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 33 A supply current. Hysteresis is pin selectable to 2°C or 10°C. Ordering Information ORDER NUMBER (Pb free/Green) MARKING TEMP.
