The MAX16171 is an ideal diode controller that protects the load against damaging automotive transients down to -42V and blocks reverse-current flow within 600ns. The MAX16171 operates over a wide supply voltage range of 4V to 57V and withstands input transients up to 76V. In light load applications, the device regulates the voltage drop across the external MOSFET to 20mV, allowing smooth, ring-free operation. At heavy load, the charge pump drives the gate of the external MOSFET into an enhanced mode of operation and significantly improves efficiency and power dissipation compared to traditionally used Schottky diodes.

The MAX16171 consumes only 1μA of current during shutdown mode (V_EN = GND) to extend battery life while providing standby power to the load through the body diode of the external MOSFET. An internal 2.5MΩ resistor between GATE and SRC keeps the external MOSFET off when the input voltage drops below ground.

The MAX16171 is available in a tiny 2mm x 3mm x 0.75mm, 8-pin TDFN package with side-wettable flanks and operates over the -40°C to +125°C automotive temperature range.

Product Details

The MAX16171 EV kit is designed to evaluate the MAX16171, an ideal diode controller that protects systems against reverse current and reverse voltage faults in automotive applications. The EV kit operates with a supply voltage range of 4V to 57V over the automotive temperature range of -40°C to +125°C. A jumper (J1) helps place the EV kit into low power shutdown mode. The EV kit PCB is available with the MAX16171ATA/VY+ installed.
