G709/G710

Resistor-Programmable SOT Temperature Switches

Features

General Description

ꢀ

±0.5°C Typical Threshold Accuracy

The G709/G710 are fully integrated, resistor pro-

grammable temperature switches with thresholds set

by an external resistor. They require only one external

resistor to set the temperature threshold within a wide

0°C to +125°C temperature range. The G709/G710

provides an open-drain, active low output. These

switches operate with a +2.7V to +5.5V single supply

while providing a temperature threshold accuracy of

±0.5°C (typ) or ±3.5°C (max). They typically consume

33ꢀA supply current. Hysteresis is pin selectable to

2°C or 10°C.
