MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker General Description Applications The MAX16141/MAX16141A ideal diode controllers provide system protection against a variety of system faults, such as reverse current, reverse voltage, overcurrent, input overvoltage/undervoltage, and overtemperature conditions. The wide operating voltage range of 3.5V to 36V, combined with 5μA (typ) of shutdown current, make the MAX16141/MAX16141A ideal for automotive applications. An integrated charge pump drives the gate of the back-toback external nFETs 9V (typ) above the source connection, minimizing power loss between the source and the load. ● ● ● ● ● A fast-acting comparator allows the MAX16141/ MAX16141A to block reverse-current flow within 1μs (max) of the input falling below the output voltage. An external current-sense resistor between RS and OUT provides overload monitoring capability. Two input pins, OVSET and UVSET, provide set points to protect against input overvoltage and undervoltage events using a simple resistive-divider. During startup, the MAX16141/MAX16141A monitor the voltage drop across the external nFETs (VIN - VOUT) and the load current for overcurrent fault to ensure VOUT is greater than 0.9 x VIN. Once the startup event is complete, the MAX16141/MAX16141A are ready to protect against systems faults. During normal operation, some systems experience brownouts or short interruptions of power. To ensure smooth system recovery from these interruptions, the MAX16141/MAX16141A include a secondary power input (VCC) to keep critical circuits alive. When the main input power recovers, the MAX16141/MAX16141A enable the gate in fast mode (70μs, max) to charge the output capacitor. Both devices feature a low-power mode that is enabled with a logic input. In low-power mode the devices allow limited current flow from source to the load. For the MAX16141, the low-power mode is enabled using an active-low logic input, SLEEP. For the MAX16141A, the lowpower mode is activated using an active-high logic input (SLEEP).

The MAX16141/MAX16141A consume only 5μA (typ) in shutdown mode. During a reverse-voltage condition, VOUT > VIN, the MAX16141/MAX16141A disable the gate within 1μs (max) of VIN falling below VOUT by the factory-set threshold. An internal charge pump drives the gate 9V (typ) above the source voltage to fully turn on two external back-to-back N-channel FETs, minimizing power dissipation and voltage drop across the FETs. The MAX16141/MAX16141A monitor the load current using a sense resistor between between RS and OUT and protect against reverse current flow when VIN fall below VOUT. These devices feature gate ramp rate control to provide correct operation in a variety of situations. For example, the ramp-up during power-up can be adjusted to avoid excessive inrush current. In the case of an overvoltage fault, the ramp down rate is slow enough to avoid large inductive transients when interrupting high fault currents. On the other hand, the gate drive responds quickly to transient shorts of the input to ground, thereby preventing discharge of the load-side capacitance. When the input recovers, the gate drive ramps up quickly enough to provide power to the load before the load voltage can drop excessively. Power-Up At power-up, the MAX16141/MAX16141A enable the gate drive 450μs (tSU) after the input voltage crosses the undervoltage threshold. During power-up, the gate’s rise time is determined by value of resistor connected between GRC and GND while FAULT remains low and goes high-impedance when the output voltage is greater than 90% of VIN if no fault condition is present. Undervoltage Protection The MAX16141/MAX16141A monitor the input voltage for undervoltage fault. An external resistive divider connected between TERM, UVSET, and GND sets the undervoltage threshold. (TERM is connected to VCC through a switch when SHDN is high.) When the input voltage falls below the undervoltage threshold (VCC = VIN < VUVTH - VHYS), the MAX16141/MAX16141A pull the gate voltage low, turning off the external MOSFETs, and FAULT asserts. When the input voltage rises above the undervoltage threshold (VCC = VIN > VUVTH), GATE goes high after a 450μs startup delay (typ). Overvoltage Protection The MAX16141/MAX16141A detect overvoltage conditions using an external resistive divider connected between TERM, OVSET, and GND. (TERM is connected to VCC through a switch when SHDN is high.) When the input voltage exceeds the programmed overvoltage threshold, the MAX16141/MAX16141A pull GATE to ground and isolate the load from the source voltage. The falling ramp rate of the gate voltage is determined by the value of the resistor connected between GFC and ground. See the Electrical Characteristics table for GATE’s fall times vs. resistor values. During the overvoltage fault condition, GATE latches low and FAULT stays asserted. Overvoltage/Undervoltage Threshold Hysteresis The MAX16141/MAX16141A offer six factory-set overvoltage/undervoltage threshold hysteresis options. See Figure 7 for available options. Overcurrent Protection The MAX16141/MAX16141A detect an overcurrent fault condition using a sense resistor between RS and OUT. When the load current exceeds the factory-set threshold, the MAX16141/MAX16141A isolate the load from the input and disable GATE low with a slow falling ramp rate, as selected by the resistor value between GFC and ground. See the Electrical Characteristics table for GATE’s fall times vs. resistor values. During the overcurrent fault condition, GATE enters the 300ms (typ) auto-retry mode while FAULT stays asserted. Upon on the termination of an overcurrent fault condition, the MAX16141/MAX16141A pull the gate voltage high and allow FAULT to deassert. www.analog.com Analog Devices | 15 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker The MAX16141/MAX16141A offer four factory-set overcurrent threshold options. See Figure 7 for available options. Ideal Diode Reverse-Current Protection The MAX16141/MAX16141A detect reverse-current conditions using a comparator that monitors the differential voltage between IN and OUT. When VIN falls below VOUT by the factor-set thresholds, the MAX16141/MAX16141A disable the gate drive within 1µs (max) to minimize load discharge into the source. The gate drive is enabled once the input rises above the output voltage by 50mV. The MAX16141/MAX16141A offer four factory-set reverse-current thresholds. See Figure 7 for available options. Reverse-Voltage Protection The MAX16141/MAX16141A offer reverse-voltage protection to prevent damage to the downstream circuitry caused by battery reversal or negative transients at the input. The input voltage (IN) withstands reverse voltage down to -36V below ground. When VIN is forced below ground, an internal circuit blocks the current flow from GND to IN to protect the MAX16141/MAX16141A during negative transients events. During a reverse-voltage condition, the gate drive is disabled within 1μs (max) to isolate the load from the source. Note: GATE is internally connected to SRC through a 15MΩ resistor. Connecting GATE to lower input impedance nodes forms a resistive divider between IN, GATE, and GND and keeps the external FETs on. Thermal Shutdown Protection The MAX16141/MAX16141A include thermal shutdown protection that turns off the external MOSFETs if the internal die temperature exceeds +145°C (TJ). By ensuring good thermal coupling between the MOSFETs and the MAX16141/ MAX16141A, the thermal shutdown can turn off the MOSFETs if they overheat. When the junction temperature exceeds TJ = +145°C (typ), the internal thermal sensor signals the shutdown logic, pulling the GATE voltage low and allowing the device to cool. The MAX16141/MAX16141A isolate the load from the input by pulling the gate to ground with a slow falling ramp rate to prevent transient overshoots beyond the input protection voltage and assert FAULT. When TJ drops by 15°C (typ), GATE goes high with a slow rising ramp rate and the MOSFETs turn back on. Do not exceed the absolute maximum junction-temperature rating of TJ = +150°C. GATE Ramp-Up Control To ensure proper power-up, the MAX16141/MAX16141A offer three different gate rise times set with a resistor connected from GRC to GND. See the Electrical Characteristics table for more detail. The gate’s controlled rise time ensures softstart with limited inrush current and is active during power-up, when exiting