LTC4352 - Low Voltage Ideal Diode Controller

General Description

The LTC®4352 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.
