DESCRIPTION
The TMP709 is a fully-integrated, resistor-
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.
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.
