General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, andMAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and onereceiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize E MI andreduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them totransmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA ofsupply current when unloaded or fully loaded with disableddrivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consumeonly 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermal shutdowncircuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature thatguarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-loadreceiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, whilethe MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________Applications Low-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level Translators Transceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features o For Fault-Tolerant Applications MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 Transceiver MAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers o For Space-Constrained Applications MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 Transceivers MAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 Package MAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe Receivers MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-485/RS-422 Transmitters o For Multiple Transceiver Applications MAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters o For Fail-Safe Applications MAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceiverso For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kVESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 Transceivers For pricing, delivery, and ordering information, please contact Maxim Direct at1-888-629-4642, or visit Maxim Integrated’s website at .______________________________________________________________Selection Table19-0122; Rev 10; 9/14PARTNUMBERHALF/FULL DUPLEX DATA RATE (Mbps) SLEW-RATE LIMITED LOW-POWER SHUTDOWN RECEIVER/DRIVER ENABLE QUIESCENT CURRENT (μA) NUMBER OF RECEIVERS ON BUS PIN COUNT MAX481Half 2.5No Yes Yes 300328MAX483Half 0.25Yes Yes Yes 120328MAX485Half 2.5No No Yes 300328MAX487Half 0.25Yes Yes Yes 1201288MAX488Full 0.25Yes No No 120328MAX489Full 0.25Yes No Yes 1203214MAX490Full 2.5No No No 300328MAX491Full 2.5No No Yes 3003214MAX1487 Half 2.5No No Yes 2301288Ordering Information appears at end of data sheet.找电子元器件上宇航军工MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-LimitedRS-485/RS-422 TransceiversPackage Information For the latest package outline information and land patterns, go to .

MAX541

MAX541是美国MAXIM公司生产的D/A转换芯片，它是低功耗（1.5mW），无缓冲电压输出，能够驱动60kv的负载，用单+5V电源工作的串行16位数模转换器。

其转换时间为1μs，输出电压变换范围为0V~VREF[16]。

下图为芯片的管脚图，并将MAX541的管脚功能列于表3-3中。

MAX的工作原理是：模拟输出电压VOUT的输出范围由输入不同的数字代码来有规律的控制，当输入的16位数字代码全为0时，输出电压VOUT为0。

当输入的16位数字代码全为1时，输出电压约为VREF即2.5V。

于是VOUT的变化规律是，16位数字代码从0开始，每次加1，一直到全为1，对应的输出电压一直从0开始每次增加VREF*(1/65536)。

MEMORY存储芯片MAX125CEAX+D中文规格书

General DescriptionThe MAX125/MAX126 are high-speed, multichannel,14-bit data-acquisition systems (DAS) with simultaneous track/holds (T/Hs). These devices contain a 14-bit, 3µs,successive-approximation analog-to-digital converter (ADC), a +2.5V reference, a buffered reference input,and a bank of four simultaneous-sampling T/H ampli-fiers that preserve the relative phase information of the sampled inputs. The MAX125/MAX126 have two multi-plexed inputs for each T/H, allowing a total of eight inputs. In addition, the converter is overvoltage tolerant to ±17V; a fault condition on any channel will not harm the I C. Available input ranges are ±5V (MAX125) and ±2.5V (MAX126).An on-board sequencer converts one to four channels per CONVST pulse. In the default mode, one T/H output (CH1A) is converted. An interrupt signal (INT ) is provided after the last conversion is complete. Convert two,three, or four channels by reprogramming the MAX125/MAX126 through the bidirectional parallel interface. Once programmed, the MAX125/MAX126continue to convert the specified number of channels per CONVST pulse until they are reprogrammed. The channels are converted sequentially, beginning with CH1. The INT signal always follows the end of the last conversion in a conversion sequence. The ADC con-verts each assigned channel in 3µs and stores the result in an internal 14x4 RAM. Upon completion of the conversions, data can be accessed by applying suc-cessive pulses to the RD pin. Four successive reads access four data words sequentially.The parallel interface’s data-access and bus-release timing specifications are compatible with most popular digital signal processors and 16-bit/32-bit microproces-sors, so the MAX125/MAX126 conversion results can be accessed