3 Description

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.
