Device Overview

Summary

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. Interrupt mask and status bits are provided for reduced software overhead. Fault queues prevent nuisance tripping due to thermal or electrical noise. 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 the MIC384 an excellent choice for multiple zone thermal management applications. *SMBus and Pentium III are trademarks of Intel Corporation. **I2C is a trademark of Philips Electronics, N.V.
