    Two-Zone Thermal Supervisor General Description
    The MIC284 is a versatile digital thermal supervisor capable of
    measuring temperature using its own internal sensor and an
    inexpensive external sensor or embedded silicon diode such
    as those found in the Intel Pentium IIIв„ў CPU. A 2-wire serial
    interface is provided to allow communication with either I2Cв„ў
    or SMBusв„ў masters. Features include an open-drain overtemperature output with dedicated registers for implementing
    fan control or over-temperature shutdown circuits.
    Interrupt status and mask bits are provided for reduced software overhead. The open-drain interrupt output pin can be
    used as either an overtemperature alarm or a thermostatic
    control signal. A programmable address pin permits two
    devices to share the bus. (Alternate base addresses available-contact Micrel.) Superior performance, low power and
    small size makes the MIC284 an excellent choice for the most
    demanding thermal management applications. The MIC284
    is part of the SilentSenseв„ў family of thermal supervisors.
