2. 1 Temperature characteristics of detection voltage
The shaded area in Figure 16 shows the temperature characteristics of the detection voltage.
*1. −VDET25 is an actual detection voltage value at 25°C.
Figure 16 Temperature characteristics of detection voltage (Example for −VDET = 2.7 V)
2. 2 Temperature characteristics of release voltage
The temperature change ∆ + VDET of the release voltage is calculated by the temperature change ∆ − VDET of the
detection voltage as follows:
∆ + VDET = +VDET × ∆ − VDET
∆Ta − VDET ∆Ta
The temperature changes of the release voltage and the detection voltage have the same sign consequently.
