSFET SelectionIn the daisy-chain configuration of Figure 10, the n-channel MOSFET drives PSAVE low. When the n-channel MOSFET is turned off, PSAVE is pulled high by an internal 35µA pullup in each MAX4822, and the power-save mode is enabled. Because of the paralleled PSAVE pullup currents, the required size of the n-channel MOSFET depends upon the number of MAX4822 devices in the chain. Determine the size of the n-channel MOSFET by the following relation:R ON < 1428 / NMAX4822–MAX4825Recovery Time and Power-Save Mode______________________________________________________________________________________13Figure 6. 3-Wire Serial-Interface Operation for the MAX4823Figure 7. Parallel-Interface Timing DiagramM A X 4822–M A X 4825where N is the total number of MAX4822 devices in a single chain, and R ON is the on-resistance of the n-channel MOSFET in Ωs.For example, if N = 10:R ON < 142ΩAn n-channel MOSFET with R ON less than 142Ωis required for a daisy chain of 10 MAX4822 devices.Inductive Kickback Protection withFast Recovery TimeThe MAX4822–MAX4825 feature built-in inductive kick-back protection to reduce the voltage spike on OUT_generated by a relay’s coil inductance when the output is suddenly switched off. An internal Zener clamp allows the inductor current to flow back to ground. The Zener configuration significantly reduces the recovery time (time it takes to turn off the relay) when compared to protection configurations with just one diode across the coil.Recovery Time and Power-Save Mode 14______________________________________________________________________________________Figure 9.

General DescriptionThe MAX4832/MAX4833 family of low-dropout (LDO)linear regulators feature an accurate current-limiting switch with an integrated FLAG or RESET function. These devices operate from 2.5V to 5.5V and deliver up to 100mA of load current at a preset output voltage. Preset output voltage levels are 1.8V/2.5V/2.8V/3.0V/3.3V.The MAX4832/MAX4833 offer a programmable soft-start control function to eliminate false reset during startup. The MAX4832 provides a FLAG function to noti-fy the system when the load current exceeds the limit.The MAX4833 provides a RESET function to notify the system when the output drops below the threshold.Additionally, reverse-current protection prevents cur-rent flowing from the output to the input. Other features include a low 90µA quiescent current, a 0.1µA shut-down current.The MAX4832/MAX4833 are available in space-saving 6-pin SOT23 and TDFN packages. Each device is speci-fied over the -40°C to +85°C extended temperature range. Contact factory for other programmed output volt-age versions from 1.5V to 3.3V in 100mV increments.For pin-compatible 250mA versions of this device, refer to the MAX4834/MAX4835. For pin-compatible 500mA versions of this device, refer to the MAX4836/MAX4837.ApplicationsSDIO Ports and Devices Notebook Computers USB Ports and Devices Cell Phones PDAs and Palmtop DevicesGPS SystemsFeatures♦Guaranteed Minimum 100mA Load Current♦Accurate Current Limit♦Preset Output Voltages: 1.8V/2.5V/2.8V/3.0V/3.3V ♦2.5V to 5.5V Supply Voltage Range ♦Adjustable Soft-Start ♦Low Dropout Voltage ♦Thermal Shutdown♦Reverse-Current Protection♦Shutdown Output Discharge (MAX4833)♦Low 90µA Supply Current♦Ultra-Low 0.1µA Shutdown Current ♦FLAG and Latch Off (MAX4832) or RESET (MAX4833)♦Tiny SOT23 and TDFN PackagesMAX4832/MAX4833100mA LDO Linear Regulators withCurrent-Limiting Switch________________________________________________________________Maxim Integrated Products1Ordering Information19-3372; Rev 0; 7/04For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .devices.

Limits across the full temperature range are guaranteed by design and correlation over thespecified temperature range.Note 2:The dropout voltage is measured from V IN to V OUT when V OUT is 2% below its nominal value. The nominal output voltage ismeasured from V OUT to GND when V IN is 1V greater than V OUT . Defined only for V OUT ≥2.5V.Note 3:Soft-start time is defined as the time required for the output to rise from 10% of its nominal value to 90% of its nominal value.Note 4:For V OUT < 2V, V IN must be above 2.5V.Note 5:This is the maximum time OUT can be out of tolerance before a reset is issued. It is implemented to ensure that momentaryoutput glitches do not trigger a reset condition.Note 6:In startup mode, the blanking time counter is not started until the soft-start time has elapsed.

