These pins are internally pulledup to 5.0 V providing logic ones if left open. V ID4 selects theDAC range. When V ID4 is High (logic one), the DAC rangeis 2.10 V to 3.50 V with 100 mV increments. When V ID4 isLow (logic zero), the DAC range is 1.30 V to 2.05 V with50 mV increments. V ID0− V ID4 select the desired DAC out-put voltage. Leaving all 5 DAC input pins open results in aDAC output voltage of 1.2440 V, allowing for adjustableoutput voltage, using a traditional resistor divider.5SS Soft Start Pin. A capacitor from this pin to LGnd in conjunc-tion with internal 60 μA current source provides Soft Startfunction for the controller. This pin disables fault detect func-tion during Soft Start. When a fault is detected, the Soft Startcapacitor is slowly discharged by internal 2.0 μA currentsource setting the time out before trying to restart the IC.Charge/discharge current ratio of 30 sets the duty cycle forthe IC when the regulator output is shorted.7C OFF A capacitor from this pin to ground sets the time duration forthe on board one shot, which is used for the constant off timearchitecture.8V FFB Fast feedback connection to the PWM comparator.

All control circuits are referenced tothis pin.15COMP Error amplifier compensation pin. A capacitor to groundshould be provided externally to compensate the amplifier.16V FB Error amplifier DC feedback input. This is the master voltagefeedback which sets the output voltage. This pin can be con-nected directly to the output or a remote sense trace.VVVVVVVV2Figure 3. V2 Control DiagramThe V2 control method is illustrated in Figure 3. The output voltage is used to generate both the error signal and the ramp signal. Since the ramp signal is simply the output voltage, it is affected by any change in the output regardless of the origin of that change. The ramp signal also contains the DC portion of the output voltage, which allows the control circuit to drive the main switch to 0% or 100% duty cycle as required.A change in line voltage changes the current ramp in the inductor, affecting the ramp signal, which causes the V2 control scheme to compensate the duty cycle. Since the change in inductor current modifies the ramp signal, as in current mode control, the V2 control scheme has the same advantages in line transient response.A change in load current will have an affect on the output voltage, altering the ramp signal. A load step immediately changes the state of the comparator output, which controls the main switch. Load transient response is determined only by the comparator response time and the transition speed of the main switch. The reaction time to an output load step has no relation to the crossover frequency of the error signal loop, as in traditional control methods.The error signal loop can have a low crossover frequency, since transient response is handled by the ramp signal loop. The main purpose of this ‘slow’ feedback loop is to provide DC accuracy. Noise immunity is significantly improved, since the error amplifier bandwidth can be rolled off at a low frequency. Enhanced noise immunity improves remote sensing of the output voltage, since the noise associated with long feedback traces can be effectively filtered.Line and load regulation are drastically improved because there are two independent voltage loops. A voltage mode controller relies on a change in the error signal to compensate for a deviation in either line or load voltage. This change in the error signal causes the output voltage to change corresponding to the gain of the error amplifier, which is normally specified as line and load regulation. A current mode controller maintains fixed error signal under deviation in the line voltage, since the slope of the ramp signal changes, but still relies on a change in the error signal for a deviation in load. The V2 method of control maintains a fixed error signal for both line and load variation, since the ramp signal is affected by both line and load.Constant Off TimeTo maximize transient response, the CS5160 uses a constant off time method to control the rate of output pulses. During normal operation, the off time of the high side switch is terminated after a fixed period, set by the C OFF capacitor. To maintain regulation, the V2 control loop varies switch on time. The PWM comparator monitors the output voltage ramp, and terminates the switch on time.Constant off time provides a number of advantages. Switch duty cycle can be adjusted from 0 to 100% on a pulse by pulse basis when responding to transient conditions. Both 0% and 100% duty cycle operation can be maintained for extended periods of time in response to load or line transients. PWM slope compensation to avoid sub−harmonic oscillations at high duty cycles is avoided. Switch on time is limited by an internal 30 μs timer, minimizing stress to the power components. Programmable OutputThe CS5160 is designed to provide two methods for programming the output voltage of the power supply. A five bit on board digital to analog converter (DAC) is used to program the output voltage within two different ranges. The first range is 2.10 V to 3.50 V in 100 mV steps, the second is 1.30 V to 2.05 V in 50 mV steps, depending on the digital input code. If all five bits are left open, the CS5160 enters adjust mode. In adjust mode, the designer can choose any output voltage by using resistor divider feedback to the V FB and V FFB pins, as in traditional controllers.Start UpUntil the voltage on the V CC1 supply pin exceeds the 9.05 V monitor threshold, the Soft Start and gate pins are held low. The FAULT latch is reset (no Fault condition). The output of the error amplifier (COMP) is pulled up to 1.0 V by the comparator clamp. When the V CC1 pin exceeds the monitor threshold, the GA TE(H) output is activated, and the Soft Start capacitor begins charging. The GATE(H) output will remain on, enabling the NFET switch, until terminated by either the PWM comparator, or the maximum on time timer.If the maximum on time is exceeded before the regulator output voltage achieves the 1.0 V level, the pulse is terminated. The GA TE(H) pin drives low, and the GATE(L) pin drives high for the duration of the extended off time. This time is set by the time out timer and is approximately equal to the maximum on time, resulting in a 50% duty cycle. The GATE(L) pin will then drive low, the GATE(H) pin will drive high, and the cycle repeats.When regulator output voltage achieves the 1.0 V level present at the COMP pin, regulation has been achieved and normal off time will ensue. The PWM comparator terminates the switch on time, with off time set by the C OFF capacitor. The V2 control loop will adjust switch duty cycle as required to ensure the regulator output voltage tracks the output of the error amplifier.The Soft Start and COMP capacitors will charge to their final levels, providing a controlled turn on of the regulator output. Regulator turn on time is determined by the COMP capacitor charging to its final value. Its voltage is limited bythe Soft Start COMP clamp and the voltage on the Soft Start pin (see Figures 4 and 5).Figure 4. CS5160 Startup in Response to Increasing 12 V and 5.0 V Input Voltages.

