G705 Global Mixed-mode Technology Inc. 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) ±3°C Threshold Accuracy (60°C to +100°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 10°C or 30°C Hysteresis SOT-23-5 Packages The G705 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 G705 provides 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 current. Hysteresis is pin selectable to 10°C or 30°C. Applications The G705 are available in 5-pin SOT-23 packages. µP Temperature Monitoring in High-Speed Computers Temperature Control Temperature Alarms Fan Control Automotive Ordering Information ORDER NUMBER MARKING TEMP.
