GENERAL DESCRIPTION
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-to back 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/MAX1...
