一、Scheme protection circuit diagram

二、Application background
1. All devices using USB2.0
三、Explanation of the plan
1. The power supply adopts OVE2632A1,5V/15pF/DFN1006 packaged high-current low-clamping device;
2. The maximum speed of the signal line of the USB2.0 interface is up to 480M, and it is necessary to use low-capacity components, and choose OVEL532A1, 5V/0.5pF/DFN1006 package to protect high-speed signals;
