Product details

Dual-channel temperature monitor with SMBus interface

The Microchip EMC1438-2-AP-TR is a digital temperature sensor that monitors both its own die temperature and an external diode-connected transistor via a remote channel.

Accuracy and operating envelope

The 3V to 3.6V supply rail aligns with standard 3.3V logic supplies, and the 16-QFN exposed-pad package provides a low thermal resistance path to the PCB copper plane.

Programmable features for system integration

Built-in features include a one-shot conversion mode for single readings, a programmable temperature limit with an output switch, shutdown and standby modes for power-sensitive designs.

Listed as Active on the lifecycle record with ROHS3 compliance. No EOL or LTB notices on file.

Frequently asked questions

Does EMC1438-2-AP-TR support remote temperature sensing?

Yes. The sensor monitors both its own local die temperature and an external diode-connected transistor for remote sensing, each over the full -40°C to 125°C range.
