Abstract:
A device is provided that includes a power transistor and an overcurrent detection logic. The overcurrent detection logic has a first stable state providing a first signal level on a status output terminal and a second stable state providing a second signal level on the status output terminal. The overcurrent detection logic changes from the first stable state to the second stable state in response to detecting that a current through the power transistor exceeds a current limit. The overcurrent detection logic remains in the second state when the current through the transistor drops below the limit after exceeding the current limit.
