Abstract
An abnormal current protection device includes an overcurrent protector and a controller, and the overcurrent protector includes a short-circuit detection unit and an overcurrent detection unit. The short-circuit detection unit is configured to detect whether there is a short-circuit event within a period of debounce time of a protection cycle. The overcurrent detection unit is configured to detect whether there is an overcurrent event after the period of debounce time within the protection cycle. The controller is configured to disable a converter when the short-circuit event is detected, and disable a power stage when the overcurrent event is detected.
