Purpose | Battery Authorization |
The bq26100 deviceprovides a method to authenticate battery packs, ensuring that only packs manufactured byauthorized sub-contractors are used in the end application. The security is achieved using theSHA-1 hash function inside the widely adopted keyed-hash message authentication code (HMAC)construction. A unique 128-bit key is stored in each bq26100 device, allowing the host to authenticate eachpack.
The bq26100 devicecommunicates to the system over a simple one-wire bi-directional serial interface. The 5-kbits/sSDQ bus interface reduces communications overhead in the external microcontroller. Thebq26100 device also derivespower over the SDQ bus line via an external capacitor.
