When the device 10 detects the overheating state of the drive circuit while the circuit is in the active state, the device 10 limits the power supply to the load by canceling the active state, and monitors the overhearing state synchronously to a timing signal 102 having a prescribed period by maintaining a power limiting and controlling state. When the device 10 detects the cancellation of the overheating state while the device 10 monitors the overheating state, the device 10 generates a gate control signal 108a for canceling the power limiting and controlling state.  Therefore, the power limiting and controlling state can be canceled immediately by using the gate control signal 108a synchronized to a reset signals 110a.
