1 Introduction

The bq76PL455A-Q1 can be stacked vertically to monitor up to 192 cells without additional isolation components between ICs. A high-speed universal asynchronous receiver/transmitter (UART) bus operates between the bottom bq76PL455A-Q1 and the TMS570LS0432 microcontroller. The differential communication interface provided by the bq76PL455A-Q1 is used to provide reliable communications through all bq76PL455A-Q1 devices in a high-voltage battery cell stack.

This firmware provided with this application note provides source code examples of the command sequences described in the bq76PL455A-Q1 Software Design Reference document (SLVA617).

Sample application code and other information associated with this application report can be downloaded from SLUC270.
