DESCRIPTION

The TMP709 is

programmable temperature switch with a temperature

threshold that is set by just one external resistor

within its entire operating range. The TMP709

provides an open-drain, active-low output and has a

2.7 V to 5.5 V supply voltage range.

fully-integrated, resistor-

Package: 5-Pin SOT23

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 TMP709 is available in a 5-pin SOT23 package.
