Data Sheet 26301.100†The A3933SEQ is a three-phase MOSFET controller for use with bipolar brushless dc motors. It drives all n-channel external power FETs, allowing system cost savings and minimizing r (DS)on power loss.The high-side drive block is implemented with bootstrap capacitors at each output to provide the floating positive supply for the gate drive.The high-side circuitry also employs a unique “intelligent” FETmonitoring circuit that ensures the gate voltages are at the proper levels before turn-on and during the ON cycle. This device is targeted for applications with motor supplies from 12 V to 28 V.Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. The peak load-current limit is set by the user’s selection of an input reference voltage and external sensing resistor. The fixed off-time pulse duration is set by a user-selected external RC timing network.A power-loss braking circuit brakes the motor on an under-voltage condition. The device is configured to either coast or dynamically brake the motor when this occurs.The A3933SEQ is supplied in a 32-lead rectangular (9 x 7) plasticchip carrier (quad pack) for minimum-area, surface-mount applica-tions.3933FEATURES AND BENEFITSI Drives External N-Channel FETs I Intelligent High-Side Gate DriveI Selectable Coast or Dynamic Brake on Power Down I Adjustable Dead Time for Cross-Conduction Protection I Selectable Fast or Slow Current-Decay Modes I Internal PWM Peak Current Control I Reset/Coast InputI 120° Hall Commutation with Internal Pullup I Internal 5-V RegulatorI Low-Side Synchronous Rectification I Direction ControlI PWM Speed-Control Input I Fault-Diagnostic Output IUnder-Voltage ProtectionTHREE-PHASE POWER MOSFET CONTROLLER115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-********THREE-PHASE POWER MOSFET CONTROLLERCopyright © 1999, Allegro MicroSystems, Inc.Functional Block DiagramRECOMMENDED OPERATING CONDITIONSSupply Voltage, V BB ...................................... 15 V to 28 Vor, if V BB = V CCOUT ................................... 12 V ±10%Logic Input Voltage Range, V IN .............. -0.3 V to +4.8 V Sense Voltage Range, V SENSE ........................ -1 V to +1 V RC Resistance.......................................... 10 k Ω to 100 k ΩPWM Frequency, f PWM ....................... 20 kHz to 100 kHzLOW-SIDE Dwg.

A logic HIGH will disable the device and force all gate drivers to 0 V, coasting the motor. A logic LOW allows the gate drive to follow commutation logic.This input overrides BRAKE.GLA/GLB/GLC — Low-side, gate-drive outputs for external NMOS drivers. External series-gate resistors (as close aspossible to the NMOS gate) can be used to control the slew rate seen at the power-driver gate, thereby controlling the di/dt and dv/dt of the SA/SB/SC outputs. Each output is designed and specified to drive a 1000 pF load with a rise time of 50 ns.SA/SB/SC — Directly connected to the motor, these terminals sense the voltages switched across the load. These terminals are also connected to the negative side of the bootstrap capaci-tors and are the negative supply connections for the floating high-side drive.GHA/GHB/GHC — High-side, gate-drive outputs for external NMOS drivers. External series-gate resistors (as close aspossible to the NMOS gate) can be used to control the slew rate seen at the power-driver gate, thereby controlling the di/dt and dv/dt of the SA/SB/SC outputs.