without resorting to wait states.ApplicationsMultiphase Motor Control Power-Grid Synchronization Power-Factor Monitoring Digital Signal Processing Vibration and Waveform AnalysisFeatures♦Four Simultaneous-Sampling T/H Amplifiers with Two Multiplexed Inputs (eight single-ended inputs total)♦3µs Conversion Time per Channel ♦Throughput: 250ksps (1 channel)142ksps (2 channels)100ksps (3 channels)76ksps (4 channels)♦Input Range: ±5V (MAX125)±2.5V (MAX126)♦Fault-Protected Input Multiplexer (±17V)♦±5V Supplies♦Internal +2.5V or External Reference Operation ♦Programmable On-Board Sequencer ♦High-Speed Parallel DSP InterfaceMAX125/MAX126________________________________________________________________Ordering InformationTypical Operating Circuit appears at end of data sheet.Pin Configuration appears at end of data sheet.PART TEMP RANGE PIN-PACKAGEINL(LSB) MAX125CCAX 0°C to +70°C 36 SSOP ±4 MAX125CEAX -40°C to +85°C 36 SSOP ±4 MAX126CCAX 0°C to +70°C 36 SSOP ±4 MAX126CEAX-40°C to +85°C36 SSOP±4_______________Detailed DescriptionThe MAX125/MAX126 use a successive-approximation conversion technique and four simultaneous-sampling track/hold (T/H) amplifiers to convert analog signals into 14-bit digital outputs. Each T/H has two multiplexed inputs, allowing a total of eight inputs. Each T/H output is converted and stored in memory to be accessed sequentially by the parallel interface with successive read cycles. The MAX125/MAX126 internal micro-sequencer can be programmed to digitize one, two,three, or four inputs sampled simultaneously from either of the two banks of four inputs (see Figure 2).The conversion timing and control sequences are derived from a 16MH z external clock, the CONVSTM A X 125/M A X 1262x4-Channel, Simultaneous-Sampling 14-Bit DAS______________________________________________________________Pin DescriptionMAX125/MAX12614-Bit DAS_______________________________________________________________________________________Figure 2.Functional Diagram1ppm/°C (max) temperature drift. Connect an external reference at REFIN as shown in Figure 7. The minimum impedance is 7kΩfor DC currents in both normal oper-ation and shutdown. Bypass REFOUT with a 4.7µF low-ESR capacitor.Power-On Reset When power is first applied, the internal power-on-reset circuitry activates the MAX125/MAX126 with INT= high, ready to convert. The default conversion mode is Input Mux A/Single-Channel Conversion. See the Programming Modes section if other configurations are desired.After the power supplies have been stabilized, the reset time is 5µs; no conversions should be performed during this phase. At power-up, data in memory is undefined.Software Power-Down Software power-down is activated by setting bit A3 of the control word high (Table 1). It is asserted after the WR or CS rising edge, at which point the ADC immedi-ately powers down to a low quiescent-current state. AV DD drops to less than 1.5mA, and AV SS is reduced to less than 1mA. The ADC blocks and reference buffer are turned off, but the digital interface and the refer-ence remain active for fast power-up recovery. Wake up the MAX125/MAX126 by writing a control word (A0–A3, Table 1). The bidirectional interface interprets a logic zero at A3 as the start signal and powers up in the mode selected by A0, A1, and A2. The referencebuffer’s settling time and the bypass capacitor’s value dominate the power-up delay. With the recommended 4.7µF at REFOUT, the power-up delay is typically 5µs.Transfer Function The MAX125/MAX126 have bipolar input ranges. Fig-ure 8 shows the bipolar/output transfer function. Code transitions occur at successive-integer least significant bit (LSB) values. Output coding is twos-complement binary with 1LSB = 610µV for the MAX125 and 1LSB = 305µV for the MAX126.Output Demultiplexer An output demultiplexer circuit is useful for isolating data from one channel in a four-channel conversion sequence. Figure 9’s circuit uses the external 16MH z clock and the INT signal to generate four RD pulses and a latch clock to save data from the desired chan-nel. CS must be low during the four RD pulses. The channel is selected with the binary coding of two switches. A 16-bit 16373 latch simplifies layout.Motor-Control Applications Vector motor control requires monitoring of the individ-ual phase currents. In their most basic application, the MAX125/MAX126 simultaneously sample two currents (CH1A and CH2A, Figure 10) and preserve the neces-sary relative phase information. Only two of the three phase currents have to be digitized, because the third component can be mathematically derived with a coor-dinate transformation.MAX125/MAX12614-Bit DAS______________________________________________________________________________________ Figure 7.External Reference Figure 8.

