General Description
The G705 are fully integrated, resistor programmable
temperature switches with thresholds set by an ex-
ternal resistor. They require only one external resis-
tor to set the temperature threshold within a wide
0°C to +125°C temperature range. The G705 pro-
vides an open-drain, active low output. These
switches operate with a +4V to +5.5V single supply
while providing a temperature threshold accuracy of
±0.5°C (TYP) or ±3.5°C (MAX) or ±3°C (60°C to
+100°C). They typically consume 33µA supply cur-
rent. Hysteresis is pin selectable to 10°C or 30°C.
The G705 are available in 5-pin SOT-23 packages.
