Release Information

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
