Note 1: All Under-voltage Lockout, Overvoltage measurements are referenced to the AVIN Input and GND Pins.
Note 2: This delay can be affected by programming sequence and startup delays.
Note 3: All POK Under-voltage and Overvoltage measurements are referenced to the VIN Input and GND Pins.
Note 4: There is no hysteresis on OV and UV threshold for the POK interrupt.
