A temperature sensor circuit includes a temperature detecting circuit, a preset value storing circuit, and a current supplying circuit. The temperature detecting circuit is configured to generate a first temperature voltage in accordance with an ambient temperature and a current. The preset value storing circuit stores a second temperature voltage preset for a predetermined ambient temperature as a digital value. The current supplying circuit supplies the current to the temperature detecting circuit. The current supplying circuit supplies the current such that the first temperature voltage generated by the temperature detecting circuit at the predetermined ambient temperature is equal to the second temperature voltage.
