Microchip EMC1843T-1E-RW 3-Channel I2C Temperature Sensor 1.8V WDFN

Technical description of the product (EMC1843T-1E-RW):

Microchip EMC1843 is a 1.8V, 3-channel, high accuracy, 2-Wire (I2C compatible) temperature sensor in an 8 WDFN 2x2x0.8mm package. Advanced features include Rate of Change, Shutdown, Resistance Error Correction (REC), Beta Compensation (for CPU diodes requiring BJT/transistor model), and Ideality Configuration for robust environmental monitoring. The EMC1843 introduces rate of change functionality, providing data for preemptive system control and better temperature regulation. A resistor-settable shutdown temperature protects against brownout. Resistance Error Correction automatically eliminates temperature errors from series resistance, allowing flexible thermal diode routing. Beta Compensation eliminates temperature errors from low, variable beta transistors in modern processors, simplifying sensor configurations. These advanced features, plus ±1° measurement accuracy, offer a low-cost, flexible, and accurate solution for critical temperature monitoring.
