1.8V, Resistor-Programmable Temp Switch and Analog Out Temp Sensor in SC70 (Rev. A)
Texas Instruments
Description
The TMP300 is a low-power, resistor-programmable, digital output temperature switch. It 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.The TMP300 detects temperature with ±4°C accuracy (max) over -40°C to +125°C. With a supply voltage as low as 1.8V and low current consumption, the TMP300 is ideal for power-sensitive systems. Available in two micropackages that have proven thermal characteristics, this part gives a complete and simple solution for users who need simple and reliable thermal management.
