1 / 48 page  SMSC EMC1184 Revision 1.0 (07-11-13) DATASHEET Datasheet PRODUCT FEATURES EMC1184 Quad Channel 1°C Temperature Sensor with Beta Compensation and 1.8V SMBus Communications General Description 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. The EMC1184 monitors four temperature (three external and one internal) channels, providing ±1°C accuracy for both external and internal diode temperatures. 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 sett ings 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. Applications Notebook Computers Desktop Computers Industrial Embedded applications Features Programmable SMBus address 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 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 — 25°C typ, ±1°C max accuracy (20°C < TDIODE < 110°C) — 0.125°C resolution — Supports up to 2.2nF diode filter capacitor Anti-parallel diodes for extra diode support Internal Temperature Monitor — ±1°C accuracy — 0.125°C resolution 3.3V Supply Voltage 1.8V SMBus operation Programmable temperature limits for ALERT/THERM2 (85°C default high limit and 0°C default low limit) and THERM (85°C default) Available in small 10-pin 3mm x 3mm DFN RoHS compliant package * Technology covered under the US patent 7,193,543.
