5 Summary

This application note provides two different kinds of fan controller designs that are based on MSPM0C1104, MSPM0C1106, MSPM0H3215, and MSPM0H3216. Both of them are controlled by an I2C bus and can perform temperature sensing and fan fault detection. The functions verified functioned well during a final test.
