    SMBus Fan Control
    with 1°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. „
    „ „ 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 100Ω. Automatic Beta Compensation allows the user the flexibility ...
