Abstract: An overcurrent protection circuit, for example, comprises: an overcurrent detection unit configured to compare monitoring target current and an overcurrent detection threshold value; a current interruption unit configured to interrupt the monitoring target current when the monitoring target current reaches the overcurrent detection threshold value; an interruption cancellation unit configured to cancel the interruption of the monitoring target current at the elapse of a first time after the monitoring target current has reached the overcurrent detection threshold value; and a threshold control unit configured to lower the overcurrent detection threshold value at the elapse of the first time after the monitoring target current has reached the overcurrent detection threshold value.
