VPOF,HV

Nominal power level warning thresholds (falling supply voltage) in high Voltage mode (supply on VDDH). Levels are configurable between min. and max. in increments of 100 mV.

2.7 4.2 V
VPOFTOL

Threshold voltage tolerance (applies in both normal voltage mode and high voltage mode).

-5 +5 %
VPOFHYST

Threshold voltage hysteresis (applies in both normal voltage mode and high voltage mode).
