Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The input voltage Maximum 50m at V = 4.2V IN range operates from 2.3V to 5.5V. The device selects Low R between Charger and Battery one of two batteries to provide power to the system, ON Maximum 125m at V = 4.2V enabling one battery to be charged by the external IN battery charger. Maximum DC Current for Load Switch: 2.5A The FPF3003 has battery voltage monitoring to Maximum DC Current for Charge Switch: 1.5A determine if the battery is under voltage. Special driver Slew Rate Controlled to 30s Nominal Rise Time and digital circuitry allows the device to switch quickly between battery A and battery B, which allows hot Seamless Break-Before-Make Transition swapping of battery packs. Maximum current from Quiescent Current: 30A Typical battery to load per channel is limited to a constant 2.5A and internal thermal shutdown circuits protect the part Thermal Shutdown during fault conditions. Reverse Current Blocking (RCB) between Battery A The FPF3003 is available in a 1.6mm x 1.6mm, and Battery B 16-bump, Wafer-Level Chip-Scale Package (WLCSP).
