1 / 57 page  SMSC EMC2101 Revision 2.54 (06-16-09) DATASHEET Datasheet PRODUCT FEATURES EMC2101 SMBus Fan Control with 1°C Accurate Temperature Monitoring General Description The EMC2101 is an SMBus 2.0 compliant, integrated fan control solution complete with two temperature monitors, one external and one internal. Each temperature channel has programmable high limits that can assert an interrupt. The fan drive is selectable as a Pulse Width Modulator (PWM) or Linear (DAC) output. The fan control output, whether the PWM or DAC drive circuit, uses an eight position look-up table to allow the user to program the fan speed profile based on temperature. The DAC out- put ranges from 0V to VDD with up to 6 bit resolution while the PWM output has a range of 0% to 100% with up to 64 steps. The EMC2101 has an option to automatically upload the contents of an attached SMBus compatible EEPROM for auto-programming upon power up. Advanced thermal sensing enables reduced validation and characterization time as well as accurately operat- ing with smaller-geometry processors. Resistance Error Correction (REC) automatically corrects the offset errors of board trace and device resistance, up to 100 Ω. Auto- matic Beta Compensation allows the user the flexibility to design applications that include processor substrate transistors.
