御回路。In an auto air conditioner system for automobiles that uses a power transistor to steplessly control the rotation speed of the pro-armotor, there is a disconnection detection circuit that detects disconnection in the power transistor protection resistor connected in parallel to the power transistor, and a circuit that detects disconnection to the extent that the power transistor is not destroyed by heat. A pinch signal generation circuit forcibly drives the power transistor with a current of A pro-ar motor control circuit for an automobile, comprising a pro-ar motor rotation speed control circuit that switches to the simulated signal generation circuit side, and a disconnection state of a power transistor protection resistor is detected by the disconnection detection circuit immediately after the pro-ar switch is turned on. circuit.
