ABSTRACT:
A temperature sensor circuit is provided that facilitates preventing a too-high overshooting voltage from occurring at an output terminal when a power supply is connected to the temperature sensor circuit. The temperature sensor circuit includes a short-circuiting device, disposed in parallel to depletion mode NMOS, that short-circuits the drain and source of depletion mode NMOS when a power supply is connected; and delay device that transmits a signal for short-circuiting the drain and source of depletion mode NMOS for a certain period from the time point of power supply connection to short-circuiting device for preventing the voltage at output terminal of temperature sensor circuit from overshooting.
