    • The power supply controller performs the power-supply-path protection operation to restrict power supply through the switch element if a value of temperature increase of the power supply path W with respect to the reference temperature To exceeds the temperature threshold value and remove the restriction if the temperature decreases to the temperature threshold value or lower. And the controller performs the switch protection operation to restrict the power supply through the switch element if the value of the flowing current exceeds the current threshold value and remove the restriction after the reference time H elapses. And also the controller adds the additional value F to the value of temperature increase on condition that the value of the flowing current exceeds the current threshold value in the power supply protection operation and compares a post-addition temperature to the temperature threshold value.

    • With a wire protection method in accordance with the present invention, the method being used for supplying electric power from a power source to a load, an applied-current to the load is detected every predetermined time, A wire rise temperature is calculated using the detected applied-current I(n) and by a relational expression concerning heat radiation and heat generation of the wire. The calculated rise in temperature is added to a reference temperature so that a wire temperature is estimated. When the estimated wire temperature is lower than a predetermined upper limit temperature, the calculation of the rise in temperature is repeated. When the estimated wire temperature has become equal to or higher than the predetermined upper limit temperature, the electric power supply from the power source to the load is stopped so that the wire is protected.

    • An inrush current higher than a second anomaly threshold current ILfc passes through a power MOSFET 14, when a control signal S1 of low level is applied to a gate driver 28 so that the power MOSFET 14 and the like turn to a conductive state. A first forcing shutoff operation for the power MOSFET 14 is then prevented, because a first anomaly threshold current ILoc is set to an initial level higher than the inrush current. A fuse time counter 73 starts a count-up operation in response to the occurrence of the inrush current, and continues to increment its count value until a load current IL falls below the second anomaly threshold current ILfc. According to the count value, the first anomaly threshold current ILoc is decreased stepwise with time.
