Microchip Technology MIC284
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. The open-drain interrupt output pin can be used as either an overtemperature alarm or a thermostatic control signal. Superior performance, low power, and small size makes the MIC284 an excellent choice for the most demanding thermal management applications.FEATURES
