Release Information

Overview

BQ78350 family of gauges firmware is a firmware-only release that can be flashed onto any existing BQ78350 hardware (such as the BQ78350, BQ78350-R1, BQ78350-R2, … devices). The firmware incorporates the CEDV Li-ion and LiFePO4 battery management controller to create a pack-based solution that provides a rich array of features for gas gauging, protection, authentication, and monitoring using the companion BQ769x0 family of analog front end (AFE) protection devices for upto 15-series cell Li-ion and Li-polymer battery packs.

The BQ78350-R1A device offers optional LED or LCD display configurations for capacity reporting. It also makes data available over its SMBus 1.1 interface. Battery history and diagnostic data is also kept within the device in non-volatile memory and is available over the same interface.

Features

The BQ78350-DEVICE-FW firmware is usable on any previous version of the BQ78350 hardware. Refer the release notes for more information.
