SLUS696C – JUNE 2006 – REVISED FEBRUARY 2019
bq26100 SHA-1/HMAC-based security and authentication IC with an SDQ interface
1 Features
1
3 Description
The bq26100 device 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
keyed-hash message authentication code (HMAC)
construction. A unique 128-bit key is stored in each
bq26100 device, allowing the host to authenticate
each pack.
The bq26100 device 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 device also derives
power over the SDQ bus line via an external
capacitor.
