Overview

The Bridge BoosterPack demonstrates the bq76PL455A-Q1 configured as a dedicated communications bridge to translate MCU UART  communications to the bq76PL455A-Q1 daisy chain. The bq76PL455 Bridge BoosterPack also offers  an isolated current sense input for measuring battery pack current, as well  as an isolated voltage measurement.

Features
  • BoosterPack compatible
  • Isolated current sense input for monitoring pack current
  • Isolated voltage sense input defined by the user
  • Isolated daisy chain communicaton to stacked devices