The bootstrap capacitor is charged to approximately V CCOUT when theassociated output SA/SB/SC terminal is low. When the output swings high, the voltage on this terminal rises with the output to provide the boosted gate voltage needed for n-channel power FETs.Terminal Descriptionscontinued next page115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-50003933THREE-PHASE POWER MOSFET CONTROLLERFAULT — Open-drain output to indicate fault condition; will go active high for any of the following:1 – invalid HALL input code,2 – high-side, gate-source voltage less than 7 V,3 – bootstrap capacitor not sufficiently charged, or4 – under-voltage condition detected at V CCOUT .The fault state for gate-source and bootstrap monitors are cleared at each commutation. If the motor has stalled, then the fault can only be cleared by toggling the RESET terminal or power-up sequence.MODE — A logic input to set current-decay method, internally pulled up to V LCAP (+5 V). When in slow-decay mode (logic HIGH), only the high-side FET is switched open during a PWM OFF cycle. The fast-decay mode (logic LOW) switches both the source and sink FETs.H1/H2/H3 — Hall-sensor inputs; internally pulled up to V LCAP (+5 V). Configured for 120° electrical spacing.DIR — A logic input to reverse rotation, see commutation logic table. Internally pulled up to V LCAP (+5 V).BRAKE — A logic input to short out the motor windings for a braking function. A logic HIGH will turn ON the low-side FETs, turn OFF the high-side FETs. Internally pulled up to V LCAP (+5 V). The braking torque applied will depend on the speed.BRKCAP — Connection for reservoir capacitor. This terminal is used to provide a positive power supply for the sink-drive outputs for a power-down condition. This will allow predict-able braking, if desired. A blocking diode to V CCOUT is re-quired. A 4.7 µF capacitor will provide 6.5 V gate drive for 300 ms. If a power-down braking option is not needed(BRKSEL = LOW) then this terminal should be tied to V CCOUT .BRKSEL — A logic input to enable/disable braking on power-down condition. Internally pulled up to V LCAP (+5 V). If held low, the motor will coast on a power-down condition.PWM — Speed control input, internally pulled up to V LCAP(+5 V). A logic LOW turns OFF all drivers, a logic HIGH will turn ON selected drivers as determined by H1/H2/H3 input logic. Holding the terminal high allows speed/torque control solely by the current-limit circuit via REF analog voltage command.RC — An analog input used to set the fixed off time with an external resistor (R T ) and capacitor (C T ). The t blank time is controlled by the value of the external capacitor (see Applica-tions Information). As a rule, the fixed off time should not be less than 10 µs. The resistor should be in the range of 10 k Ω to 100 k Ω.SENSE — An analog input to the current-limit comparator.A voltage representing load current appears on this terminal during ON time, when it reaches REF voltage, the comparator trips and load current decays for the fixed off-time interval.Voltage transients seen at this terminal when the drivers turn ON are ignored for time t blank .REF — An analog input to the current-limit comparator.Voltage applied here sets the peak load current.I peak = V REF /R S .V CCOUT — A regulated 12 V output; supply for low-side gate drive and bootstrap capacitor charge circuits. It is good practice to connect a decoupling capacitor from this terminal to AGND,as close to the device terminals as possible. The terminal should be shorted to V BB for 12 V applications.V BB — The A3933 supply voltage. It is good practice toconnect a decoupling capacitor from this terminal to AGND, as close to the device terminals as possible. This terminal should be shorted to V CCOUT for 12 V applications.LCAP — Connection for decoupling capacitor for the internal 5 V reference. This terminal can source no more than 2 mA.DEAD — An analog input. A resistor between DEAD and LCAP is selected to adjust turn-off to turn-on time. This delay is needed to prevent shoot-through in the external power FETs.The allowable resistor range is 20 k Ω to 430 k Ω, whichconverts to deadtime of 210 