Table 1. Truth Table
The tri-state conditions and the fault status are reset using D1 or
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).

Notes
33.
In the case of an undervoltage condition, the outputs tri-state and the fault status is SET logic LOW. Upon undervoltage recovery, fault status
is reset automatically or automatically cleared and the outputs are restored to their original operating condition.
When a short circuit or overtemperature condition is detected, the power outputs are tri-state latched-OFF independent of the input signals
and the fault status flag is SET logic LOW.
