3 Description

The TMP302-Q1 family of devices is a temperature

switch in a micropackage (SOT563). The TMP302-Q1

family of devices 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-Q1 family of devices is available in

several different versions with trip points from 50ºC to

125ºC in increments of 5ºC (see the Device

Comparison Table).
