(a) A case equipped with an input terminal, a control terminal, a power supply terminal, and a ground terminal. The input terminal is to be connected to a control voltage generator in the control unit via a harness. The control terminal is to be connected to one end of the blower motor. The power terminal is to be connected to the power source and the other end of the blower motor. (b) A power transistor built into the above case and connected between the control terminal and the ground terminal of the case. (c) A non-inverting amplifier circuit that is built into the case, is connected to the input terminal, receives a control voltage from the control voltage generator, and outputs a voltage corresponding to the control voltage. (d) A differential amplifier circuit built into the above case. One input terminal of this differential amplifier circuit is connected to the output side of the non-inverting amplifier circuit via a resistor, and is also connected to the control terminal via another resistor. Therefore, a voltage including information on the control voltage and information on the voltage at one end of the blower motor is input to this one input terminal. The other input terminal of the differential amplifier circuit is connected to a power supply terminal of the case via a resistor and to a ground terminal via another resistor. Therefore, a voltage obtained by dividing the power supply voltage by resistance is input to this other input terminal. The power transistor is controlled based on the output of the differential amplifier circuit, and thereby,
A voltage applied to both ends of the blower motor is controlled in accordance with a control voltage.
