Method and apparatus for detecting temperatures of a plurality of circuits and controlling operations based on the detected temperatures

摘要

A temperature detector includes a plurality of temperature sensors each configured to generate a voltage signal in accordance with sensed temperature and output the voltage signal, a plurality of storage circuits corresponding to the respective temperature sensors and each configured to store a signal level input to the storage circuit and output the stored signal level in response to a control signal, and a control circuit configured to exclusively select one of the voltage signals output from the respective temperature sensors, compare the selected voltage signal with a predetermined reference voltage, and store the selected voltage signal into the corresponding storage circuit sequentially in response to the control signal.
