ADI LTC4352IMS#TRPBF

N+1 ORing 控制器N 通道

Overview

The LTC4352IMS creates a near-ideal diode using an external N-channel MOSFET. It replaces a high power Schottky diode and the associated heat sink, saving power and board area. The ideal diode function permits low loss power ORing and supply holdup applications.

The controller operates with supplies from 2.9V to 18V. For lower voltages, an external supply is needed at the VCC pin. Power passage is disabled during undervoltage or overvoltage conditions. The controller also features an open MOSFET detect circuit that flags excessive voltage drop across the pass transistor in the on state. A REV pin enables reverse current, overriding the diode behavior when desired.
