Example Summary

This example shows the implementation of using MSPM0 to realize the MSPM0 L2 gauge solution based on MSPM0G3507 with BQ76952 EVM. After inputting a battery model and finishing parameter setting, users can get the runtime SOC with only the voltage, current and temperature input.

Device Migration Recommendations

This project was developed for a superset device included in the LP_MSPM0G3507 LaunchPad. Please visit the CCS User's Guide for information about migrating to other MSPM0 devices.

Low-Power Recommendations

TI recommends to terminate unused pins by setting the corresponding functions to GPIO and configure the pins to output low or input with internal pullup/pulldown resistor.

SysConfig allows developers to easily configure unused pins by selecting Board→Configure Unused Pins.

For more information about jumper configuration to achieve low-power using the MSPM0 LaunchPad, please visit the LP-MSPM0G3507 User's Guide.

Example Usage

This example was developed and tested based on MSPM0G3507. Please refer to the related app note for more details.
