EMC2102
RPM-Based Fan
Controller with HW
Thermal Shutdown PRODUCT FEATURES Datasheet General Description Features 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, 28pin lead-free RoHS compliant QFN package.
The EMC2102 utilizes Beta Compensation (an
implementation of the BJT or transistor model for
thermal diodes) 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.
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.
The EMC2102 provides a stand-alone HW thermal …
