L logic low UV undervoltage

H logic high OV overvoltage

X don’t care LC low current or open circuit load

0 condition not present SC short circuit

1 condition present OT overtemperature

1 Undervoltage sensor causes the device to switch off and reset.

2 Overvoltage sensor causes the device to switch off to protect its load.

3 The status will continue to indicate OT (even if the input goes low) until the device cools below the reset threshold. Refer to OVERLOAD
