Diagnosis

Various errors as listed in the table “Diagnosis” are detected. Short circuits and overload

result in turning off the output stages after a delay

t

simultaneously [EF = L]. Changing the inputs to a state where the fault is not detectable

resets the error flag (input toggling) with the exception of short circuit from OUT1 to

OUT2 (load short circuit).
