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

output 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

operating

with

smaller-geometry

processors.

Resistance Error Correction (REC) automatically

corrects the offset errors of board trace and device

resistance, up to 100

. Automatic Beta Compensation

allows the user the flexibility to design applications that

include processor substrate transistors.
