摘要
A circuit apparatus for controlling the temperature-dependency of the load current for controlling current as a temperature function through a fan motor is provided to adjust the current as a temperature function through the fan motor and reduce a manufacturing cost. Load current flows in a resistance(RS). The voltage(VS) serving of the control variable is fallen for the adjustment of the load current. The tapping point(P) for the reference voltage(Vref) performs the role of the command argument for the adjustment of the load current. The differential amplifier amplifies the system deviation(Vref - VS). A differential amplifier includes a first and a second transistor(Q1, Q2) as a temperature function for the adjustment of the load current(IL).
