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.
