9.6.5 MinSystemVoltage Register (I2C address = 0D/0Ch) [reset value based on CELL_BATPRESZ pin setting]

To set the minimum system voltage, write a 16-bit MinSystemVoltage register command (REG0x0D/0C()) using the data format listed in Figure 9-23, Table 9-27, and Table 9-28. The charger provides minimum system voltage range from 1.024 V to 16.128 V, with 256-mV step resolution. Any write below 1.024 V or above 16.128 V is ignored. Upon POR, the MinSystemVoltage register is 3.584 V for 1 S, 6.144 V for 2 S and 9.216 V for 3 S, and 12.288 V for 4 S.