MAX1501ZETE中文资料

General DescriptionThe MAX1501 intelligent, constant-current, constant-voltage (CCCV), temperature-regulated battery charger charges a single lithium-ion (Li+) cell or three-cell NiMH/NiCd batteries. The device integrates the current-sense resistor, PMOS pass element, and thermal-regulation circuitry, while eliminating the reverse-blocking Schottky diode to create the simplest charging solution for hand-held equipment.The MAX1501 functions as a stand-alone charger to control the charging sequence from the prequalification state through fast charge, top-off, and charge termination for single-cell Li+ or three-cell NiMH/NiCd batteries.Alternatively, the MAX1501 collaborates with a host microprocessor to determine the best charging algorithm.Proprietary thermal-regulation circuitry limits the die temperature when fast charging or while exposed to high ambient temperatures, allowing maximum charging current without damaging the charger. The MAX1501 continually supplies a regulated output voltage under no-battery conditions, allowing battery changing.The device achieves high flexibility by providing an adjustable fast-charge current, top-off current, safety timer (disabled in the MAX1501Z), and thermal-regula-tion setpoint. Other features include input power detec-tion (ACOK ) and input under-/overvoltage protection.The MAX1501 provides active-low control inputs.The MAX1501 accepts a 4.5V to 13V supply, but disables charging when the input voltage exceeds 6.5V, preventing excessive power dissipation. The MAX1501 operates over the extended temperature range (-40°C to +85°C) and is available in a compact 16-pin thermally enhanced 5mm x 5mm thin QFN package with 0.8mm profile.ApplicationsCellular and Cordless Phones PDAsDigital Cameras and MP3 Players USB AppliancesCharging Cradles and Docks Bluetooth™ EquipmentFeatures♦Stand-Alone or Microprocessor-Controlled (µP)Linear 1-Cell Li+ or 3-Cell NiMH/NiCd Battery Charger ♦No FET, Reverse-Blocking Diode, or Current-Sense Resistor Required♦ 1.4A (max) Programmable Fast-Charge Current ♦+95°C, +115°C, and +135°C ProprietaryProgrammable Die Temperature Regulation Control♦ 4.5V to 13V Input Voltage Range with Input Overvoltage (OVLO) Protection Above 6.5V♦Programmable Top-Off Current Threshold: 10%,20%, or 30% of the Fast-Charge Current ♦Charge-Current Monitor for Fuel Gauging♦Programmable Safety Timer (3, 4.5, or 6 hours)♦Input Power Detection Output (ACOK ) and Charge Enable Input (CHGEN )♦Automatic Recharge♦Digital Soft-Start Limits Inrush Current♦Charge Status Outputs for LEDs or µP InterfaceMAX1501Highly Integrated, Linear Battery Charger with Thermal Regulation for Portable Applications________________________________________________________________Maxim Integrated Products 1Ordering Information19-2800; Rev 1; 3/04For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Pin Configuration appears at end of data sheet.Typical Operating CircuitBluetooth is a trademark of Ericsson.M A X 1501Thermal Regulation for Portable Applications 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V IN = V INP = 5V, V BATT = 3.5V, ACOK = GLED = RLED = TEMP = TMAX/I.C. = FULLI = open, CHGEN = MODE = GND, R SETI = 2.8k Ω,C IN = 1µF, C BATT = 10µF, T A = 0°C to +85°C , unless otherwise noted.

