ABSTRACT:
Provided is a temperature detection circuit capable of preventing malfunction, which may occur when power is turned on. A switch circuit for giving such a potential that a comparator detects a low temperature is provided at an output terminal of a temperature sensor circuit. A switch circuit for giving such a potential that the comparator detects a low temperature is provided at an output terminal of a reference voltage circuit. When the power is turned on, each of the switch circuits is set by a switch control circuit such that the comparator detects a low temperature.
