Description
The EMC1812/13/14/15/33 devices are high-accuracy, 2-wire (I2C) temperature sensors. 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.

Multi-Channel Low-Voltage Remote Diode Sensor

Multi-Channel Low-Voltage Remote Diode Sensor Family
This device family introduces rate of change temperature measurement with associated alerts. This provides
a preemptive system alert and another protective measurement layer to catch and manage variable system
temperatures.
The Resistance Error Correction feature automatically eliminates the temperature error caused by series
resistance, allowing for greater flexibility in routing thermal diodes. Beta compensation eliminates
temperature errors caused by low, variable beta transistors common in current fine geometry processors. The
automatic beta detection feature determines the optimal sensor external diode/transistor settings. This frees
up the user from providing unique sensor configurations for each temperature monitoring application. These
advanced features plus ±1°C measurement accuracy for both external and internal diode temperatures
provide a low-cost, highly flexible and accurate solution for critical temperature monitoring applications.
