SHA-1/HMAC Based Security & Authentication IC W/SDQ InterfaceThe BQ26100 provides a method to authenticate battery packs, ensuring that only packs manufactured by authorized sub-contractors are used in the end application. The security is achieved using the SHA-1 hash function inside the widely adopted HMAC construction. A unique 128-bit key is stored in each BQ26100 device, allowing the host to authenticate each pack.
The BQ26100 communicates to the system over a simple one-wire bi-directional serial Interface The 5-kbits/s SDQ bus Interface reduces Communications overhead in the external Microcontroller The BQ26100 also derives power over the SDQ bus line via an external capacitor. By Texas Instruments |
