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 FFG3105 has two Precision Voltage and Temperature Measurement programmable 64-bit registers, which can be used to enables Smart Charging Topologies store a packs identification code. The FFG3105 Low Power: < 2 A Shutdown Current monitors the cell voltage and temperature providing precise knowledge of these values. This information can 2 A Standby Current be used in charging applications to ensure optimal < 4.5 A Average Active Current performance and safety. 2 Fully Integrated I C Slave with support for Normal The FFG3105 includes an integrated temperature and Fast Modes with auto increment. sensor and battery voltage monitor. The FFG3105 also Internal BID redundancy for increased robustness includes twelve 16-bit registers which can be used to store battery parameters and recent history. A system 6-Ball, 2 x 3, 0.5 mm Pitch - Chip Scale Packaging side fuel gauge like Fairchilds FFG1040 can use these (WLCSP) registers to facilitate fast initialization following battery removal and reinsertion or for battery swaps. All Applications registers including temperature and voltage readings 2 can be accessed by the host via I C in either Standard- Battery Packs mode or Fast-mode. Mobile Devices Each Battery ID register has an internal redundant copy to improve robustness and protect against potential miss programming. The FFG3105 utilizes a 2 x 3 ball, 0.5 mm pitch, 2 WLCSP with nominal dimensions of 0.96 x 1.66 mm .
