EMC2112 Datasheet | SMSC

RPM-Based Linear Fan Controller with Hardware Thermal Shutdown PRODUCT Features General Description The EMC2112 is an SMBus, closed-loop, RPM-based fan driver with hardware (HW) thermal shutdown and reset controller. The EMC2112 offers a single High Side fan driver capable of sourcing up to 600mA from a 5V supply. The EMC2112 utilizes Beta pensation (an implementation of the BJT or transistor model for thermal diodes) and Resistance Error Correction (REC) to accurately monitor up to three (3) external temperature zones. These Features allow great accuracy for CPU substrate thermal diodes on multiple process geometries as well as with discrete diode-connected...