ns to 2.1 µs, using the following equation:t DEAD = (6.75 x 10-12 x R DEAD ) + (75 x 10-9).AGND — The low-level (analog) reference point for the A3933.PGND — The reference point for all low-side gate drivers.Terminal Descriptions (cont’d)3933 THREE-PHASE POWER MOSFET CONTROLLER Commutation Truth TableLogic Inputs Driver OutputsH1H2H3DIR GLA GLB GLC GHA GHB GHC SA SB SCH L H H L L H H L L H Z L H L L H L L H L H L Z H L H H L H H L L L H L L H Z L H L H H L L L L H L Z H L H H H L H L L L H Z L H L L H H L H L H L L H L Z H L H L H L L L L H L Z H H L L L L H L L L H Z L H H H L L L H L H L L H L Z L H L L L L H H L L H Z L L H H L L L H L H L Z H L L L H L H L L L H L L H ZInput LogicMODE PWM RESET Mode OperationL L L Fast decay PWM chop mode, current decayL H L Fast decay Peak current limit, selected drivers ONH L L Slow decay PWM chop mode. current decayH H L Slow decay Peak current limit, selected drivers ONX X H Coast All gate drive outputs OFF, clear fault logicBrake ControlBRAKE BRKSEL Normal Operation Under Voltage or Power Loss ConditionL L Normal run mode Coast, all gate drive outputs OFFL H Normal run mode Dynamic brake, all sink gate drives ONH L Dynamic brake, all sink gate drives ON Coast, all gate drive outputs OFFH H Dynamic brake, all sink gate drives ON Dynamic brake, all sink gate drives ONL = Low Level, H = High Level, X = Don’t Care, Z = High Impedance115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-50003933THREE-PHASE POWER MOSFET CONTROLLERApplications Informationbootstrap capacitor. When the bootstrap capacitor has been properly charged, the high side is turned back ON. The circuit will allow three faults of this type within one commutation cycle before signaling a fault and coast the motor (all gate outputs go low).2)Bootstrap Monitor. The bootstrap capacitor is charged whenever a sink-side MOSFET is ON, Sx output goes low, and the load current recirculates. This happens constantly during normal operation. A 60 µs timer is started at the beginning of this cycle and the capacitor is charged with typically 100 mA.The bootstrap capacitor voltage is clamped at approximately 87% of V CCOUT . If the capacitor is not charged to the clamp voltage in 60 µs, a fault is signaled and the motor will coast.3)Undervoltage. The internal V CCOUT regulator supplies the low-side gate driver and the bootstrap charge current. It is critical to ensure that the voltages are at a proper level before enabling any of the outputs. The undervoltage circuit is active during power up and will force a motor coast condition until V CCOUT is greater than approximately 10 V.4)Hall Invalid. Illegal codes for the HALL inputs (000 or 111) will force a fault and coast the motor.Faults are cleared at the beginning of each commutation. If a stalled motor results from a fault, the fault can only be cleared by toggling the RESET terminal or by a power-up sequence.Current Control. Internal fixed off-time PWM circuitry is implemented to limit load current to a desired value. The external sense resistor combined with the applied analog voltage to REF terminal will set the peak current level approximatelyI TRIP ≈ V REF /R S .After the peak level is reached, the sense comparator trips and the load current will decay for a fixed off time.An external resistor (R T ) and capacitor (C T ) are used to set the fixed off-time period (t off = R T x C T ). The t off should be in the range of 10 µs to 50 µs. Longer values for t off can result in audible noise problems.Torque control can be implemented by varying the REF input voltage as long as the PWM input stays high. If direct control of the torque/current is desired by PWM input, a voltage can be applied to the REF input to set an absolute maximum current limit.Bootstrap Capacitor Selection. The high-side bootstrap circuit operates on a charge-transfer principle. The gate charge (Q g ) specification of the external power MOSFET must betaken into consideration. The bootstrap capacitor must be large enough to turn on the MOSFET without losing significant gate voltage. If the bootstrap capacitor is too large, it would take too long to charge up during the off portion of the