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).

The FPF3003 is a low-RON, P-channel-based, inputsource-selection power management switch for dualbattery systems. The FPF3003 input operating range is from 2.3V to 5.5V on BATA and BATB, while ADPIN has a range of 4.6V to 5.5V. Battery Selection The load path can be controlled by the BATSEL pin. When BATSEL is LOW, the system is powered from BATA. When BATSEL is HIGH, BATB powers the system. Figure 36 is state diagram showing how the power path from battery to system is determined.
PAGE 15
System RESET The charging path can be controlled by the CHGSEL pin. When CHGSEL is LOW, BATA can be charged from the charger. When CHGSEL is HIGH, BATB can be charged from the charger. The RESETB pin allows the system to be turned off without detaching the battery pack. It has typical 7s delay to avoid transient abnormal signal.
