Texas Instruments TMP709/TMP709-Q1 Trip Point Temperature Switch
Texas Instruments TMP709/TMP709-Q1 Trip Point Temperature Switch is a fully-integrated, resistor-programmable temperature switch with a temperature threshold set by just one external resistor within the entire operating range. The TMP709/TMP709-Q1 provides an open-drain, active-low output and has a 2.7V to 5.5V supply voltage range. The temperature threshold accuracy is typically ±0.5°C with a maximum of ±3 °C (60°C to 100°C). The quiescent current consumption is typically 40µA. Hysteresis is pin-selectable to 2°C or 10°C. The Texas Instruments TMP709-Q1 devices are AEC-Q100 qualified for automotive applications.
