Release Infomation

Overview

BQ40Z50-DEVICE-FW is a firmware-only release that can be flashed onto any existing BQ40Z50 hardware ( such as the BQ40Z50, BQ40Z50-R1, BQ40Z50-R2, … device ). 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-DEVICE-FW 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.

Features

The BQ40Z50-DEVICE-FW firmware is usable on any previous version of the BQ40Z50 hardware

Release Infomation

Overview

Several TI Fuel Gauge products support authentication for anti-counterfeit protection of battery packs. The selection of the battery authentication scheme between SHA and ECC is left to the user to decide. bqKeyPackager is provided to package the key, and bqKeyProgrammer is provided to program the key onto the selected gauge. The purpose of these two standalone tools is to allow an OEM to encrypt authentication keys in a file and send to a packmaker. The packmaker can then use this file as the data source for bqKeyProgrammer to program the key(s) into a gauge. The key will not be visible to the packmaker.

Features

Supports multiple TI gauge devices that support authentication

Supports SHA1, SHA256, and ECC key packaging depending on the device

Keeps key hidden from packmaker for additional security in the manufacturing process

Requires EV2300, EV2400 or MKST-3P-ALT-EV2300