Switch on time is adjusted by the V 2 control loop to maintain regulation. This results in changes in regulator switching frequency, duty cycle, and output ripple in response to changes in load and line. Output voltage ripple will be determined by inductor ripple current working into the ESR of the output capacitors (see Figures 7 and 8).Figure 7.

This causes the top MOSFET to shut off,disconnecting the regulator from it’s input voltage. The Soft Start capacitor is then slowly discharged by a 2.0 μA current source until it reaches it’s lower 0.7 V threshold. The regulator will then attempt to restart normally, operating in it’s extended off time mode with a 50% duty cycle, while the Soft Start capacitor is charged with a 60 μA charge current.If the short circuit condition persists, the regulator output will not achieve the 1.0 V low V FFB comparator threshold before the Soft Start capacitor is charged to it’s upper 2.5 V threshold. If this happens the cycle will repeat itself until the short is removed. The Soft Start charge/discharge current ratio sets the duty cycle for the pulses (2.0 μA/60 μA = 3.3%), while actual duty cycle is half that due to the extended off time mode (1.65%).This protection feature results in less stress to the regulator components, input power supply, and PC board traces than occurs with constant current limit protection (see Figures 12 and 13).If the short circuit condition is removed, output voltage will rise above the 1.0 V level, preventing the FAULT latch from being set, allowing normal operation to resume.Figure 12.

The control loop responds to an overvoltage condition within 100 ns, causing the top MOSFET to shut off, disconnecting the regulator from it’s input voltage. The bottom MOSFET is then activated,resulting in a “crowbar” action to clamp the output voltage and prevent damage to the load (see Figures 14 and 15). The regulator will remain in this state until the overvoltage condition ceases or the input voltage is pulled low. The bottom FET and board trace must be properly designed to implement the OVP function.Figure 14.

The scheme that prevents that switching noise prematurely triggers the PWM circuit consists of adding a positive voltage slope to the output of the Error Amplifier (COMP pin) during an off−time cycle.The circuit that implements this function is shown in Figure 19.following gate drive is provided;V GATE(H)+12V*5.0V+7.0V,V GATE(L)+12V (see Figure 20.)Figure 20.

