General Description
The MIC384 is a versatile digital thermal supervisor capable
of measuring temperature using its own internal sensor and
two inexpensive external sensors or embedded silicon diodes
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. The open-drain interrupt output
pin can be used as either an over-temperature alarm or a
thermostatic control signal.
Interrupt mask and status bits are provided for reduced soft-
ware overhead. Fault queues prevent nuisance tripping due
to thermal or electrical noise. A programmable address pin
permits two devices to share the bus. (Alternate base ad-
dresses available contact Micrel.) Superior performance,
low power and small size makes the MIC384 an excellent
choice for multiple zone thermal management applications.
