PRODUCTION DATA.
Figure 20 shows a conceptual implementation of USB 3.1 capable Type-C DFP, used in notebook, desktop, LCD monitor or dock application where both USB data and charging is supported. USB 2.0 data lines are connected directly to Type-C receptacle while USB 3.1 data is connected through a USB 3.1 MUX. The TPS25820 controls the USB 3.1 MUX via its POL pin. In this implementation if the USB host/hub is capable of supporting BC1.2 charging then it is possible to support both BC1.2 and Type-C charging from the same Type-C port.
