EMC2101  
SMBus Fan Control  
with 1°C Accurate  
Temperature Monitoring  
Datasheet  
PRODUCT FEATURES  
GENERAL DESCRIPTION  
FEATURES  
Automatic Beta Compensation  
Resistance Error Correction  
„
„
„
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.  
Self-programming with available SMBus compatible  
EEPROM  
„
„
Selectable PWM or DAC fan driver output  
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.  
Temperature Monitors  
— External channel ±1°C accuracy  
— Internal channel ±2°C accuracy  
„
„
„
„
3.3 Volt Operation (5 Volt Tolerant Input Buffers)  
SMBus 2.0 Compliant Interface, supports TIMEOUT  
8-Pin MSOP Lead-free RoHS Compliant Packages  
8-Pin SOIC Lead-free RoHS Compliant Package  
The EMC2101 has an option to automatically upload the  
contents of an attached SMBus compatible EEPROM for  
auto-programming upon power up.  
APPLICATIONS  
Graphics Processors  
„
„
„
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 100Ω. Auto-  
matic Beta Compensation allows the user the flexibility  
to design applications that include processor substrate  
transistors.
