BQ26100 - Battery Pack Security Authentication

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.

Features

  • 1 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 2.
