Description

The TMP300B-Q1 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 TMP300B-Q1 has a VTEMP analog output that can be used as a testing point or in temperature-compensation loops.

With a supply voltage as low as 1.8V and low current consumption, the TMP300B-Q1 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.
