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).
