UNDERVOLTAGE & OVERVOLTAGE CHARACTERISTICS
Limits are at -40˚C ≤ T
TRUTH TABLE
KEY TO ABBREVIATIONS
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
