Release Information

Description

The R1B version of BQ28Z610-DEVICE-FW is a firmware (FW) upgrade for the BQ78Z100 hardware. It is identical to BQ28Z610-R1. Programming the R1B firmware on BQ78Z100 hardware will effectively convert the BQ78Z100 to a BQ28Z610-R1(Rev. A). BQ28Z610-R1 is a highly integrated, accurate, 1-series to 2-series cell gas gauge with protection solution, providing autonomous charger control and cell balancing. This firmware is compatible with bq28z610-R1 hardware. Note: This firmware is not compatible with bq28z610 hardware.

Features

  • Autonomous battery charging control, using a dedicated Main mode I²C interface
  • Cell balancing with an internal bypass to optimize battery health
  • A high-side protection N-channel FET drive enables serial bus communication during fault conditions
  • Programmable protection levels for voltage, current and temperature
  • Support for simultaneous current and voltage sampling
  • Supports battery trip point (BTP) function for Windows integration
  • SHA-1 authentication responder for increased battery pack security
  • 400-kHz I²C bus communications interface for high-speed programming and data access

What's new

  • Identical to BQ28Z610 R1 (Rev. A)
