TRUTH TABLE
1.)
In case of undervoltage tristate and status-flag are reset automatically.
2.)
(all output stage transistors are switched off in static state. For more inform. see next page )
Whenever overcurrent or overtemperature is detected, the fault is stored (i.e. status-flag remains low).
The tristate conditions and the status-flag

are reset via DI or EN.
