Abstract

Provided is a temperature detection circuit that includes: a series connection circuit that is connected between a power supply voltage input terminal and ground and includes a temperature detection transistor and a first resistance element; and a current bypass circuit that includes a first transistor that is connected in parallel with the temperature detection element and allows a bypass current to flow therethrough. The temperature detection circuit outputs a temperature detection signal from a connection point between the temperature detection transistor and the first resistance element.
