1 Introduction

The BQ769x2 is a high integrated and accurate battery monitor device for 3-series to 16-series battery packs. The MSPM0L1306 is a highly-integrated, ultra-low power 32-bit MCU of MSPM0 family. In practice, the BQ769x2 monitor can measure battery cell voltage, temperature, and current, and reports this information to the MCU(MSPM0) through an I2C interface. The MCU can then make decisions based on the information provided by the monitor. The device can enable and disable the FETs, control the cell balancing feature, and do various responses according to specific user needs. This application note provides an I2C communication sample code for BQ769x2 base on the MSPM0L1306.