The power dissipation in the synchronous MOSFET due to body diode conduction can be estimated by the following equation:Power +V BD I LOAD conduction time switching frequencyWhere VFigure 8;Power +load.Thermal A heatsink may be added to TO −220 components to reduce their thermal impedance. A number of PC board layout techniques such as thermal vias and additional copper foil area can be used to improve the power handling capability of surface mount components.EMI ManagementAs a consequence of large currents being turned on and off at high frequency, switching regulators generate noise as a consequence of their normal operation. When designing for compliance with EMI/EMC regulations, additional components may be added to reduce noise emissions.

For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI and reduce 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 to transmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, while the MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features♦For Fault-Tolerant ApplicationsMAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 TransceiverMAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers♦For Space-Constrained ApplicationsMAX3460–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-422,True Fail-Safe ReceiversMAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-855/RS-422 Transmitters ♦For Multiple Transceiver ApplicationsMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Fail-Safe ApplicationsMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceivers♦For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 TransceiversMAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________Selection Table19-0122; Rev 8; 10/03Ordering Information appears at end of data sheet.M A X 481/M A X 483/M A X 485/M A X 487–M A X 491/M A X 1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSSupply Voltage (V CC ).............................................................12V Control Input Voltage (RE , DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (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)....727mW 14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW 8-Pin µMAX (derate 4.1mW/°C above +70°C)..............830mW 8-Pin CERDIP (derate 8.00mW/°C above +70°C).........640mW 14-Pin CERDIP (derate 9.09mW/°C above +70°C).......727mW Operating Temperature RangesMAX4_ _C_ _/MAX1487C_ A...............................0°C to +70°C MAX4__E_ _/MAX1487E_ A.............................-40°C to +85°C MAX4__MJ_/MAX1487MJA...........................-55°C to +125°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.)

The MAX481, MAX485, MAX490,MAX491, and MAX1487 can transmit and receive at data rates up to 2.5Mbps, while the MAX483, MAX487,MAX488, and MAX489 are specified for data rates up to 250kbps. The MAX488–MAX491 are full-duplex trans-ceivers while the MAX481, MAX483, MAX485, MAX487,and MAX1487 are half-duplex. In addition, Driver Enable (DE) and Receiver Enable (RE) pins are included on the MAX481, MAX483, MAX485, MAX487, MAX489,MAX491, and MAX1487. When disabled, the driver and receiver outputs are high impedance.MAX487/MAX1487:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487 and MAX1487 allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 trans-ceivers maximum). Any combination of MAX487/MAX1487 and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus.

Figure 12 shows the dri-ver output waveform and its Fourier analysis of a 150kHz signal transmitted by a MAX481, MAX485,MAX490, MAX491, or MAX1487. High-frequency har-monics with large amplitudes are evident. Figure 13shows the same information displayed for a MAX483,MAX487, MAX488, or MAX489 transmitting under the same conditions. Figure 13’s high-frequency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers_______________________________________________________________________________________9_________________________________________________________________Test CircuitsFigure 4.

Receiver Enable and Disable Times (except MAX488and MAX490)Table 1. TransmittingTable 2. ReceivingLow-Power Shutdown Mode (MAX481/MAX483/MAX487)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 0.1µA 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 MAX481, MAX483, and MAX487, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485/MAX488–MAX491and MAX1487 can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).It 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 –R —E –,DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output ProtectionExcessive 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 cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a ther-mal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively.Propagation DelayMany digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 15–18 using Figure 14’s test circuit.The difference in receiver delay times, | t PLH - t PHL |, is typically under 13ns for the MAX481, MAX485,MAX490, MAX491, and MAX1487 and is typically less than 100ns for the MAX483 and MAX487–MAX489.The driver skew times are typically 5ns (10ns max) for the MAX481, MAX485, MAX490, MAX491, and MAX1487, and are typically 100ns (800ns max) for the MAX483 and MAX487–MAX489.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________1110dB/div0Hz5MHz500kHz/div10dB/div0Hz5MHz500kHz/divFigure 12.

These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 23.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.

