The fault condition is reported on the DIAG pin. The internal cut-off flag signal is latched at output switch-off and

The status of the DIAG is independent on the IN pin status.

If CoD pin is connected to GND through 1 kΩ resistor (cut-off feature disabled), when the output channel triggers

the limitation threshold, it remains on, in current limitation condition, until the input becomes LOW or the thermal

protection threshold is triggered.
