The TMP302x is a temperature switch in a micropackage (SOT563). The TMP302x offers low power (15µA max) 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 TMP302x is available in several different versions. For additional trip points, contact a TI representative
