AN89346 demonstrates how to quickly and easily develop a four-wire brushless DC fan control system using PSoC® 4. The Fan Controller Component, available in PSoC Creator™, helps to manage the fans in a variety of configurations. This application note also shows how to combine fan control and temperature sensing to create a complete thermal management solution using PSoC 4.

Introduction

System cooling is a critical component of any high-power electronic system. As circuits become smaller, increasing demands are placed on system designers to improve the efficiency of system thermal management. This requires the system cooling fans to run at the optimum speed to ensure that the system temperature is always below a defined limit. To achieve this, a temperature measurement unit and a closed-loop fan speed controller are needed.
