3 Description

The TMP302 device is a temperature switch in a

micropackage (SOT563). The TMP302 offers low

power (15-μA maximum) and ease-of-use through

pin-selectable trip points and hysteresis.

These devices require no additional components for

operation;

they

can

function

independent

of

microprocessors or microcontrollers.

The TMP302 is available in several different versions.

For additional trip points, contact a TI representative.