(1)Pin descriptionPin function6.Driver installation instructionsThe pins with white block diagram on the driver are enabled (EN) pins as shown in the red box below.7. Firmware modification instructionsSpecial note *: Currently only firmware of Marlin 2.0 and above supports the SPI mode of TMC5160.Step 1:Find and open “Configuration.h” in Marlin 2.0 firmware File, and then find "# define MOTHERBOARD XXXXXX" and "XXXXX"Represents the type of board used. Confirm the motherboard you use.Step 2:Find the "pins_xxxxxx.h" file (xxxx represents the model of the board) in the Marlin \src \pins directory, and then find"X_CS_PIN", "Y_CS_PIN", "Z_CS_PIN", "EO_CS_PIN" under the file.Finally modify the following pin name to the pin youuse.Step 3:Find "#define TMC_SW_MOSI XXX", "#defineTMC_SW_MISO XXX", "#define TMC_SW_SCK XXX" underthe file in Step 2. Modify "XXX" to the pin you want to use.Step 4:Find and open "Configuration_adv.h" and then find " defineTMC_USE_SW_SPI" to remove the shield "//".Step 5:Under the "Configuration_adv.h" file, find "# defineX_CURRENT", "#define X_MICROSTEPS", "#defineX_RSENSE". After modification of the parameters (the axes used need to be modified), the RSENE of the axes usedshould be changed to "0.075"Step 6:After the modification of Step 5 is completed, find and open "Configuration. h" and then find "# define"DEFAULT_AXIS_STEPS_PER_UNIT" modifies the following parameters to set the subdivision, which must correspond tothe subdivision of step 5.Subdivision calculation method, "80, 80, 400, 96" represents 16 subdivisions. If modified to 32 subdivisions, it will be "80* (32/16), 80* (32/16), 400* (32/16), 96* (32/16).8. Driver Current DescriptionThe range of driver current depends on the value of the senseresistor.The relationship between the effective value and maximum value of the driver current and the magnitude of the sense-resistor, please see the following picture:The sense resistors used in the TMC5160-V1.0 is 0.075R, so the effective value of the driver current of this driver is 3.1A, and the maximum current is 4.4A.If you need to use a larger current, you need to replace thevalue of the sense resistor yourself (you need to prepare the components and soldering yourself). Replace the resistor not less than 0.05R (subject to module size limit).Note: It is not recommended to replace the resistor. If it must be replaced,the driver will be damaged during the replacement process is at your own risk.9. Precautions1). Always disconnect the power supply before installing thedriver to prevent the driver from burning.2). Be sure to confirm the direction of the driver before installing the driver. Prevent the driver from burning due to reverse connection.3). Please do not plug and unplug the driver module when power is on to avoid damage.4). When installing the heat sink, please be careful not to contact the heat sink and the pin header to prevent short circuit.5). The product is sensitive to static electricity, please handle it carefully when using, it is best to remove the package when using.Data download addresshttps:///bigtreetech/BIGTREETECH-TMC5160-V1.0。

