NCP3901

Dual Input, Single Output

Power Source Multiplexer

The NCP3901 integrated circuit is a dual input, single output power

source multiplexer. It is optimized for multiplexing 2 different

charging inputs to feed a single input battery charger. To address all

types of applications, the device is able to support autonomous and

slave modes of operation. Reverse USB on−the−go is fully supported.
