Overview

BQ40Z50 family of gauges firmware is a firmware-only release that can be flashed onto any existing BQ40Z50 hardware (such as the BQ40Z50, BQ40Z50-R1, BQ40Z50-R2, … devices). The firmware incorporates the patented Impedance Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 1-series, 2-series, 3-series, and 4-series cell Li-ion and Li-polymer battery packs. Using its integrated high-performance analog peripherals, the BQ40Z50 family of gauges firmware measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in Li-ion or Li-polymer batteries and reports this information to the system host controller over an SMBus v1.1 compatible interface. SHA-1 authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
