Introduction

In an effort to improve the reliability of large data processing, data storage and communications systems, their subsystems include a growing number of active circuits to monitor parameters such as temperature, fan speed and system voltages. Individual subsystem monitors often communicate with the host system through 2-wire serial busses, such as SMBus or I²C, to a dedicated ...
