3 Description

The TMP709-Q1 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 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.
