3 Description
The TMP708 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 TMP708
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 10°C or 30°C.
The TMP708 is available in a 5-pin, SOT-23 package.