The devices operate in pulse-width modulation (PWM) at a fixed frequency of 1MHz from a 2.6V to 5.5V input voltage and provide an output voltage from 0.8V to V IN , making the MAX1951/MAX1952 ideal for on-board postregula-tion applications. The high switching frequency allows for the use of smaller external components, and internal synchronous rectifiers improve efficiency and eliminate the typical Schottky free-wheeling diode. Using the on-resistance of the internal high-side MOSFET to sense switching currents eliminates current-sense resistors,further improving efficiency and cost. The MAX1951total output error over load, line, and temperature (0°C to +85°C) is less than 1%.Controller Block FunctionThe MAX1951/MAX1952 step-down converters use a PWM current-mode control scheme. An open-loop com-parator compares the integrated voltage-feedback signal against the sum of the amplified current-sense signal and the slope compensation ramp. At each rising edge of the internal clock, the internal high-side MOSFET turns on until the PWM comparator trips. During this on-time, cur-rent ramps up through the inductor, sourcing current to the output and storing energy in the inductor. The current-mode feedback system regulates the peak inductor cur-rent as a function of the output voltage error signal. Since the average inductor current is nearly the same as the peak inductor current (<30% ripple current), the circuit acts as a switch-mode transconductance amplifier. To preserve inner-loop stability and eliminate inductor stair-casing, a slope-compensation ramp is summed into the main PWM comparator. During the second half of the cycle, the internal high-side P-channel MOSFET turns off,and the internal low-side N-channel MOSFET turns on.The inductor releases the stored energy as its current ramps down while still providing current to the output. The output capacitor stores charge when the inductor current exceeds the load current, and discharges when the inductor current is lower, smoothing the voltage across the load. Under overload conditions, when the inductor current exceeds the current limit (see the Current Limit section), the high-side MOSFET does not turn on at the rising edge of the clock and the low-side MOSFET remains on to let the inductor current ramp down.Current SenseAn internal current-sense amplifier produces a current signal proportional to the voltage generated by the high-side MOSFET on-resistance and the inductor cur-rent (R DS(ON) x I LX ). The amplified current-sense signal and the internal slope compensation signal are summed together into the comparator ’s inverting input.The PWM comparator turns off the internal high-side MOSFET when this sum exceeds the output from the voltage-error amplifier.Current LimitThe internal high-side MOSFET has a current limit of 3.1A (typ). If the current flowing out of LX exceeds this limit,the high-side MOSFET turns off and the synchronous rectifier turns on. This lowers the duty cycle and causes the output voltage to droop until the current limit is no longer exceeded. A synchronous rectifier current limit of -0.6A (typ) protects the device from current flowing into LX. If the negative current limit is exceeded, the synchro-nous rectifier turns off, forcing the inductor current to flowM A X 1951/M A X 19521MHz, All-Ceramic, 2.6V to 5.5V Input,2A PWM Step-Down DC-to-DC Regulators 8_______________________________________________________________________________________through the high-side MOSFET body diode, back to the input, until the beginning of the next cycle or until the inductor current drops to zero. The MAX1951/MAX1952utilize a pulse-skip mode to prevent overheating during short-circuit output conditions. The device enters pulse-skip mode when the FB voltage drops below 300mV, lim-iting the current to 3A (typ) and reducing power dissipation. Normal operation resumes upon removal of the short-circuit condition.V CC DecouplingDue to the high switching frequency and tight output tolerance (1%), decouple V CC with a 0.1µF capacitor connected from V CC to GND, and a 10Ωresistor con-nected from V CC to IN. Place the capacitor as close to V CC as possible.Soft-StartThe MAX1951/MAX1952 employ digital soft-start circuitry to reduce supply inrush current during startup conditions.When the device exits undervoltage lockout (UVLO), shut-down mode, or restarts following a thermal-overload event, or the external pulldown on COMP is released, the digital soft-start circuitry slowly ramps up the voltages at REF and FB (see the Soft-Start Waveforms in the Typical Operating Characteristics).Undervoltage LockoutIf V CC drops below 2.25V, the UVLO circuit inhibits switching. Once V CC rises above 2.35V, the UVLO clears, and the soft-start sequence activates.Compensationand Shutdown ModeThe output of the internal transconductance voltage error amplifier connects to COMP. The normal operation voltage for COMP is 1V to 2.2V. To shut down the MAX1951/MAX1952, use an NPN bipolar junction transistor or a very low output capacitance open-drain MOSFET to pull COMP to GND. Shutdown mode causes the internal MOSFETs to stop switching, forces LX to a high-impedance state, and shorts REF to G ND.Release COMP to exit shutdown and initiate the soft-start sequence.Thermal-Overload ProtectionThermal-overload protection limits total power dissipation in the device. When the junction temperature exceeds T J = +160°C, a thermal sensor forces the device into shut-down, allowing the die to cool. The thermal sensor turns the device on again after the junction temperature cools by 15°C, resulting in a pulsed output during continuous overload conditions. Following a thermal-shutdown condi-tion, the soft-start sequence begins.Figure 1.

