The BQ41Z50 device, incorporating Dynamic Z-Track™ technology, is a fully integrated, single-chip, pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 2-series, 3-series, and 4-series cell Li-ion, LiPO, and LiFePO4 battery packs.
Using its integrated high-performance analog peripherals and ultra-low power 32-bit RISC processor, the BQ41Z50 device measures and maintains an accurate record of available cell capacity, voltage, current, temperature, and other critical battery parameters and reports them to the system host controller over an SMBus v3.2 compatible interface.
