Why is the USB interface isolated The USB interface is already an electronic engineer, one of the most commonly used interfaces for daily work and practitioners. With the increasing competition in the computer industry, the price of products is getting lower and lower. Forcing most businesses to simplify and simplify the interface protection of the computer motherboard can save time. The USB interface is not only often in contact with the human body, but also many times it is also. Power from external devices. These many status quos have caused many computers' USB interfaces to strike in advance. Even the motherboard is damaged. This product is suitable for the following users: 1. Work environment with strong electricity and strong interference Some circuits contain strong electricity, strong interference (such as high voltage, inverter, motor drive, etc.) environment, When it comes to connecting with a computer, it must be isolated to ensure the computer and personal safety. 2. Noise sensitive area Everyone knows that computers are a big source of noise. In the noise sensitive field, we can isolate the USB interface through this device. Such as high-precision USB data acquisition system, HIFI sound system. 3. USB debugging device For example, various USB interface JTAG or SWD emulators, ISP or ASP or IAP or ICP downloaders, etc. When you are unable to connect during the debugging process and the simulation is abnormal, you can use the USB isolator to try to improve. 4. Various industrial control USB devices In industrial environments, USB devices often crash, such as USB mouse, keyboard, USB to serial port and other communication devices. USB isolators reduce the chance of crashes and damage to these devices in industrial environments. Sometimes it is necessary to extend the USB cable, the USB isolator can act as a very good USB repeater, and can also isolate the ground pressure difference between upstream and downstream devices.