shutdown, recovering from undervoltage, overvoltage, and thermal faults. Note: The values in the Electrical Characteristics table are determined based on a 7nF gate-to-source capacitance. Depending on the gate-to-source capacitance, the rise time of the gate will be different. GATE Ramp-Down Control The MAX16141/MAX16141A control the gate fall time using a resistor from GFC to ground. See the Electrical Characteristics table for allowed resistor values. The gate’s fall-time control remains active during overvoltage, overcurrent, and thermal shutdown faults. Sleep Mode Sleep mode is a low-power mode that allows the MAX16141/MAX16141A to deliver power to the load using an internal low power MOSFET. In sleep mode, the MAX16141/MAX16141A deliver up to 400μA of current to the load while consuming only 10μA (typ). Load currents higher than 400μA force the MAX16141/MAX16141A to go into constant current mode and cause the output voltage to droop. During sleep mode, the charge pump and TERM switch are disabled. The load current flows through the internal MOSFET, SRC, and body diode of Q2. See Figure 1 for more detail. The MAX16141 features an active-low logic input (SLEEP), and the MAX16141A features an active-high logic input (SLEEP). www.analog.com Analog Devices | 16 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker VIN Q1 Q2 ISLEEP LOAD IN GATE pFET SRC OUT CHARGE PUMP MAX16141/ MAX16141A SLEEP (SLEEP) GND Figure 1. Sleep Mode Operation Note: In sleep mode, the drain of the pFET is internally clamped to 18V. Increasing the input voltage above 18V increases the sleep mode current of the device. See the Typical Operating Characteristics section for more detail. Gate Charge Pump An internal charge pump generates the GATE-to-SRC voltage to enhance the external MOSFETs. After the input voltage exceeds the input undervoltage threshold, the charge pump turns on after a 450µs startup (tSU) delay. During the reverse-voltage fault condition, GATE is disabled with a 280mA (typ) pulldown current. Upon recovery from reverse voltage, if the VCC voltage is below the undervoltage threshold, the gate drive is enabled and its ramp rate is determined by the resistor value between GRC and ground. If upon reverse-voltage recovery the VCC voltage is above the undervoltage threshold, the charge pump sources 1200μA (typ) to enable the gate drive in fast mode. Allowing the gate voltage to ramp up in fast mode helps minimize output voltage droop after reverse-voltage or short battery voltage interruptions. TERM Connection The TERM connection has an internal switch to VCC. In shutdown (SHDN = low), this switch is open. By connecting the voltage threshold resistive divider to TERM instead of directly to VCC, power dissipation in the resistive divider can be eliminated and the supply current in shutdown mode reduced. During shutdown mode, the (VCC - VTERM) can be as high as 60V, but (VTERM - VCC) must be limited to < 1V due to a parasitic diode. FAULT Output FAULT is an open-drain output that indicates fault conditions. During startup, FAULT is initially low and goes highimpedance when VOUT is greater than 90% of VIN if no fault conditions are present. FAULT asserts low during shutdown www.analog.com Analog Devices | 17 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker mode, reverse-current, overcurrent, overvoltage, thermal shutdown, or undervoltage faults, or when VOUT falls below 90% of VIN. Auto-Retry The MAX16141/MAX16141A enter auto-retry mode of 300ms (typ) during overcurrent, output short-circuit, and thermal shutdown faults. In auto-retry mode, the gate drive is enabled every 300ms (typ) to check if the fault condition is removed. If the fault is present, the gate pulls low after a short duration of 20ms (typ). If the fault condition is removed, the gate pulls high and the MAX16141/MAX16141A resume normal operation. During fault conditions, FAULT asserts low and deasserts once the fault conditions are removed. www.analog.com Analog Devices | 18 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker Applications Information Setting Overvoltage/Undervoltage Threshold The MAX16141/MAX16141A feature window-detection threshold comparators. The noninverting input of the