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.
