Application Diagrams
The highly-integrated USB20H04 Hub Controller is complemented with a minimal number of external
components to create a complete four-port Hi-Speed USB hub application. Figure 10.1 illustrates one
possible hardware configuration, but is not a complete schematic. This block diagram shows a
self-powered hub with individual over-current protection and power switching on each downstream port.
