The bq26100 provides a method to authenticate battery packs and other peripherals. The bq26100 uses a 128 bit unique device key and a 160 bit SHA-1/HMAC response to provide authentication. The device key is stored securely in each bq26100 device, allowing the host to authenticate each pack or peripheral. The purpose of the evaluation software (EVSW) is to demonstrate the functionality of the bq26100. This user's guide is intended for the operation of the software and does not necessarily explain in detail the operation of the bq26100. Refer to datasheet for any detailed information regarding operation of the device.
The EV2300 is a USB-based interface board for a PC that can be used to evaluate battery fuel gauge circuits designed with Texas Instruments' ICs. The EV2300 has connections on it for a USB cable and also accepts inputs from a battery fuel gauge circuit's communication port (SMBus or HDQ). By running the appropriate PC software for the corresponging fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit.
