Under-voltage RESET Threshold Voltage
Device is functional provided T
Over-voltage thresholds minimum and maximum include hysteresis.
Under-voltage thresholds minimum and maximum include hysteresis, for disabling outputs only, RESET based on VCC under-voltage
This parameter is guaranteed by design, however is not production tested.
Output fault detect thresholds are the same for output open and shorts.
