The direct charging waterproof interface type c16p pin definition female IPX8 waterproof capability USB Type-C provides many features, including advanced flexibility and convenience for end users. System designers must carefully choose the options provided, so as to control the overall system cost within a reasonable range. There are two options that will have the greatest impact on the cost and complexity of the system, one is the inherent power of Type-C of 15W, and the other is to enhance power supply capacity and video support. USB Type-C port and minimize its impact on existing systems as much as possible. USB Type-C devices are also becoming increasingly popular in the real world, and many popular phones and tablets use USB Type-C interfaces. I expect the number of products using USB Type-C interfaces to rapidly increase in the coming years. Why is the USB Type-C capable of providing greater power than any previous USB version, with a power of 15W (5V3A) and a plug that can be inserted both forward and backward. Although USB Type-C can support up to 100W of power for USB 3.1 and USB charging, system designers must carefully select features to maintain a reasonable overall cost. The USB Type-C interface uses 15W power, which is six times the standard USB 2.0 charging rate. For most smartphones and tablets, 15W is sufficient. With the launch of the new generation of Type C connector interfaces on flagship phones of major brands, Type C interfaces are gradually entering our lives, and hosts and devices that support USB 3.1 are also becoming increasingly widespread. Although USB 3.0/3.1 is simpler in terms of testing steps than USB 2.0 HS/FS and LS,