undervoltage comparator shares the same reference voltage connected to the inverting input of the overvoltage comparator. This configuration allows using three-resistor network to set both undervoltage and overvoltage thresholds. The top of the resistive divider network connects to TERM. See Figure 2. When the input voltage falls outside the set window threshold, the gate voltage is disabled and the n-channel MOSFETs are turned off. Use the following equations to set the thresholds: [ RTOTAL VUVTH = (VTH − VTH_HYS) R2 + R3 [ VOVTH = (VTH) RTOTAL R3 ] ] where VUVTH and VOVTH are the undervoltage and overvoltage thresholds respectively, RTOTAL = R1 + R2 + R3 + RTERM, VTH is the 0.5V OVSET and UVSET threshold, and the VTH_HYS is the hysteresis, RTERM is the TERM onresistance whose typical value is 0.7kΩ. Use the following steps to determine values for R1, R2, and R3: 1. Choose a value for RTOTAL: the sum of R1, R2, R3, and RTERM. 2. Calculate R3 based on RTOTAL and the desired overvoltage threshold point, VOVTH: R3 = ( VTH × RTOTAL VOVTH ) 3. Calculate R2 based on RTOTAL, R3, and the desired undervoltage threshold point, VUVTH: R2 = ( (VTH − VTH_HYS) × RTOTAL VUVTH ) − R3 4. Calculate R1 based on RTOTAL, R2, R3, and RTERM: R1 = RTOTAL − R2 − R3 − RTERM www.analog.com Analog Devices | 19 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker Q1 VIN RSENSE Q2 COUT CIN IN D1 VOUT GATE SRC RS OUT VCC CVCC SHDN TERM MAX16141/ MAX16141A R1 UVSET R2 OVSET GND R3 Figure 2. UVSET and OVSET Threshold Setting The MAX16141/MAX16141A offer factory-set threshold hysteresis for undervoltage and overvoltage threshold settings. See Figure 7 for available options. Reverse-Voltage Protection Traditionally, discrete diodes have been used to block reverse current flow and prevent output capacitor discharge. However, for high-current applications, ideal diode controllers (FET-based solutions) are more appealing due to their low power dissipation. But, unlike a discrete diode that blocks reverse current instantaneously, a typical ideal diode controller reacts much more slowly. To prevent heavy discharge of the load-side capacitor in the case of a fault that shorts the input to ground, the MAX16141/MAX16141A disable the gate drive within 1µs (max) of detection of the reverse-voltage condition. See Figure 3. www.analog.com Analog Devices | 20 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker (VOUT - VIN) = VREV – 40mV VIN VOUT ILOAD 0A IREV VGATE 1µs (MAX) 0V Figure 3. Reverse-Voltage Fault Automotive circuits generally require supply voltage protection from various transients that occur in automotive systems. Some of these transients extend beyond the MAX16141/MAX16141A protection range. To protect against these transients, automotive systems generally use external TVSs. Figure 4 shows the recommended circuit for the MAX16141/ MAX16141A. www.analog.com Analog Devices | 21 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker Q1 VIN RSENSE Q2 VOUT COUT CIN IN GATE SRC RS OUT D1 VCC TVS1 CVCC FAULT D3 SHDN TERM MAX16141/ MAX16141A SLEEP/ SLEEP TVS2 UVSET OVSET GRC GFC GND D2 Figure 4. Recommended Reverse-Voltage Protection Circuit Ovecurrent Threshold Setting Use the following formula to set the overcurrent threshold: IOC = V(RS-OUT)/RSENSE where V(RS-OUT) is the overcurrent threshold voltage in volts, and RSENSE is the resistor in ohms connected between RS and OUT. Short Power Interruptions In an automotive environment, systems usually experience brief power interruptions where the main supply is shorted to ground. The power interruption may last for several seconds and the only source of power to system load is the output capacitance. To ensure fast recovery, an auxiliary input (VCC) helps keep the MAX16141/MAX16141A in standby mode for 100µs (typ). When the main supply input (IN) recovers, the MAX16141/MAX16141A initiate a fast recovery mode that allows the gate to reach its peak voltage within 70μs (max). See Figure 5 for more detail. Therefore, brief power supply interruptions will not affect operation of the load, as long as the load-side capacitance is sufficiently large to power the load during the interruption. www.analog.com Analog Devices | 22 