Both inputs possess internal 175k Ωpulldown resistors to GND. Table 1 describes the four operating modes of the MAX1501.MAX1501Thermal Regulation for Portable Applications______________________________________________________________________________________11Li+ Charge ModeConnect CHGEN and MODE to GND to place the MAX1501 in Li+ charging mode. The Li+ charger con-sists of a voltage-control loop, a current-control loop,and a thermal-control loop. Connect SELV to GND to set the Li+ battery voltage to 4.1V. Connect SELV to VL to set the Li+ battery voltage to 4.2V (Table 2).The MAX1501 precharges the Li+ battery with 10% of the user-programmed fast-charge current at the start of a charge cycle. A soft-start algorithm ramps up the charging current (10% steps with 20ms duration per step) to the fast-charge current when the battery volt-age reaches 2.8V. The MAX1501 enters constant-volt-age mode and decreases the charge current when the BATT voltage reaches the selected regulation voltage (4.1V or 4.2V). Set the fast-charge current with a resis-tor between SETI and GND (see the Charge-Current Selection section).The thermal-regulation loop limits the MAX1501 die temperature to the value selected by the TEMP input by reducing the charge current as necessary (see the Thermal-Regulation Selection section). This feature not only protects the MAX1501 from overheating, but also allows the charge current to be set higher without risking damage to the system.Set the top-off-current threshold with the three-state FULLI input (see the Top-Off-Current Selection section).RLED goes high impedance and GLED asserts low when the top-off-current threshold is reached. The MAX1501automatically initiates recharging when the battery volt-age drops below 95% of the voltage set by SELV. (The MAX1501Z does not time out.)NiMH/NiCd Charge ModeConnect CHGEN to GND and MODE to VL to place the MAX1501 in NiMH/NiCd charging mode. The NiMH/NiCd battery charger consists of a current-control loop, a volt-age-control loop, and a thermal-control loop. Connect SELV to GND to set the regulation voltage to 4.5V.Connect SELV to VL to set the regulation voltage to 4.95V (Table 2). When charging three NiMH/NiCd cells to 4.95V, V IN must be at least 5.25V and a µP must be used to terminate the charge sequence.Table 2. Battery Regulation VoltageFigure 4. Li+ Charge SequenceM A X 1501Thermal Regulation for Portable Applications 1210% of the user-programmed fast-charge current at the start of a charge cycle. Precharge ends and fast charge begins when the battery voltage exceeds 2.8V.Set the fast-charge current with a resistor between SETI and GND (see the Charge-Current Selection section).The MAX1501 enters constant-voltage mode and decreases the charge current when the battery voltage reaches 4.5V.The thermal-regulation loop limits the MAX1501 die temperature to the value selected by the TEMP input by reducing the charge current as necessary (see the Thermal-Regulation Selection section). This feature pro-tects the MAX1501 from overheating when supplying high charge currents, or while operating from high input voltages.Set the top-off-current threshold with the three-state FULLI input (see the Top-Off-Current Selection section).RLED goes high impedance and GLED asserts low when the top-off current threshold is reached. The MAX1501 automatically initiates recharging when the battery voltage drops below 4V. (The MAX1501Z does not time out.)No-Battery ModeConnect CHGEN and MODE to VL to place the MAX1501in no-battery mode. An external load can be connected to BATT in this mode. V BATT regulates to 4V in no-battery mode, regardless of the state of SELV.The current-control loop, voltage-control loop, and thermal-control loop all function in no-battery mode.The loop gain of the voltage-control loop decreases to ensure stability with no battery present. Connect a 10µF ceramic capacitor to BATT for stability. RLED and GLED are both high impedance in no-battery mode.ACOKThe ACOK output asserts low when V IN is present, 4.2V ≤V IN ≤6.25V, and V IN - V BATT > 100mV. The ACOK open-drain output requires an external 100k Ωpullupsupply voltage must be less than 5.5V.RLED and GLED IndicatorsRLED and GLED serve as visual indicators that power is applied as well as the charge status of a battery.RLED asserts low when a wall adapter is connected and a battery is charging, regardless of cell chemistry.GLED asserts low when power is applied and the bat-tery is fully charged. Both outputs go high-impedance in shutdown. Connect the anode of each LED to IN,and the cathode to RLED or GLED . Table 3 summa-rizes the behavior of RLED and GLED under normal operating conditions. Connect pullup resistors to the µP I/O supply