1. Description

The TMP709AIDBVR is a fully-integrated, resistorprogrammable temperature switch with a temperature threshold that is set by just one external resistor within the entire operating range. The TMP709AIDBVR 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°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 TMP709AIDBVR is available in a 5-pin, SOT-23 package.
