Dual-Battery Portable Equipment
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).
