MIC284 Two-Zone Thermal Supervisor

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. A 2-wire serial interface is provided to allow communication with either .
