TBFOn MITO 8M Mini/Nano there is an Analog to Digital converter that could be used as a voltage monitor for the PMIC voltage rails.
=== Description ===It is connected to the AMUX output from PMIC. See [https://www.nxp.com/docs/en/data-sheet/PF8121.pdf PMIC PF8121] datasheet for more details.
TBDThe ADC component is a Texas Instruments ADS1114:* 16 bits resolution* Programmable Data Rate: 8 SPS to 860 SPS* Low Current Consumption: 150 µA (Continuous-Conversion Mode)It is connected to the internal I2C1.
