Product details

Five-channel monitoring with ±1°C accuracy

The EMC1825T-2E/9R: It communicates over a 2-wire I²C/SMBus interface, running from a 1.62V to 3.6V supply rail, which means it can sit on a 1.8V logic bus without a level shifter. The 10-VFDFN package (2.5x2 mm) keeps the footprint small enough for dense PCB layouts where every mm² counts.

Feature set for power-conscious designs

Programmable limit, one-shot, standby, and shutdown modes let the designer trade off update rate against quiescent current — useful in battery-powered or thermally constrained systems where the sensor only needs to wake up on a schedule or when a threshold is crossed. The one-shot mode captures a single reading and returns to standby, cutting average power without losing the ability to poll on demand.

Frequently asked questions

Is EMC1825T-2E/9R compatible with 1.8V logic?

Yes — the supply voltage range of 1.62V to 3.6V covers 1.8V logic levels directly, so no external level translator is needed.

Is EMC1825T-2E/9R compatible with SMBus?

Yes — the output type is listed as 2-Wire Serial, I²C/SMBus, so it works on either bus.
