Abstract
A temperature detecting circuit includes a temperature detecting unit that generates a first temperature detecting signal according to a temperature. A temperature information control unit generates a control signal by the first temperature detecting signal, supplies the control signal to the temperature detecting unit, and generates a second temperature detecting signal by the control signal and the first temperature detecting signal. A temperature information output unit generates a temperature information signal in accordance with the second temperature detecting signal and the control signal.
