BQ26100
- Provides authentication of battery packs through SHA-1 engine based HMAC
- 160-byte one-time programmable (OTP), 16-bytes EEPROM
- Internal time-base eliminates external crystal oscillator
- Low-power operating modes:
- Active: < 50 µA
- Sleep: 8 µA typical
- Single-wire SDQ interface
- Powers directly from the communication bus
- 6-lead VSON package
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.