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker VOUT > VIN VIN VOUT VIN > VOUT VGS = VSRC + 3.5V 100µs VGS 1µs (MAX) 70µs (TYP) Figure 5. Short Power Interruption and Recover Since VCC provides power to the MAX16141 when the main supply is shorted to ground, a low-leakage diode such as CMPD4150 from VIN to VCC and a bulk capacitance is required to keep the MAX16141/MAX16141A in standby mode. See the Typical Application Circuit for proper connection. The size of the bulk capacitance is dictated by the expected duration of the power interruption and supply current of the MAX16141/MAX16141A. Below is a simple bulk capacitance calculation for 100μs power interruption and 1V drop in VCC voltage. CVCC = (ICC × 100 × 10 − 6) ∆ VCC where CVCC is the bulk capacitance at VCC, ICC is the supply current in amperes, and ∆VCC is the desired droop in VCC in volts. (3 × 10 − 3(A) × 100 × 10 − 6(s)) ≃ 0.33μF 1V Note: If the input voltage sags slowly and the output follows, the differential voltage between the input and output may always be less than factory-set threshold. In this case, the reverse-current fault may not occur. Instead, an undervoltage fault may eventually be detected; causing the gate drive to be disabled. Gate Rise Time Control The gate rise time control connection, GRC, allows the MAX16141/MAX16141A to control the gate ramp-up rate with respect SRC. The gate rise time specifications in the Electrical Characteristics table are based on a 7nF gate-to-source capacitance. If the combined gate-to-source capacitance of the MOSFETs is higher than 7nF, the gate voltage might not reach its final nominal voltage within the internal timer selected by RGRC. As a result, upon the expiration of the internal timer, the internal charge pump increases its drive current (fast mode) to force the gate voltage to its final nominal voltage. See Figure 6 for more detail. This sudden jump in the gate voltage could cause a high dV/dt across the output capacitor and result in huge inrush current. To avoid this scenario, increase the gate rise time using a different RGRC, as specified in the Electrical Characteristics table. www.analog.com Analog Devices | 23 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker UVSET THRESHOLD VIN VOUT GATE DRIVE SWITCHES TO FAST MODE AFTER EXPIRATION OF GATE RISE TIME SET BY THE GRC RESISTOR. VGATE GATE RISE TIME > tGRC Figure 6. Gate Voltage Slow to Fast-Mode Transition MOSFET Selection MOSFET selection is critical to design a proper protection circuit. Several factors must be considered: the gate capacitance, the drain-to-source voltage rating, the on-resistance (RDS(ON)), the peak power dissipation capability, and the average power dissipation limit. In general, both MOSFETs should have the same part number. For size-constrained applications, a dual MOSFET can conserve board area. Select the drain-to-source voltage so that the MOSFETs can handle the highest voltage that might be applied to the circuit. Gate capacitance is not as critical, but it does determine the maximum turn-on and turn-off time. MOSFETs with more gate capacitance tend to respond more slowly. MOSFET Power Dissipation The RDS(ON) must be low enough to limit the MOSFET power dissipation during normal operation. Power dissipation (per MOSFET) during normal operation can be calculated using this formula: P = I2LOAD × RDS(ON) where P is the power dissipated in each MOSFET, and ILOAD is the average load current. During a fault condition in switch mode, the MOSFETs turn off and do not dissipate power. Since limiter mode can involve high switching currents when the GATE is turning on at the start of a limiting cycle (especially when the output capacitance is high), it is important to ensure the circuit does not violate the peak power rating of the MOSFETs. Check the pulse power ratings in the MOSFET data sheet. www.analog.com Analog Devices | 24 MAX16141/ MAX16141A 3.5V to 36V Ideal Diode Controllers with Voltage and Current Circuit Breaker Selector Guide MAX16141(A)__ __ __ SUFFIX OVERCURRENT THRESHOLD A 25mV B 50mV C 75mV D 100mV SUFFIX REVERSE VOLTAGE THRESHOLD SUFFIX A 10mV A 2.5/5 B 20mV B 2.5/10 C 30mV C 2.5/20 D 40mV D 5/5 E 5/10 F 5/20 OVSET/UVSET THRESHOLD HYS (%) Figure 7.