when interfacing RLED and GLED with a µP’s logic inputs.Soft-StartA ten-step, soft-start algorithm activates when entering fast-charge mode. The charging current ramps up in 10% increments, 20ms per step, to the full charging current when V BATT exceeds 2.8V.Applications InformationCharge-Current SelectionProgram the charging current using an external resistor between SETI and GND. Set the charge-current resistor with the following equation:If V SETI = 1.4V, the current-control loop controls the battery charging. If V SETI < 1.4V, either the voltage-control loop or the thermal-control loop operates.Measure the charging current by monitoring V SETI and using the following equation:MAX1501Thermal Regulation for Portable Applications______________________________________________________________________________________13Thermal-Regulation SelectionSet the regulated die temperature of the MAX1501 with the TEMP three-level logic input. The MAX1501reduces the charge current to limit the die temperature to the value set by TEMP. The MAX1501 operates nor-mally while the thermal loop is active. An active thermal loop does not indicate a fault condition. TEMP allows the MAX1501 to maximize the charge current while pro-viding protection against excessive power dissipation.Connect TEMP to GND to regulate the die temperature at +95°C. Leave TEMP floating to regulate the die tem-perature at +115°C. Connect TEMP to VL to regulate the die temperature at +135°C.Top-Off-Current SelectionSet the top-off-current threshold in the Li+ and NiMH/NiCd charge modes with the FULLI three-level logic input. The top-off-current threshold determines when RLED turns off and GLED turns on, indicating the charge status of the battery.Connect FULLI to GND to set the top-off-current thresh-old to 10% of the fast-charge current. Connect FULLI to VL to set the top-off-current threshold to 20% of the fast-charge current. Leave FULLI floating to set the top-off-current threshold to 30% of the fast-charge current.Charge-Timer Selection (MAX1501 Only)Set the maximum charging time with the TMAX three-level logic input. TMAX limits the duration of charging to protect the battery from overcharging. Connect TMAX to GND to set the maximum charging time to 3 hours.Leave TMAX floating to set the maximum charging timeto 4.5 hours. Connect TMAX to VL to set the maximum charging time to 6 hours.Capacitor SelectionConnect a ceramic capacitor from BATT to GND for proper stability. Use a 10µF X5R ceramic capacitor for most applications.Connect IN and INP together and bypass to GND with a 1µF ceramic capacitor. Use a larger input bypass capacitor for high input voltages or high charging cur-rents to reduce supply noise.Thermal ConsiderationsThe MAX1501 is available in a thermally enhanced thin QFN package with exposed paddle. Connect the exposed paddle of the MAX1501 to a large copper ground plane to provide a thermal contact between the device and the circuit board. The exposed paddle transfers heat away from the device, allowing the MAX1501 to charge the battery with maximum current,while minimizing the increase in die temperature.Application CircuitsFigure 5 shows the MAX1501 as a stand-alone Li+ bat-tery charger. The 2.8k Ωresistor connected to SETI sets a charging current of 500mA.Figure 6 shows the MAX1501 as a µP-based Li+ battery charger. Drive CHGEN low to charge the battery. Drive CHGEN high to disable the charger. Connect a 100k Ωpullup resistor from ACOK to the logic supply voltage of the µP to detect the presence of an input supply.

3.9Replacing and Handling the BatteryThe 545–1105/1106 and 555–1105/1106 CPUs use a lithium battery formaintaining CPU memory contents while power is not present. The lithium battery is a primary cell; it is not rechargeable. The battery in these CPU models is accessible through the bezel door on the front of the module, as shown in Figure 3-9.When the battery indicator blinks or goes off, the battery has dropped below the voltage required to maintain memory and should be replaced. Request battery kit replacement part number PPX:2587678-8005 for the appropriate replacement battery. Refer to page 3-19 for guidelines on handling batteries.NOTE: As a good engineering practice, design your user program to monitor Status Word 01 on a cyclic basis and trigger an alarm if the battery-low bit (15) is set. Additionally, you can use the battery life specifications listed in Table A-2 to determine how often you routinely replace the battery.Figure 3-9Battery Location in –1105 and –1106 CPU ModulesLithium Battery in the 545 and 555–1105/–1106 CPUsFollow these steps to replace the battery:1.Maintain power to the CPU.2.Open the battery cover.3.Pull out the old battery and disconnect