General Description
The Fan Controller component enables designers to quickly and easily develop fan controller solutions using PSoC. The component is a system-level solution that encapsulates all necessary hardware blocks including PWMs, tachometer input capture timer, control registers, status registers and a DMA controller reducing development time and effort.
The component is customizable through a graphical user interface enabling designers to enter fan electromechanical parameters such as duty cycle-to-RPM mapping and physical fan bank organization. Performance parameters including PWM frequency and resolution as well as open or closed loop control methodology can be configured through the same user interface. Once the system parameters are entered, the component delivers the most optimal implementation saving resources within PSoC to enable integration of other thermal management and system management functionality. Easy-to-use APIs are provided to enable firmware developers to get up and running quickly.
