A circuit device includes: a plurality of circuit blocks, each circuit block being provided with at least one temperature sensor; and a control circuit controlling the plurality of circuit blocks. Each circuit block performs first feedback control for temperature abnormality detection, based on a temperature detection value of the temperature sensor provided in each circuit block. The control circuit performs second feedback control for temperature abnormality detection to each circuit block of the plurality of circuit blocks, based on the temperature detection value of the temperature sensor.
