。The operation of this embodiment is to apply a small amount of current to the thermistor 7,
It measures the change in the voltage Va across the thermistor due to changes in the internal temperature of the device and controls the drive of the fan motor 4. When the internal temperature of the device rises and the voltage Va across the thermistor falls below the reference voltage Vb, Comparator output signal 21 is H
When the igH (high) level is reached, the transistor 1 is made conductive, and the drive voltage Vc is supplied to the fan motor 4, thereby driving the fan motor 4. Therefore, it is possible to drive the fan motor 4 when the internal temperature of the device exceeds a desired temperature.
