A 2-wire serial interface is provided to allow munication with either I2C or SMBus servers. Features include an open-drain overtemperature output with dedicated registers for implementing fan control or overtemperature 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 are available by contacting Microchip. Superior performance, low power, and small size makes the MIC284 an excellent choice for the most demanding thermal management applications. The MIC284 is part of the Silent Sense family of thermal supervisors.
