The TMP709-Q1 is a fully-integrated, resistor- programmable temperature switch with a temperature threshold that is set by just one external resistor within the entire operating range. The TMP709-Q1 provides an open-drain, active-low output and has a 2.7-V to 5.5-V supply-voltage range.

The temperature threshold accuracy is typically ±0.5°C, with a maximum of ±3.5°C (60°C to 100°C). The quiescent current consumption is typically 40 µA. Hysteresis is pin-selectable to 2°C or 10°C.

The TMP709-Q1 is available in a 5-pin, SOT-23 package.