the battery connectors.4.Connect the battery connectors to the replacement battery.5.Place the new battery in the battery compartment, making sure the connecting wires are fully inserted through the holes in the compartment, and close the cover.6.Check the BATT GOOD indicator on the CPU to make sure that it lights back up to confirm that the replacement battery is good.Figure 3-10Replacing the Battery in –1105 and –1106 CPU ModulesReplacing the Battery in–1105/–1106 CPUsReplacing and Handling the Battery (continued)The 545–1103/1104 and 555–1103/1104 CPUs use a lithium coin battery for maintaining CPU memory contents while power is not present. The battery is a Panasonic BR2325, PPX:2587678–8010, or equivalent, 23 mm diameter,with a nominal capacity of 165 mAh. The lithium battery is a primary cell;it is not rechargeable. Figure 3-11 shows the location of the battery on the CPU card.Figure 3-11Battery Location on 545/555 CPU ModulesA fresh battery can typically maintain your system with power off for three months at room temperature, or a substantially shorter time at elevated temperatures. The battery indicator is illuminated as long as power is present and the battery voltage is adequate for maintaining the memory;however, the indicator does not show the amount of battery life remaining.When the battery indicator blinks or goes off, the battery has dropped below the voltage required to maintain memory and should be replaced. See page 3-20, “Replacing the Battery.”Lithium Battery in the 545 and 555–1103/–1104 CPUsIndicatorsUse the following safety instructions to minimize the risk of personal injury or fire hazard when handling lithium batteries.Lithium batteries contain flammable material. Do not open, puncture, or crush the battery case. Puncturing the battery case releases electrolyte and potentially flammable material. Exposure to electrolyte can cause throat and/or eye irritation. If the electrolyte comes in contact with your skin or eyes, flush the area thoroughly with large amounts of water.Never use a lithium battery in a completely sealed container. Containers must have a mechanism for relieving pressure if the battery is exposed to high temperature or abuse.If a lithium battery short-circuits, disconnect it immediately and move it to a well-ventilated area. Wear safety glasses and other protective gear when handling a disabled battery.Transportation of lithium batteries is regulated by the U.S. Department of Transportation. Lithium batteries must be shipped under exemption DOT –E 7502.•For international shipments, IATA Regulation 2294 applies.•Lithium batteries such as the one used in the 545 and 555 CPUs, which contains less than 0.5 grams of lithium, are not restricted in shipment,according to DOT 173.206 (f) or IATA Section X.Take precautions in storing batteries.•Do not place batteries on a metal surface; doing so could cause a potential short circuit.•Do not store batteries loosely or in dump bins. Store batteries in the original shipping container.•Store batteries in a cool, well-ventilated area with a maximum temperature of 70°C (158°F).Batteries to be discarded may contain a significant amount of unusedenergy. They must be packed for disposal and isolated electrically. Batteries must be disposed of in accordance with all local, state and federal regulations.Using and Handling BatteriesTransporting BatteriesStoring Batteries Discarding BatteriesReplacing and Handling the Battery (continued)ATTENTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer .Discard used batteries according to the manufacturer’s instructions.ATTENTION: Il y a danger d’explosion s’il y a remplacement incorrect de la batterie. Remplacer uniquement avec une batterie du même type ou d’un type recommandé par le constructeur . Mettre au rebut les batteries usagées conformement aux instructions du fabricant.** Canadian standard CAN/CSA C22.2, No. 950–M89Battery changes require advance planning. For the 545–1103/1104 and 555–1103/1104 CPUs, keep the following guidelines in mind: •In order to change the lithium battery, you must power down the system.•Memory can be lost if system power is removed from the CPU for longer than twenty minutes during a battery change.