Power Path Management 16-Pin WLCSP T/R

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 path during fault conditions. The FPF3003 is available in a 1.6mm x 1.6mm, 16-bump, Wafer-Level Chip-Scale Package (WLCSP).
