EMC1182 Datasheet PDF

SMSC EMC1182

The EMC1182 is a high accuracy, low cost, 1.8V System Management Bus (SMBus) compatible temperature sensor. 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. The EMC1182 monitors two temperature channels (one external and one internal), providing ±1°C accuracy for both external and internal diode temperatures.

FEATURES

GENERAL DESCRIPTION

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. 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.
