EMC2101
SMBus Fan Control
with 1В°C Accurate
Temperature Monitoring PRODUCT FEATURES Datasheet General Description Features 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. В„

В„ В„ 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. В„ В„

В„ The EMC2101 has an option to automatically upload the
contents of an attached SMBus compatible EEPROM for
auto-programming upon power up. В„ 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 100О©. Automatic Beta Compensation allows the user the flexibility …
