Battery pack and cell voltages can be read through a few different registers in the MAX17201:
- VCell Register (0x09)
- Reports the lowest reading from all cell voltage measurements. See page 70 of the datasheet* for more information.
- Reports the lowest reading from all cell voltage measurements. See page 70 of the datasheet* for more information.
- AvgVCell Register (0x19)
- Reports the average of all VCell register readings. See page 70 of the datasheet* for more information.
- Reports the average of all VCell register readings. See page 70 of the datasheet* for more information.
- Cell1 (0xD8), Cell2 (0xD7), Cell3 (0xD6), Cell4 (0xD5) Registers
- Each reports the measured voltage for the noted cell. There are multiple configurations for these registers. Please read page 71 of the datasheet* for more information.
- Each reports the measured voltage for the noted cell. There are multiple configurations for these registers. Please read page 71 of the datasheet* for more information.
- Batt Register (0xDA)
- Reports the voltage of the entire cell stack. See page 71 of the datasheet* for more information.
