EMC1184  
Quad Channel 1°C Temperature Sensor with Beta  
Compensation and 1.8V SMBus Communications  
Datasheet  
PRODUCT FEATURES  
General Description  
Applications  
Notebook Computers  
Desktop Computers  
Industrial  
The EMC1184 is a high accuracy, low cost, 1.8V System  
Management Bus (SMBus) compatible temperature sensor.  
Advanced features such as Resistance Error Correction (REC),  
Beta Compensation (to support CPU diodes requiring the  
BJT/transistor model including 65nm and lower geometry  
processors) and automatic diode type detection combine to  
provide a robust solution for complex environmental monitoring  
applications. The ability to communicate at 1.8V SMBus levels  
provides compatible I/O for the advanced processors found in  
today’s tablet and smartphone applications.

Support for diodes requiring the BJT/transistor model

Supports 65nm and lower geometry CPU thermal  
diodes  
Pin and register compatible with EMC1414  
Automatically determines external diode type and  
optimal settings  
The EMC1184 monitors four temperature (three external and  
one internal) channels, providing ±1°C accuracy for both  
external and internal diode temperatures.  
Resistance Error Correction  
Frequency hops the remote sample frequency to reject  
DC converter and other coherent noise sources*  
Consecutive Alert queue to further reduce false Alerts  
Up to 3 External Temperature Monitors  
REC automatically eliminates the temperature error caused by  
series resistance allowing greater flexibility in routing thermal  
diodes. Frequency hopping* and analog filters ensure remote  
diode traces can be as far as eight (8) inches without degrading  
the signal. Beta Compensation eliminates temperature errors  
caused by low, variable beta transistors common in today's fine  
geometry processors. The automatic beta detection feature  
monitors the external diode/transistor and determines the  
optimum sensor settings for accurate temperature  
measurements regardless of processor technology. This frees  
the user from providing unique sensor configurations for each  
temperature monitoring application. These advanced features  
plus ±1°C measurement accuracy provide a low-cost, highly  
flexible and accurate solution for critical temperature monitoring  
applications.