PWM cycle. The capacitor value must be selected with both of these constraints in mind.1)Minimum bootstrap capacitor value to transfer charge. The charge on the bootstrap capacitor should be 20x greater than the gate charge (Q g ) of the power MOSFET.Example: For Q g = 0.025 µC, selectC boot = 20 x Q g /10.5 V = 0.047 µF.Check for maximum V g drop at turn on: dq = C boot x dV g , where Q g = dq.dV g = dq/C boot = 0.025 µC/0.047 µF = 532 mV.2)Calculate minimum PWM “OFF” cycle with C boot = 0.047 µF.dt = r o x C boot x ln(0.036/[Q g /C boot + 0.036])where r o = 20 ohms, the equivalent internal series resistance of the bootstrap capacitor monitor circuit.The sink-side MOSFET will be held OFF for this minimum time such that the bootstrap capacitor can be recharged independently of the PWM input frequency.The above equation is valid for PWM cycles after the bootstrap capacitor has been charged once. For the first cycle after a motor phase commutates from Hi-Z to GHx ON, or during the first charging cycle at power-up, the circuit will ignore PWM signals until it has been charged.The time required to charge up at power up and at commutation change is approximately:t = C boot x 7 V/0.1 AProtection Circuitry. The A3933 will protect the external MOSFETs by shutting down the gate drive if any of the following conditions are detected:1)Gate Source Monitor (high side only). The voltage on the GHx terminals must stay 7 V higher than the source. If this voltage droops below the threshold, the high side turns OFF,and the low-side gate will turn ON in an attempt to recharge the3933 THREE-PHASE POWER MOSFET CONTROLLER Applications Information (cont’d)PWM Blank. The capacitor (C T) also serves as the means to set the blank time duration. After the off time expires, the selected gates are turned back ON. At this time, large current transients can occur during the reverse recovery time (t rr) of the intrinsic body diodes of the external MOSFETs. To prevent the current-sense comparator from thinking the current spikes are a real overcurrent event, the comparator is blanked:t blank = 1.9 x C T/(1 mA-2/R T)The user must ensure that C T is large enough to cover the current-spike duration.Load Current Recirculation. If MODE has been set for slow decay, the high-side (source) driver will turn OFF forcing the current to recirculate through the pair of sink MOSFETs. If MODE has been selected for fast decay, both the selected high-and low-side gates are turned OFF, which will force the current to recirculate through one sink MOSFET and the high-side clamp diode. Synchronous rectification (only on the low side) allows current to flow through the MOSFET, rather than the clamp diode, during the decay time. This will minimize power loss during the off period. It is important to take into account that, when switching, the intrinsic diodes will conduct during the adjustable deadtime.Braking. The A3933 will dynamically brake by forcing all sink-side MOSFETs ON. This will effectively short out the BEMF. During braking, the load current can be approximated by:I BRAKE = V BEMF/R LPower Loss Brake. The BRKCAP and BRKSEL terminals provide a power-down braking option. By applying a logic level to input BRKSEL, the system can control if the motor is dynamically braked or is allowed to coast during an undervoltage event. The reservoir capacitor on the BRKCAP terminal provides the power to hold the sink-side gates ON after supply voltage is lost. A logic high on BRKSEL will brake the motor, a logic low and it will coast.Layout. Careful consideration must be given to PCB layout when designing high-frequency, fast-switching, high-current circuits.1)The analog ground (AGND), the power ground (PGND), and the high-current return of the external MOSFETs (the negative side of the sense resistor) should return separately to the negative side of the motor supply filtering capacitor. This will minimize the effect of switching noise on the device logic and analog reference.2)Minimize stray inductances by using short, wide copper runs at the drain and source terminals of all power MOSFETs. This includes motor lead connections, the input power buss, and the common source of the low-side power MOSFETs. This will minimize voltages induced by fast switching of large load currents.3)Kelvin connect the SENSE terminal PC trace to the positive side of the sense resistor.115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-50003933THREE-PHASE POWER MOSFET CONTROLLERDimensions in Inches(controlling dimensions)Dwg.

