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. Two levels of hysteresis are available. The TMP300 has a VTEMP analog output that can be used as a testing point or in temperature-compensation loops.Available in two micropackages with proven thermal characteristics, low current consumption, and a supply voltage as low as 1.8 V, the TMP300 is designed for power-sensitive systems that require simple and reliable thermal management.
