Less than six years ago, thermal cooling in the electronics arena was mainly an issue for highperformance, high-end applications, such as, military, aerospace and large-scale industrial and medical applications. Outside these sectors, thermal cooling was just a premature notion. In the short span of a few years, technological and other developments have made thermal cooling necessary for many applications, thus requiring the development of a new system management category: thermal management.This article discusses an integrated fan speed solution that provides sophisticated speed control of brushless DC fans, the most popular type of fan used in electronic equipment, and helps designers get around problems like acoustic noise, power consumption, mechanical wear-out and fault detection.
