TIDA-01400
Battery Pack Controller Communications Bridge Reference Design
TIDA-01400
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
