8.7 USB PD Port Protection
End equipments like PC, Notebooks, Docking Stations, Monitors etc.. have USB PD ports which can be configured as DFP (Source), UFP (Sink) or DRP (Source+Sink). TPS25948xx can be used to as a fully integrated power path solution for USB PD ports as shown in Figure 8-22 below.
TPS25948xx provides all the basic protection functions needed on the USB power path e.g. overvoltage, overcurrent and short-circuit protection along with monitoring and control. The linear ORing mechanism in TPS25948xx ensures that there's no reverse current flowing from one power source to the other during fast or slow ramp of either supply.
