Table 5. Truth Table
The tri-state conditions and the status flag are reset using D1 or EN/D2. The truth table uses the following notations: L = LOW,
H = HIGH, X = HIGH or LOW, and Z = High-impedance. All output power transistors are switched off.

In the event of an under-voltage condition, the outputs tri-state and status flag is SET logic LOW. Upon under-voltage
recovery, status flag is reset automatically or automatically cleared and the outputs are restored to their original operating
condition.
When a short-circuit or over-temperature condition is detected, the power outputs are tri-state latched-OFF independent of
the input signals and the status flag is latched to logic LOW. To reset from this condition requires the toggling of either D1,