•A good battery must be in place when power is restored, or else the CPU goes through a battery-bad powerup and all memory is lost.NOTE: As a safeguard, consider using SoftShop, TISOFT, or APT to save your program before you replace the battery.Follow these steps to replace the lithium battery:1.Place your process in a safe state.2.Disconnect power from the chassis.At room temperature, you have approximately twenty minutes to replace the battery after power is removed from the CPU.If the CPU detects a bad battery before power is either removed or lost (e.g., power failure), you must replace the battery before restoring power, or lose memory contents.Replacing the Battery in–1103/–1104 CPUs3.Remove the CPU from the chassis and place the CPU, component-side up, on a static-dissipative surface.The components in the CPU card can be degraded or destroyed by electrostatic discharge (ESD). Follow proper handling precautions in order to prevent ESD damage.4.Remove the battery from the socket, observing the following precautions:•Use a non-conductive implement when removing the battery from the socket. Do not allow a conductive device (for example, a metal screwdriver blade) to contact both sides of the batterysimultaneously. Since the battery is shaped like a coin, it is easy for the screwdriver blade to make contact with both rim and underside, which would cause a short.•If you pull the battery straight up from the socket, you could spring the positive contact and ruin the socket. Instead, lift the battery up to the height of the socket rim and carefully slide it out,making certain you do not bend the socket ’s positive contact.5.Slide a fresh battery into the socket, being careful to observe polarity.The battery and the socket are both marked with plus signs (+),indicating positive contacts. The positive contact is the upper contact.6.Reinstall the CPU in the chassis.7.Ensure the battery is enabled (SW9 is set to On). (See page 3-22.)8.Restore power to the chassis.3.10Setting the CPU DipswitchesDipswitches are used to set 545/555 CPU operating parameters. The dipswitches are located near the front of the CPU, behind the bezel orbattery door. See Figure 3-12. To gain access, lower the access door. With the CPU in its (normal) vertical position, dipswitches pushed to the left are On;dipswitches pushed to the right are Off.Figure 3-12545/555 CPU Dipswitch LocationSwitch 9 is used to set the back-up battery On or Off. As Figure 3-12indicates, moving the switch to the left enables the back-up battery; setting the switch to the right disables the back-up battery.NOTE: When SW9 is set to the On position, the battery LED indicates the state of the battery back-up circuit. If the battery LED is illuminated,memory contents should be maintained; if the LED is not illuminated,memory contents will not be maintained.Switch 10 is used to allow the CPU to perform an Auto Recompile during runtime. Switch 10 is shipped in the disabled (left) position. To activate this feature, set the switch to the right (enabled) position. Refer to Appendix F for more information about the Auto Recompile function.Dipswitch Location and SettingsEnabling Battery BackupEnabling the Auto Recompile FunctionSetting Baud RatesSwitches 3 through 8 are used to set baud rates for Ports 1 and 2. Switches3, 4, and 5 set Port 1 baud rates. See Table 3-3. Switches 6, 7, and 8 set Port2 baud rates. See Table 3-4.Table 3-3Port 1 Baud Rate SettingsTable 3-4Port 2 Baud Rate SettingsNOTE: The baud rates 115,200 and 57,600 are available only on the555–1105 and 555–1106 CPUs.Setting the CPU Dipswitches (continued)The 545 and 555 CPUs have two communications ports. Both ports are configured as Data Terminal Equipment (DTE).SW2 selects Port 1 as either a programming port or a printer port on a 545/555 CPU. Port 1 uses an RS-232/RS-423 signaling protocol and an RS-232 pinout arrangement with an RS-423 (+5 V) signal level extending up to 50 feet (15 m). You can use a modem to extend this distance. •Setting SW2 to the left selects Port 1 as a programming port.•Setting SW2 to the right selects Port 1 as a printer port.Figure 3-13 shows the locations of Port 1 and Port 2 on the front of the CPU.Figure 3-13545/555 CPU Port LocationsWith the 545 and 555 CPUs, your choice of cabling determines whether Port 2 functions as an RS-232/RS-423 port or as an RS-422/RS-485 port.Figure 3-13 describes the pinouts required for the various Port 2 options.If you use RS-422/RS-485 cabling, SW1 on the dipswitch allows you to select between RS-422 and RS-485. Use SW1 as follows:•Set SW1 to the left when you use RS-232 or RS-422 cabling.•Set SW1 to to the right when you use RS-485 cabling. RS-485 uses a single twisted pair to transmit and receive data between theprogramming device and the 545/555 CPU. Multiple CPUs or multiple programming devices (on this RS-485 link) are not supported and must not be used.Communications Port 1Communications Port 2。

