AN66627 describes how to configure PSoC 3 and PSoC 5 applications to independently control up to 16 fans in a single device.
This application note demonstrates how to quickly and easily develop fan control/management systems using the supplied FanController system-level component. The component supports up to 16 pulse width modulator (PWM) controlled 4-wire fans and through an intuitive graphical interface, enables designers to quickly configure the number of fans, their electromechanical properties, organization into banks (if desired) and the control algorithm type - firmware or hardware based.
