DESCRIPTION
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.
