    PRODUCT FEATURES Datasheet General Description Features The EMC2105 is an SMBus compliant fan controller with
    up to five (up to 4 external and 1 internal) temperature
    channels. The fan driver can be operated using two
    methods each with two modes. The methods include an
    RPM based Fan Speed Control Algorithm and a direct
    drive setting. The modes include manually programming
    the desired settings or using the internal programmable
    temperature look-up table to select the desired setting
    based on measured temperature.
    The temperature monitors offer 1В°C accuracy (for
    external diodes) with sophisticated features to reduce
    errors introduced by series resistance and beta variation
    of substrate thermal diode transistors commonly found
    in processors.
    The EMC2105 also includes a hardware programmable
    temperature limit and dedicated system shutdown
    output for thermal protection of critical circuitry. Applications