®X9315Low Noise, Low Power, 32 TapsDigitally Controlled Potentiometer (XDCP™)The Intersil X9315 is a digitally controlled potentiometer (XDCP). The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a 3-wire interface.The potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in nonvolatilememory and then be recalled upon a subsequent power-up operation.The device can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including:•Control•Parameter Adjustments •Signal ProcessingFeatures•Solid-state potentiometer •3-wire serial interface•32 wiper tap points-Wiper position stored in nonvolatile memory and recalled on power-up •31 resistive elements-Temperature compensated-End to end resistance range ± 20% -Terminal voltage, 0 to V CC •Low power CMOS -V CC = 2.7V or 5V-Active current, 50/400µA max.-Standby current, 1µA max.•High reliability-Endurance, 100,000 data changes per bit -Register data retention, 100 years •R TOTAL values = 10k Ω, 50k Ω, 100k Ω•Packages-8 Ld SOIC, MSOP and PDIP•Pb-free plus anneal available (RoHS compliant)Block DiagramH /V HL /V L W /V WUp/Down(U/D)Increment(INC)(CS)V (Supply Voltage)SS R H /V HR W /V R L /V LGeneralDetailedOrdering InformationPART NUMBER PART MARKING V CC LIMITS(V)R TOTAL(kΩ)TEMP RANGE(°C)PACKAGEX9315WM*AAW 5 ±10% 100 to 708 Ld MSOPX9315WMZ* (Note)DDT0 to 708 Ld MSOP (Pb-free) X9315WMI*AAX-40 to 858 Ld MSOPX9315WMIZ* (Note)AKW-40 to 858 Ld MSOP (Pb-free) X9315WP X9315WP0 to 708 Ld PDIPX9315WPI X9315WP I-40 to 858 Ld PDIPX9315WS*X9315W0 to 708 Ld SOICX9315WSZ* (Note)X9315W Z0 to 708 Ld SOIC (Pb-free) X9315WSI*X9315W I-40 to 858 Ld SOICX9315WSIZ* (Note)X9315W Z I-40 to 858 Ld SOIC (Pb-free) X9315UM*500 to 708 Ld MSOPX9315UMZ* (Note)DDS0 to 708 Ld MSOP (Pb-free) X9315UMI*AEB-40 to 858 Ld MSOPX9315UMIZ* (Note)DDR-40 to 858 Ld MSOP (Pb-free) X9315UP X9315UP0 to 708 Ld PDIPX9315UPI X9315UP I-40 to 858 Ld PDIPX9315US*X9315U0 to 708 Ld SOICX9315USZ* (Note)X9315U Z0 to 708 Ld SOIC (Pb-free) X9315USI*X9315U I-40 to 858 Ld SOICX9315USIZ* (Note)X9315U Z I-40 to 858 Ld SOIC (Pb-free) X9315TM*AEJ1000 to 708 Ld MSOPX9315TMZ* (Note)DDN0 to 708 Ld MSOP (Pb-free) X9315TMI*ADZ-40 to 858 Ld MSOPX9315TMIZ* (Note)DDL-40 to 858 Ld MSOP (Pb-free) X9315TP X9315TP0 to 708 Ld PDIPX9315TPI X9315TP I-40 to 858 Ld PDIPX9315TS*X9315T0 to 708 Ld SOICX9315TSZ* (Note)X9315T Z0 to 708 Ld SOIC (Pb-free) X9315TSI*X9315T I-40 to 858 Ld SOICX9315TSIZ* (Note)X9315T Z I-40 to 858 Ld SOIC (Pb-free)X9315TP-2.7X9315TP F 2.7-5.5100 to 708 Ld PDIP X9315TPI-2.7X9315TP G -40 to 858 Ld PDIP X9315WM-2.7*AAU 0 to 708 Ld MSOPX9315WMZ-2.7* (Note)AOI 0 to 708 Ld MSOP (Pb-free)X9315WMI-2.7*AAV-40 to 858 Ld MSOPX9315WMIZ-2.7* (Note)-40 to 858 Ld MSOP (Pb-free)X9315WP-2.7X9315WP F 0 to 708 Ld PDIP X9315WPI-2.7X9315WP G -40 to 858 Ld PDIP X9315WS-2.7*X9315W F 0 to 708 Ld SOICX9315WSZ-2.7* (Note)X9315W Z F 0 to 708 Ld SOIC (Pb-free)X9315WSI-2.7*X9315W G -40 to 858 Ld SOICX9315WSIZ-2.7* (Note)X9315W Z G -40 to 858 Ld SOIC (Pb-free)X9315UM-2.7*AEK 500 to 708 Ld MSOPX9315UMZ-2.7* (Note)AKU 0 to 708 Ld MSOP (Pb-free)X9315UMI-2.7*AEA -40 to 858 Ld MSOPX9315UMIZ-2.7* (Note)AJG-40 to 858 Ld MSOP (Pb-free)X9315UP-2.70 to 708 Ld PDIP X9315UPI-2.7-40 to 858 Ld PDIP X9315US-2.7*X9315U F 0 to 708 Ld SOICX9315USZ-2.7* (Note)X9315U Z F 0 to 708 Ld SOIC (Pb-free)X9315USI-2.7*X9315U G -40 to 858 Ld SOICX9315USIZ-2.7* (Note)X9315U Z G -40 to 858 Ld SOIC (Pb-free)X9315TM-2.7*AEI 1000 to 708 Ld MSOPX9315TMZ-2.7* (Note)DDP 0 to 708 Ld MSOP (Pb-free)X9315TMI-2.7*ADY -40 to 858 Ld MSOPX9315TMIZ-2.7* (Note)DDM -40 to 858 Ld MSOP (Pb-free)X9315TS-2.7*X9315T F 0 to 708 Ld SOICX9315TSZ-2.7* (Note)X9315T Z F 0 to 708 Ld SOIC (Pb-free)X9315TSI-2.7*X9315T G -40 to 858 Ld SOICX9315TSIZ-2.7* (Note)X9315T Z G-40 to 858 Ld SOIC (Pb-free)NOTE:Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations.

