G709/G710 Global Mixed-mode Technology Resistor-Programmable SOT Temperature Switches Features General Description ±0.5°C Typical Threshold Accuracy ±3.5°C (max) Threshold Accuracy (0°C to +125°C) Temperature Threshold Set by a 1% External Resistor Low 33µA Supply Current Open-Drain Active Low Output Stage Guaranteed Reset Valid to VCC = 0.8V Pin-Selectable 2°C or 10°C Hysteresis SOT-23-5, SOT-23-6, TDFN2X2-8 and ADFN1.5X1.5-6 Packages The G709/G710 are fully integrated, resistor programmable 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 33µA supply current. Hysteresis is pin selectable to 2°C or 10°C.
