Overview
The BQ27Z746-DEVICE-FW is a firmware (FW)-only release that can be flashed onto any existing hardware such as BQ27Z746 product. 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, differential battery sensing analog output, and authentication for 1-series cell li-ion and li-polymer battery packs.
Using its integrated high-performance analog peripherals, the BQ27Z746-DEVICE-FW firmware enables the device and 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. The integrated protection provide safety protection against Over Voltage (OVP), Under Voltage (UVP), Over Current in Charge/Discharge (OCC/OCD), Short Circuit Discharge (SCD), and Battery Sensing Protections (BCP, BCN, BDP and BDN).
SHA-2 authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
BQ27Z746-DEVICE-FW is usable on any previous version of the BQ27Z746 hardware.
