Overview
The TMP708 and TMP709 are fully-integrated, resistor-programmable temperature switches with
temperature thresholds that are set by just one external resistor. The TMP708/709 provide an open-drain,
active-low output and are operational over the +2.7-V to +5.5-V supply voltage range. The temperature
threshold accuracy is typically
temperature thresholds that are set by just one external resistor. The TMP708/709 provide an open-drain,
active-low output and are operational over the +2.7-V to +5.5-V supply voltage range. The temperature
threshold accuracy is typically
±
0.5
°
C with a maximum of
±
2
°
C (from +60
°
C to +100
°
C) or
±
3
°
C (from 0

to +125
°
C), and the quiescent current consumption is typically 25
μ
A. Hysteresis is pin-selectable.
The TMP708/709 are available in a 5-pin SOT-23 package. The devices are specified for operation over a
temperature range of 0
temperature range of 0
