2. Reference voltage circuit
3. Comparator
4. Other characteristics
The S-807 Series has 0.8 V typical reference voltage circuit as-
V
It features:
The comparator drives a differential amplifier with a current
consumption of only 0.5 A as shown in Figure 15.
It features:
(1) Temperature characteristic of detection voltage
(2) Temperature characteristic of release voltage
REF
Low power consumption
Good temperature characteristic
Good matching characteristics
Wide operating voltage range
Low offset voltage
(a high-stable reference voltage source) .
Because of the excellent temperature characteristic of the reference voltage circuit, the temperature characteristics of
the detection voltage are expressed by the following formula in the range of -30 C to +80 C.
