Abstract:
With regard to a temperature sensor, a control logic circuit conducts control of the temperature sensor. During preparation of the temperature sensor, the control logic circuit reads the result of measurement of the property pertaining to the ambient temperature from the temperature sensor circuit, obtains the initial value and correction value from the result, and stores the pertinent values in the fuse memory. At times of operation of the temperature sensor, the control logic circuit reads the initial value and correction value from the fuse memory, and corrects the measurement values of the temperature sensor circuit using the pertinent values.
