Diagnostic Table
In general the status follows the input signal in normal operating conditions.
If any error is detected the status is inverted.

Note 1) Short to ground/open load/ under current /overload/short-to-supply - events shorter than min.
time td(fault) will not be latched and not reported at the diagnosis pins.
Note 2) Overload/short-to-supply - events shorter than min. time td(off) will not be latched and not
reported at the diagnosis pins.
Note 3) Off as long as overtemperature occurs, restart after cooling down.
Note 4) Shutdown latch reset by falling input edge