Connect FB to output for 0.8V output. To set the output voltage of the MAX1951 to a voltage greater than V FB (0.8V typ), connect the output to FB and G ND using a resistive divider, as shown in Figure 2a. Choose R2 between 2k Ωand 20k Ω, and set R3 according to the following equation:R3 = R2 x [(V OUT / V FB ) – 1]The MAX1951 PWM circuitry is capable of a stable min-imum duty cycle of 18%. This limits the minimum output voltage that can be generated to 0.18 ✕V IN . Instability may result for V IN /V OUT ratios below 0.18.The MAX1952 provides a preset output voltage.Connect the output to FB, as shown in Figure 2b.Output Inductor DesignUse a 2µH inductor with a minimum 2A-rated DC cur-rent for most applications. For best efficiency, use an inductor with a DC resistance of less than 20m Ωand a saturation current greater than 3A (min). See Table 2for recommended inductors and manufacturers. For most designs, derive a reasonable inductor value (L INIT ) from the following equation:L INIT = V OUT x (V IN - V OUT ) / (V IN x LIR x I OUT(MAX)x f SW )where f SW is the switching frequency (1MHz typ) of the oscillator. Keep the inductor current ripple percentage LIR between 20% and 40% of the maximum load cur-rent for the best compromise of cost, size, and perfor-mance. Calculate the maximum inductor current as:I L(MAX)= (1 + LIR / 2) x I OUT(MAX)Check the final values of the inductor with the output ripple voltage requirement. The output ripple voltage is given by:V RIPPLE = V OUT x (V IN - V OUT ) x ESR / (V IN x L FINAL x f SW )where ESR is the equivalent series resistance of the output capacitors.Input Capacitor DesignThe input filter capacitor reduces peak currents drawn from the power source and reduces noise and voltage ripple on the input caused by the circuit ’s switching.The input capacitor must meet the ripple current requirement (I RMS ) imposed by the switching currents defined by the following equation:For duty ratios less than 0.5, the input capacitor RMS current is higher than the calculated current. Therefore,use a +20% margin when calculating the RMS current at lower duty cycles. Use ceramic capacitors for their low ESR, equivalent series inductance (ESL), and lower cost. Choose a capacitor that exhibits less than 10°C temperature rise at the maximum operating RMS cur-rent for optimum long-term reliability.After determining the input capacitor, check the input ripple voltage due to capacitor discharge when the high-side MOSFET turns on. Calculate the input ripple voltage as follows:V IN_RIPPLE = (I OUT x V OUT ) / (f SW x V IN x C IN )Keep the input ripple voltage less than 3% of the input voltage.Output Capacitor DesignThe key selection parameters for the output capacitor are capacitance, ESR, ESL, and the voltage rating requirements. These affect the overall stability, output ripple voltage, and transient response of the DC-to-DC converter. The output ripple occurs due to variations in the charge stored in the output capacitor, the voltage drop due to the capacitor ’s ESR, and the voltage drop due to the capacitor ’s ESL. Calculate the output voltage ripple due to the output capacitance, ESR, and ESL as:V RIPPLE = V RIPPLE(C)+ V RIPPLE(ESR) + V RIPPLE(ESL)where the output ripple due to output capacitance,ESR, and ESL is:V RIPPLE(C)= I P-P / (8 x C OUT x f SW )V RIPPLE(ESR) = I P-P x ESRV RIPPLE(ESL)= (I P-P / t ON ) x ESL or (I P-P / t OFF ) x ESL,whichever is greater and I P-P the peak-to-peak inductor current is:I P-P = [ (V IN – V OUT ) / f SW x L) ] x V OUT / V INUse these equations for initial capacitor selection, but determine final values by testing a prototype or evalua-tion circuit. As a rule, a smaller ripple current results in less output voltage ripple. Since the inductor ripple current is a factor of the inductor value, the output voltage ripple decreases with larger inductance. Use ceramic capacitors for their low ESR and ESL at the switching frequency of the converter. The low ESL of ceramic capacitors makes ripple voltages negligible.Load transient response depends on the selected output capacitor. During a load transient, the output instantly changes by ESR x I LOAD . Before the controller can respond, the output deviates further, depending on the inductor and output capacitor values. After a short time (see the Load Transient Response graphin theM A X 1951/M A X 19521MHz, All-Ceramic, 2.6V to 5.5V Input,2A PWM Step-Down DC-to-DC Regulators 10______________________________________________________________________________________Typical Operating Characteristic s), the controller responds by regulating the output voltage back to its nominal state. The controller response time depends on the closed-loop bandwidth. A higher bandwidth yields a faster response time, thus preventing the output from deviating further from its regulating value.Compensation DesignThe double pole formed by the inductor and output capacitor of most voltage-mode controllers introduces a large phase shift, which requires an elaborate compensa-tion network to stabilize the control loop. The MAX1951/MAX1952 utilize a current-mode control scheme that reg-ulates the output voltage by forcing the required current through the external inductor, eliminating the double pole caused by the inductor and output capacitor, and greatly simplifying the compensation network. A simple type 1compensation with single compensation resistor (R 1) and compensation capacitor (C 2) creates a stable and high-bandwidth loop.An internal transconductance error amplifier compen-sates the control loop. Connect a series resistor and capacitor between COMP (the output of the error ampli-fier) and G ND to form a pole-zero pair. The external inductor, internal current-sensing circuitry, output capacitor, and the external compensation circuit deter-mine the loop system stability. Choose the inductor and output capacitor based on performance, size, and cost.Additionally, select the compensation resistor and capacitor to optimize control-loop stability. The compo-nent values shown in the typical application circuit (Figure 2) yield stable operation over a broad range of input-to-output voltages.The basic regulator loop consists of a power modulator,an output feedback divider, and an error amplifier. The power modulator has DC gain set by gmc x R LOAD ,with a pole-zero pair set by R LOAD , the output capaci-tor (C OUT ), and its ESR. The following equations define the power modulator:Modulator gain:G MOD = ∆V OUT / ∆V COMP = gmc x R LOAD Modulator pole frequency:fp MOD = 1 / (2 x πx C OUT x (R LOAD +ESR))Modulator zero frequency:fz ESR = 1 / (2 x πx C OUT x ESR)where, R LOAD = V OUT / I OUT(MAX), and gmc = 4.2S.The feedback divider has a gain of G FB = V FB / V OUT ,where V FB is equal to 0.8V. The transconductance error amplifier has a DC gain, G EA(DC),of 70dB. The com-pensation capacitor, C 2,and the output resistance of the error amplifier, R OEA (20M Ω), set the dominantpole. C 2and R 1 set a compensation zero. Calculate the dominant pole frequency as:fp EA = 1 / (2πx C C x R OEA )Determine the compensation zero frequency is:fz EA = 1 / (2πx C C x R C )For best stability and response performance, set the closed-loop unity-gain frequency much higher than the modulator pole frequency. In addition, set the closed-loop crossover unity-gain frequency less than, or equal to, 1/5 of the switching frequency. However, set the maximum zero crossing frequency to less than 1/3 of the zero frequency set by the output capacitance and its ESR when using POSCAP, SPCAP, OSCON, or other electrolytic capacitors.The loop-gain equation at the unity-gain frequency is:G EA(fc) x G MOD(fc) x V FB / V OUT = 1where G EA(fc )= gm EA x R 1, and G MOD(fc)= gmc x R LOAD x fp MOD /f C, where gm EA = 60µS .R 1calculated as:R 1= V OUT x K / (gm EA x V FB x G MOD(fc))where K is the correction factor due to the extra phase introduced by the current loop at high frequencies (>100kHz). K is related to the value of the output capacitance (see Table 1 for values of K vs. C). Set the error-amplifier compensation zero formed by R 1and C 2at the modulator pole frequency at maximum load. C 2is calculated as follows:C 2= (2 x V OUT x C OUT / (R 1 x I OUT(MAX))As the load current decreases, the modulator pole also decreases; however, the modulator gain increases accordingly, resulting in a constant closed-loop unity-gain frequency. Use the following numerical example to calculate R 1and C 2values of the typical application circuit of Figure 2a.Table 1.

