Abstract
PURPOSE:To make it possible to constitute a temperature detecting circuit with an integrated circuit without an expensive thermistor to facilitate making the circuit small size, by constituting the circuit where the control electrode of the first field effect transistor is connected to the temperature detection signal source through a switching circuit. CONSTITUTION:The first field effect transistor 11 has source 11S, drain 11D, and gate 11G of the control electrode connected to DC power source V1, DC power source V2 through resistance 12, and DC power source V2 respectively, and further, respective electrodes 14D and 15D of the second transistor 14, which has source 14S and gate 14G of the control electrode connected to DC power source V1 and drain 11D respectively, and the third transistor 15, which has source 15S and gate 15G of the control electrode connected to DC power source V2 and drain 11D respectively, are connected to each other, thereby constituting complementary MOS inverter 13. By this constitution, it is detected whether the external air temperature is higher than the set temperature or not by the level of the high voltage generated in output terminal 16.
