VDET = 2.7 V)

3. 2 Temperature characteristics of release voltage

The temperature change

VDET

Ta

of the release voltage is calculated by using the temperature change

VDET

Ta

of the detection voltage as follows:

Ta

The temperature change of the release voltage and the detection voltage has the same sign consequently.

3. 3 Temperature characteristics of hysteresis voltage

The temperature change of the hysteresis voltage is expressed as
