FPF3003 IntelliMAX™ Full Functional Input Power Path Management Switch for Dual-Battery Portable System Features 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. 2.3V to 5.5V Input Voltage Operating Range Low RON between Battery and Load Maximum 50mΩ at VIN = 4.2V Low RON between Charger and Battery Maximum 125mΩ at VIN = 4.2V Maximum DC Current for Load Switch: 2.5A RESET Timer Delay: 7s Typical 1.6mm X 1.6mm, 16-Bump, 0.4mm Pitch, WLCSP Maximum DC Current for Charge Switch: 1.5A Slew Rate Controlled to 30µs Nominal Rise Time Seamless Break-Before-Make Transition Quiescent Current: 30µA Typical Thermal Shutdown Reverse Current Blocking (RCB) between Battery A and Battery B 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).
