Abstract
A temperature detection circuit is provided with a temperature measuring circuit, a computing circuit, a temperature monitoring circuit, and a diagnostic signal generation circuit. The temperature measuring circuit outputs, to a measurement node, a temperature measurement voltage corresponding to a temperature. The computing circuit, calculates the temperature on the basis of the temperature measurement voltage. In the cases where the temperature measurement voltage is within a predetermined abnormal voltage range, the temperature monitoring circuit validates an abnormality detection signal indicating a temperature abnormality. When fault diagnosis of the temperature monitoring circuit is carried out, the diagnostic signal generation circuit supplies a diagnostic signal to the measurement node, and changes the temperature measurement voltage.
