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.