The minimum voltage is V SS and the maximum is V CC . The terminology of R L /V L and R H /V H references the relative position of the terminal in relation to wiper movement direction selected by the U/D input, and not the voltage potential on the terminal.R W /V WR W /V w is the wiper terminal and is equivalent to the movable terminal of a mechanical potentiometer. The position of the wiper within the array is determined by the control inputs. The wiper terminal series resistance is typically 200Ω at V CC = 5V.Up/Down (U/D)The U/D input controls the direction of the wiper movement and whether the counter is incremented or decremented.Increment (INC)The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or decrement the counter in the direction indicated by the logic level on the U/D input.Chip Select (CS)The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete the X9315 will be placed in the low power standby mode until the device is selected once again.Pin ConfigurationPrinciples of OperationThere are three sections of the X9315: the input control, counter and decode section; the nonvolatile memory; and the resistor array. The input control section operates just like an up/down counter. The output of this counter is decoded to turn on a single electronic switch connecting a point on the resistor array to the wiper output. Under the proper conditions the contents of the counter can be stored innonvolatile memory and retained for future use. The resistor array is comprised of 31 individual resistors connected in series. At either end of the array and between each resistor is an electronic switch that transfers the connection at that point to the wiper.The wiper, when at either fixed terminal, acts like itsmechanical equivalent and does not move beyond the last position. That is, the counter does not wrap around when clocked to either extreme.The electronic switches on the device operate in a “make before break” mode when the wiper changes tap positions. If the wiper is moved several positions, multiple taps are connected to the wiper for t IW (INC to V W change). The R TOTAL value for the device can temporarily be reduced by a significant amount if the wiper is moved several positions.When the device is powered-down, the last wiper position stored will be maintained in the nonvolatile memory. When power is restored, the contents of the memory are recalled and the wiper is set to the value last stored.Instructions and ProgrammingThe INC, U/D and CS inputs control the movement of the wiper along the resistor array. With CS set LOW the device is selected and enabled to respond to the U/D and INC inputs. HIGH to LOW transitions on INC will increment or decrement (depending on the state of the U/D input) a five bit counter. The output of this counter is decoded to select one of thirty two wiper positions along the resistive array.The value of the counter is stored in nonvolatile memory whenever CS transitions HIGH while the INC input is also HIGH.The system may select the X9315, move the wiper and deselect the device without having to store the latest wiper position in nonvolatile memory. After the wiper movement is performed as described above and once the new position is reached, the system must keep INC LOW while taking CS HIGH. The new wiper position will be maintained untilPin NamesSYMBOL DESCRIPTION R H /V H High terminal R W /V W Wiper terminal R L /V L Low terminal V SS Ground V CC Supply voltage U/DUp/Down control inputV CC CS INC U/D R H /V H V SS12348765X9315DIP/SOIC/MSOPR L /V L R W /V WINC Increment control input CSChip Select control inputPin NamesSYMBOL DESCRIPTIONchanged by the system or until a power-up/down cycle recalled the previously stored data.This procedure allows the system to always power-up to a preset value stored in nonvolatile memory; then during system operation minor adjustments could be made. The adjustments might be based on user preference, system parameter changes due to temperature drift, etc...The state of U/D may be changed while CS remains LOW. This allows the host system to enable the device and then move the wiper up and down until the proper trim is attained.Symbol TableMode SelectionCS INCU/D MODEL H Wiper Up LL Wiper Down HX Store Wiper Position HX X Standby CurrentL XNo Store, Return to StandbyWAVEFORMINPUTS OUTPUTS Must be steady Will be steady May change from Lo w to High Will change from Lo w to High May change from High to Low Will change from High to Low Don’t Care:Changes Allowed Changing:State Not Known N/ACenter Line is High ImpedanceNotes:(1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (V w(n)(actual) - V w(n)(expected)) = ±1 MlMaximum.(2) Relative linearity is a measure of the error in step size between taps = R W(n+1) - [R w(n) + Ml] = ±0.2 Ml.(3) 1 Ml = Minimum Increment = R TOT /31.(4) Typical values are for T A = 25°C and nominal supply voltage.(5) This parameter is periodically sampled and not 100% testedAbsolute Maximum RatingsRecommended Operating ConditionsTemperature under bias. . . . . . . . . . . . . . . . . . . . . .-65°C to +135°C Storage temperature . . . . . . . . . . . . . . . . . . . . . . . .-65°C to +150°C Voltage on CS, INC, U/D, V H , V L andV CC with respect to V SS . . . . . . . . . . . . . . . . . . . . . . . -1V to +7V ∆V = |V H –V L |. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .5V Lead temperature (soldering 10 seconds). . . . . . . . . . . . . . . .300°C I W (10 seconds). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .±7.5mATemperature (Commercial) . . . . . . . . . . . . . . . . . . . . . 0°C to +70°C Temperature (Industrial). . . . . . . . . . . . . . . . . . . . . . .-40°C to +85°C Supply Voltage (V CC ) (Note 4) LimitsX9315. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5V ± 10%X9315-2.7. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2.7V to 5.5VCAUTION: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in nonvolatile memory and then be recalled upon a subsequent power-up operation.
