MAX16141, MAX16141A - 3.5V to 36V Ideal Diode Controller with Voltage and Current Circuit Breaker

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. An integrated charge pump drives the gate of the back-to-back external nFETs 9V above the source connection, minimizing power loss between the source and the load.