General DescriptionThe MAX5450–MAX5455 are a family of dual digital potentiometers that perform the same function as a mechanical potentiometer or variable resistor. The MAX5451/MAX5453/MAX5455 have two 3-terminal potentiometers and the MAX5450/MAX5452/MAX5454have two 2-terminal variable resistors. The MAX5450–MAX5455 operate from a +2.7V to +5.5V single-supply voltage and use an ultra-low supply current of 0.1µA.These devices consist of two fixed resistors each with 256 digitally-controlled wiper contacts. The conve-nient power-on reset (POR) sets the wiper to midscale position at power-up and the easy-to-use up/down interface allows glitchless switching between resistor taps. Six inputs control the 14-pin MAX5451/MAX5453/MAX5455 potentiometers. Four inputs control the 10-pin MAX5450/MAX5452/MAX5454 variable resis-tors.The MAX5450–MAX5455 are ideal for applications requiring digitally-controlled resistors. Three resistance values are available: 10k Ω, 50k Ω, and 100k Ω. An end-to-end resistor temperature coefficient of 35ppm/°C and a ratiometric temperature coefficient of 5ppm/°C make the MAX5450–MAX5455 excellent choices for adjustable gain circuit requiring low-temperature drift The MAX5450–MAX5455 are available in 10-pin µMAX ®and 14-pin TSSOP packages. Each device is guaran-teed over the extended–industrial temperature range (-40°C to +85°C).ApplicationsMechanical Potentiometer Replacement Low-Drift Programmable-Gain Amplifier (PGA)Volume Control LCD Screen Adjustment Adjustable Voltage References Adjustable Linear RegulatorsProgrammable Filters, Delays, Time Constants Impedance MatchingFeatures♦Small-Footprint Packages10-Pin µMAX (MAX5450/MAX5452/MAX5454)14-Pin TSSOP (MAX5451/MAX5453/MAX5455)♦256-Tap Positions♦Independent Up/Down Potentiometer Controls (MAX5451/MAX5453/MAX5455)♦Ultra-Low 0.1µA Supply Current ♦+2.7V to +5.5V Single-Supply Operation ♦Low 35ppm/°C End-to-End Temperature Coefficient ♦Power-On Reset Sets Wiper to Midscale (Position 127)♦Glitchless Switching Between the Resistor Taps ♦10k Ω, 50k Ω, 100k ΩResistance ValuesMAX5450–MAX5455Dual, 256-Tap, Up/Down Interface,Digital Potentiometers________________________________________________________________Maxim Integrated Products 1Pin Configurations19-1997; Rev 2; 2/06Ordering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .range.µMAX is a registered trademark of Maxim Integrated Products, Inc.M A X 5450–M A X 5455Dual, 256-Tap, Up/Down Interface,Digital PotentiometersABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Power-on reset cir-cuitry sets the wiper to midscale (position 127) at power-up.Logic inputs CS , U/D , and INC determine the wiper position of the MAX5450–MAX5455. With CS low and U/D high, a high-to-low (falling edge) transition on INC ,increments the internal counter, which increases the resistance between W and L. When both CS and U/D are low, a high-to-low INC transition decrements the internal counter, decreasing the resistance between W and L (Figure 1). The wiper performs a make-before-break transition ensuring that there is never an open circuit during a transition from one resistor tap to anoth-er. When the wiper is at either end (max/min) of the resistor array, additional transitions in the direction of the endpoint will not change the counter value (the counter will not wrap around).The MAX5450/MAX5452/MAX5454 are similar to the MAX5451/MAX5453/MAX5455 except for internal con-nections. The MAX5450/MAX5452/MAX5454 internally connect INC1to INC2, U/D1to U/D2, W1 to H1, and W2 to H2 (Figures 3 and 4). The internal connections configure the MAX5450/MAX5452/MAX5454 to be vari-able resistors.Applications InformationThe MAX5450–MAX5455 are ideal for adjustable volt-age or adjustable gain circuits where accurate adjustable resistances are required.Adjustable Current to Voltage ConverterFigure 5shows the MAX5450/MAX5452/MAX5454 with a MAX4250 low-noise op amp to fine-tune a current to voltage converter. The physical sizes of both devices minimize circuit space.Adjustable Gain AmplifierFigures 6a and 6b shows the MAX5450–MAX5455 digi-tally adjusting the gain of the MAX4493 general-pur-pose, dual supply op amp. Figure 6a shows the MAX5450/MAX5452/MAX5454 variable resistor in series with a resistor to ground to form the adjustable gain control. Figure 6b shows the MAX5451/MAX5453/MAX5455 as a 3-terminal potentiometer. In these appli-cations the low 5ppm/°C ratiometric tempco allows for a very stable adjustable gain over temperature.Adjustable Linear RegulatorIn Figure 7, the MAX5450/MAX5452/MAX5454 is shown digitally adjusting the output voltage of the MAX8866dual linear regulator. In this circuit, the MAX5450/MAX5452/MAX5454 is connected in series with a resis-tor to ground to form the adjustable feedback stage.The 8-bit MAX5450/MAX5452/MAX5454 allows precise tuning of the output voltage.Dual, 256-Tap, Up/Down Interface,Digital Potentiometers 8_______________________________________________________________________________________Figure 1.
