IPC: H02M3/337
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a wire harness by stopping the power supply to a load by turning off a first overheat self-breaking semiconductor switch when it is discriminated that a prescribed current or larger one flows to the switch. SOLUTION: A temperature detecting circuit 30 connected between the gate- side terminal GA and source-side terminal SA of a first overheat self-breaking semiconductor switch QA is connected with a latch circuit 31 which continuously outputs signals upon receiving signals from the temperature detecting circuit 30. In addition, the output terminal of a latch circuit 31 is connected with the gate of an FET Q2 for breaking overheat and, when the temperature detecting circuit 30 detects that a main FET Q1 is overheated, the FET Q2 is turned on by an 'ON' signal outputted through the latch circuit 31 and the main FET Q1 is cut off by dropping the gate voltage of the FET Q1. Therefore, circuit protection can be contrived when a large current flows and the weight of a wire harness can be reduce by reducing the diameters of the wires of the harness.