The switching power stage requires particular attention. Follow these guidelines for good PC board layout:1)Place decoupling capacitors as close to the IC as possible. Keep power ground plane (connected to PG ND) and signal ground plane (connected to GND) separate.2)Connect input and output capacitors to the power ground plane; connect all other capacitors to the signal ground plane.3)Keep the high-current paths as short and wide as possible. Keep the path of switching current (C1 to IN and C1 to PG ND) short. Avoid vias in the switching paths.4)If possible, connect IN, LX, and PGND separately to a large copper area to help cool the IC to further improve efficiency and long-term reliability.5)Ensure all feedback connections are short and direct. Place the feedback resistors as close to the IC as possible.6)Route high-speed switching nodes away from sensi-tive analog areas (FB, COMP).Thermal ConsiderationsThe MAX1951 uses a fused-lead 8-pin SO package with a R THJC rating of 32°C/W. The MAX1951 EV kit layout is optimized for 1.5A. The typical application circuit shown in Figure 2c was tested with the existing MAX1951 EV kit layout at +85°C ambient temperature, and G ND lead temperature was measured at +113°C for a typical device. The estimated junction temperature was +138°C. Thermal performance can be further improved with one of the following options:1) Increase the copper areas connected to G ND, LX,and IN.2) Provide thermal vias next to G ND and IN, to the ground plane and power plane on the back side of PC board, with openings in the solder mask next to the vias to provide better thermal conduction.3) Provide forced-air cooling to further reduce case temperature.M A X 1951/M A X 19521MHz, All-Ceramic, 2.6V to 5.5V Input,2A PWM Step-Down DC-to-DC Regulators 12______________________________________________________________________________________Figure 2a.

