Abstract

See full text

A temperature detecting device adapted to detect temperature based on output voltage at a connection point of a thermistor and a voltage-dividing resistor, includes a temperature estimator to estimate temperature of the thermistor, a supply voltage regulator to regulate voltage supplied to the thermistor, a voltage dividing resistance regulator to regulate resistance of the voltage-dividing resistor, and a switching controller to determine whether the estimated temperature of the thermistor is in a high or low-temperature range and to control the regulators simultaneously based on the determination.
