Datasheet  
PRODUCT FEATURES  
GENERAL DESCRIPTION  
FEATURES  
„
„
Beta Compensation Allows Accurate Temperature  
Measurement on 65nm CPU/GPUs  
The EMC2102 is an SMBus, closed-loop, RPM-based  
fan controller/driver with hardware (HW) thermal  
shutdown and reset controller. The EMC2102 is  
packaged in a thermally enhanced, compact, 5x5, 28-  
pin lead-free RoHS compliant QFN package.  
Closed-Loop RPM Based Fan Controller  
Accepts External Clock Source To Achieve 2%  
Accuracy  
„
„
Integrated Linear Fan Driver  
The EMC2102 utilizes Beta Compensation and  
Resistance Error Correction (REC) to accurately monitor  
three external temperature zones. These features allow  
great accuracy for CPU substrate thermal diodes on  
multiple process geometries as well as with discrete  
diode-connected transistors. Both Beta Compensation  
and REC can be disabled on the EMC2102 to maintain  
accuracy when monitoring AMD thermal diodes.  
600mA Drive Capability  
HW Thermal Shutdown (SYS_SHDN#)  
1°C Incremental Set Points For Thermal Shutdown  
Cannot be disabled by software  
„
„
Provides Reset Function (RESET#) On 5V Supply  
Three Remote Thermal Zones  
±1°C Accuracy (60°C to 100°C)  
1°C Resolution  
„
Resistance Error Correction On Thermal ‘Diode’  
Channels  
The EMC2102 includes a closed-loop RPM based Fan  
Control Algorithm that integrates a linear fan driver  
capable of sourcing 600mA of current. The fan control  
algorithm is designed to work with fans that operate up  
to 16,000 RPMs.  
Eliminates Temperature Offset Due To Series  
Resistance From PCB Traces And Thermal ‘Diode’  
„
Thermally Enhanced, 28-pin, 5x5 QFN Lead-free  
RoHS Compliant Package  
The EMC2102 provides a stand-alone HW thermal  
shutdown block. The HW thermal shutdown logic can be  
configured for a few common configurations based on  
the strapping level of the SHDN_SEL pin on the PCB.  
The HW thermal shutdown point can be set in 1°C  
increments by using a discrete resistor divider  
implemented on the TRIP_SET pin.  
„
„
Operates From Single 3.0 - 3.6V Supply  
5V Supply For Linear Fan Driver  
Software Configurable ALERT# Signal For Diode  
Fault, Fan Stall Or System Warning  
APPLICATIONS  
Notebook Computers  
„
„
„
Desktop Computers  
The EMC2102 also provides 5V supply ‘power good’  
function with a threshold of 4.5V. This function is  
provided on the RESET# pin.
