Abstract: A power supply controller includes a switch circuit to be provided between the power source and the power supply path, the switch circuit switches the power supply from the power source to the load between on and off, and a power-supply-path protection circuit. The power-supply-path protection circuit controls switching operation of the switch circuit according to a power-supply command signal that commands to start or terminate the power supply to the load, to calculate a temperature of the power-supply path, and if the calculated temperature reaches a predetermined upper limit, to inhibit the switch circuit from the power supply, thereby protecting the power-supply path. In a case where the power supply by the switch circuit is inhibited, if the temperature of the power supply path decreases to a predetermined threshold temperature, the power-supply-path protection circuit removes inhibition of the power supply by the switch circuit.

Abstract: 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.

The sleep mode setting circuit sets the power supply controller to the sleep mode according to the power-supply path satisfying a temperature condition.

Abstract: 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.

Abstract: If a power supply path is in an abnormal state, a power-supply-path protection circuit of a power supply controller inhibits a switching circuit that switches on/off power supply from a power source to a load from power supply, using data related to a protection-current temperature characteristic line set by a characteristic setting circuit. The protection-current temperature characteristic line has a characteristic in which a protection current value is constant corresponding to increase in an ambient temperature or a negative characteristic in which the protection current value reduces corresponding to increase in the ambient temperature. Within a temperature range equal to or lower than an supposed maximum ambient temperature around the power-supply-path, the protection-current temperature characteristic line and a power-supply-path temperature characteristic line have a relation that the protection-current value is equal to or lower than an allowable current value at an identical ambient temperature.