These devices guarantee up to 100mA drive capabilities and regulate the preset output voltage.The MAX4832 has a flag output that asserts low when the load current exceeds the current limit for more than the blanking time (t BLANK). The MAX4833 has a reset output that asserts low when the regulator output volt-age is below the reset threshold voltage (V RESET). V RESET is 87.5% of the nominal output voltage. Figure 1 shows the simplified functional diagram and Figure 2 shows the typical application circuits.FLAG Output (MAX4832) The open-drain FLAG output goes low and the LDO’s pass transistor is latched off when the current in the pass transistor is at its output current limit for more than the blanking time (t BLANK). Cycling IN, or SHDN(high to low to high) brings the device out of its latched-off state and back into normal operation.RESET Output (MAX4833)The RESET output asserts when one of the following conditions occurs:•The input voltage (V IN) is below the input undervolt-age lockout threshold (V UVLO).•The output voltage (V OUT) is below the reset thresh-old (V RESET).•SHDN is pulled low.•The device is in thermal shutdown.•When V OUT> V IN.RESET remains low for the reset timeout period (t RESET)after reset conditions are terminated. There are four RESET timeout periods available as shown in the Electrical Characteristics table. RESET is available in apush-pull configuration as shown in the Selector Guide.ShutdownPull SHDN low to shut down the LDO and reduce the quiescent current consumption of the device from 90µAto 0.1µA. In shutdown mode, the pass transistor, con-trol circuit, and reference circuit are turned off. Connect SHDN to a supply voltage greater than V IH to turn onthe LDO.MAX4832/MAX4833100mA LDO Linear Regulators withCurrent-Limiting Switch _______________________________________________________________________________________7M A X 4832/M A X 4833100mA LDO Linear Regulators with Current-Limiting Switch 8_______________________________________________________________________________________Figure 2. Typical Application CircuitsShutdown Discharge (MAX4833) OUT discharges through a 900Ωinternal resistor during shutdown mode.Reverse OUT to IN Current When the output voltage is greater than the input volt-age, the internal pass transistor turns off. To avoid reverse-charging the input source, the current at IN is guaranteed to be below 3µA when V OUT≥V IN.Current Limit The MAX4832/MAX4833 include an accurate internal current-limiting circuit. OUT can be shorted to ground indefinitely without damaging the part.The MAX4832 latches off if the load current exceeds the current limit for more than the blanking time (see the FLAG Output section). During soft-start, the device does not latch off to an overload condition. During an overload condition, the MAX4833 holds the current at current limit until the thermal limit is reached. Once the junction tem-perature reaches +165°C, thermal shutdown occurs.Thermal Shutdown When the junction temperature (T J) exceeds +165°C, the LDO’s pass transistor turns off allowing the junction to cool. The LDO’s pass transistor turns on again after the IC’s junction temperature cools by 15°C, resulting in a pulsed output during continuous thermal-overload conditions.Soft-Start During power-up, the soft-start ensures that the output ramps up slowly reducing inrush current peaks. See the soft-start response time plots in the Typical Operating Characteristics. The soft-start time (t SS) is given by the following equation:t SS= C SS(ms)where C SS is in nF.A soft-start capacitor (C SS) of 10nF gives a 10ms t SS. A 1ms minimum soft-start time is fixed internally to ensure that the output rises slowly even without any external capacitor at SS pin to ground. The device is in soft-start mode when either the voltage at IN or SHDN is cycled high to low to high.Applications InformationCapacitor Selection and RegulatorStabilityFor stable operation over the full temperature range andwith load currents up to 100mA, use a 3.3µF (min) ceramic output capacitor with an ESR <0.2Ω. To reducenoise and improve load transient response, stability, and power-supply rejection, use larger output capacitor values such as 10µF (note that some ceramic capacitors exhibit large capacitance and ESR variation with temper-ature). X7R capacitors provide good performance overthe -40°C to +85°C operating temperature range.To improve power-supply rejection and transient response, use a 0.1µF capacitor between IN and GND.The MAX4832/MAX4833 remain stable with purely resistive loads or current loads up to 100mA.15kV Operational ESD ProtectionA 3.3µF or higher value ceramic capacitor from OUT toGND provides a 15kV (Human Body Model) protectionat OUT. The ESR value of the capacitor should be lessthan 0.2Ω.Reset Transient ImmunityThe reset circuit is relatively immune to short duration,falling V OUT transients. The Typical Operating Characteristics show a graph of the Maximum Transient Duration vs. Reset Threshold Overdrive for which reset isnot asserted. The graph was produced using falling V OUT transients starting at V OUT and ending below the reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maximum pulse widththat a falling V OUT transient can typically have without triggering the reset pulse. As the amplitude of the tran-sient increases (i.e., goes further below the reset thresh-old), the maximum allowable pulse width decreases. Typically, a V OUT transient that goes only 10mV below thereset threshold and lasts up to 54µs does not trigger areset pulse.LayoutWhen using the TDFN package, connect its exposed paddle to G ND to provide a low thermal resistancepath for heat transfer from the IC junction to the printedcircuit board.MAX4832/MAX4833100mA LDO Linear Regulators withCurrent-Limiting Switch _______________________________________________________________________________________9M A X 4832/M A X 4833100mA LDO Linear Regulators with Current-Limiting Switch 10______________________________________________________________________________________Table 1.
