  • The FFG3105 battery ID and smart charge monitor chip is designed for battery packs used in cell phones and other mobile devices. The FFG3105 has two programmable 64-bit registers, which can be used to store a pack’s identification code. The FFG3105 monitors the cell voltage and temperature providing precise knowledge of these values. This information can be used in charging applications to ensure optimal performance and safety.
    The FFG3105 includes an integrated temperature sensor and battery voltage monitor. The FFG3105 also includes twelve 16-bit registers which can be used to store battery parameters and recent history. A system side fuel gauge like Fairchild’s FFG1040 can use these registers to facilitate fast initialization following battery removal and reinsertion or for battery swaps. All registers including temperature and voltage readings can be accessed by the host via I2C in either Standard-mode or Fast-mode.
    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, WLCSP with nominal dimensions of 0.96 x 1.66 mm2.
