출시 정보

BQ41Z90-FW is a firmware-only release that can be flashed onto any existing BQ41Z90 hardware. The firmware incorporates the patented Dynamic Impedance Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, and authentication for 2 to 16 series cell Li-ion, LiFePO 4, Li-polymer, and NiMH battery packs.

Using its integrated high-performance analog peripherals, the BQ41Z90-FW firmware measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in Li-ion, LiFePO 4, Li-polymer, and NiMH batteries and reports this information to the system host controller over an SMBus v3.2 compatible interface. SHA-1, SHA-256, and ECC authentication, with secure memory for authentication keys, enables identification of genuine battery packs.

Features

The BQ41Z90-FW firmware is usable on any previous version of the BQ41Z90 hardware
