High-Current Bidirectional

Load Switch with Dual Input

Support

Description

www.onsemi.com

The NCP3902 is a high voltage, high current, bidirectional load

switch. It provides input overvoltage and surge protection as well as

reverse−blocking of output voltage. The logic control of the device is

designed to interact with both a system controller and a wireless

charging receiver which allows creating a dual input charger

application with a single switch.
