MIC284 - Two-Zone Thermal Supervisor

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.

• 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.
