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 di-
odes 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
software 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
addresses available – contact Micrel.) Superior perfor-
mance, low power and small size makes the MIC384 an
excellent choice for multiple zone thermal management
applications.
