Abstract: An overcurrent protection apparatus that protects, from overcurrent, a load circuit including an electric load and wiring electrically connected with each other is provided. The overcurrent protection apparatus includes: a semiconductor switching element that is configured to control energization to the load circuit; and a breaker that stops the semiconductor switching element upon detection of abnormality of overheat or overcurrent at the semiconductor switching element, the breaker having a latch operation mode of continuously stopping the semiconductor switching element even upon cancellation of abnormality detection, and a retry operation mode of canceling stoppage of the semiconductor switching element upon the cancellation of the abnormality detection. The breaker is configured to initially operate in the latch operation mode upon the abnormality detection, and then be switched to the retry operation mode after satisfaction of a predetermined condition.

Abstract: An overcurrent protection circuit includes a load drive portion that drives a load based on a power supply voltage; a wire that connects the load and the load drive portion; a current detection portion that detects a load current showing a value of a current flowing through the load; a voltage detection portion; and a controller that controls the load drive portion to control a drive of the load, the controller determining an addition-and-subtraction value, controlling the load drive portion to cut off the load current, and stopping driving the load to protect a protection target from an overcurrent.
