TRUTH TABLE
1.)
In case of undervoltage tristate and status-flag are reset automatically.
2.)
Whenever overcurrent or overtemperature is detected, the fault is stored (i.e. status-flag remains low).
The tristate conditions and the status-flag 3) are reset via DI or EN.
L = Low
H = High
X = High or Low
Z = High impedance
(all output stage transistors are switched off in static state. For more inform. see next page )
