USB2.0 interface protection scheme

一、Scheme protection circuit diagram

USB2.0接口保护方案


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;
