3 Description
The TMP302 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.
2 Applications
• Cell Phone Handsets
• Portable Media Players
• Consumer Electronics
• Servers
• Power-Supply Systems
• DC-DC Modules
• Thermal Monitoring
• Electronic Protection Systems
