Description

The EMC1822/23/24/25/43 devices are high-accuracy, 2-wire (I²C) temperature sensors with resistor

programmable system shutdown. The devices monitor up to five temperature channels. Advanced

features, such as Resistance Error Correction (REC), Beta Compensation (to support CPU diodes

requiring the BJT/Transistor model), and rate of temperature change measurement combine to provide a

robust solution for complex environmental monitoring applications.
