Texas Instruments TMP300
The TMP300 is a low-power, resistor-programmable, digital output temperature switch. The device allows a threshold point to be set by adding an external resistor. The TMP300 has a VTEMP analog output that can be used as a testing point or in temperature-compensation loops.FEATURES
