DESCRIPTION

The 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.
