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 I2C** or SMBus* masters. The open-drain interrupt output pin can be used as either an over-temperature alarm or a thermostatic control signal.
