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 III" CPU. A 2-wire serial
interface is provided to allow communication with either I
2
C"
or SMBus" masters. Features include an open-drain over-
temperature output with dedicated registers for implementing
fan control or over-temperature shutdown circuits.
Interrupt status and mask bits are provided for reduced soft-
ware 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 avail-
able-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 SilentSense" family of thermal supervisors.
