Description

The FPF3003 is a single-chip solution for dual-battery

power-path switching, including integrated P-channel

switches and analog control features. The input voltage

range operates from 2.3V to 5.5V. The device selects

one of two batteries to provide power to the system,

enabling one battery to be charged by the external

battery charger.

The FPF3003 has battery voltage monitoring to

determine if the battery is under voltage. Special driver

and digital circuitry allows the device to switch quickly

between battery A and battery B, which allows hot

swapping of battery packs. Maximum current from

battery to load per channel is limited to a constant 2.5A

and internal thermal shutdown circuits protect the part

during fault conditions.

The FPF3003 is available in a 1.6mm x 1.6mm,

16-bump, Wafer-Level Chip-Scale Package (WLCSP).