VNQ5160KTR-E中文资料

All types of resistive, inductive and capacitive loads
Description
The VNQ5160K-E is a monolithic device made using STMicroelectronics VIPower M0-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). The device detects open load condition in both on and off states, when STAT_DIS is left open or driven low. Output shorted to VCC is detected in the off state. When STAT_DIS is driven high, the STATUS pin is in a high impedance condition. Output current limitation protects the device in overload condition. In the case of long duration overload, the device limits the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as a fault condition disappears.

Thirty-two tap points are accessible to the wiper along the resistor string between H and L. Logic inputs CS , U/D , and INC determine the position of the wiper. With CS low and U/D high, a high-to-low transition on INC increments the internal counter, increasing the resistance between W and L. When both CS and U/D are low, a high-to-low INC transition decrements the internal counter, decreas-ing the resistance between W and L. At either end (maximum or minimum positions), additional transitions in the direction of the end points will not change the counter value (the counter will not wrap around).The H and L terminals of the MAX5160 are similar to the two end terminals of a mechanical potentiometer. The tap W is equivalent to the variable tap (wiper) of the potentiometer.The MAX5161 is similar to the MAX5160 except that CS internally connects to ground and the wiper terminal (W)is shorted to the high terminal (H). The MAX5161 acts asa variable resistor (a potentiometer with the wiper and one end terminal shorted together).The MAX5160/MAX5161 feature power-on reset circuit-ry that sets the wiper position to midscale at power-up.Applications InformationThe M AX5160/M AX5161 are intended for circuits requiring digitally controlled adjustable voltage or adjustable gain, such as LCD contrast control, where voltage biasing adjusts the display contrast.Controlling a Switch-ModeLCD Bias GeneratorFigure 1 shows an application where the M AX5161 is used with a M AX1771 to make an adjustable positive LCD-bias circuit. The output of the MAX1771 is a posi-tive voltage that is digitally controlled through the M AX5160/M AX5161. Similarly, Figure 2 shows the application of the M AX5161 in a digitally controlled negative LCD-bias circuit along with the M AX774/MAX775/MAX776.Figure 1. Adjustable Positive LCD Bias Figure 2. Adjustable Negative LCD BiasM A X 5160/M A X 5161Alternative Positive LCD Bias ControlAlternatively, use an op amp to provide buffering and gain to the output of the MAX5160/MAX5161. Connect the MAX5160 to the positive input of a noninverting op amp (Figure 3) to select a portion of the input signal by digitally controlling the wiper terminal. Figure 4 shows a similar circuit for the MAX5161.Adjustable GainFigure 5 shows how to use the M AX5161 to digitally adjust the gain of a noninverting op amp configuration.Connect the MAX5161 in series with a resistor to ground to form the adjustable gain control of a noninverting amplifier. The MAX5160/MAX5161 have a low 5ppm/°C ratiometric tempco that allows for a very stable adjust-able gain configuration over temperature.Serial InterfaceFigure 6 is the serial-interface timing diagram.Low-Power Digital Potentiometers6_______________________________________________________________________________________Figure 3.
