Why isolate the USB interface?
The USB interface is already one of the most commonly used interfaces for electronic engineers and practitioners in their daily work and life. With the increasing competition in the computer industry, the price of products is getting lower and lower,
Forcing most businesses to simplify the interface protection part of the computer motherboard if it can be simplified, and save it if it can be saved. The USB interface not only often comes into contact with the human body and the outside, but also it is often used for
External device power supply. These many status quo have led to the early strike of the USB interface of many computers. 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 and strong interference (such as high-voltage electricity, inverter, motor drive, etc.) environment,
When it comes to connecting with a computer, it must be isolated to ensure computer and personal safety.
2. Noise sensitive areas
We all know that computers are a big source of noise. In noise-sensitive areas, we can use this device to isolate the USB interface for communication. Such as high-precision USB data acquisition system, HIFI audio system.
3. USB debugging device
For example, JTAG/SWD emulators of various USB interfaces, ISP/ASP/IAP/ICP downloaders, etc. When you are often unable to connect and the simulation is abnormal during the debugging process, you can use a USB isolator to try to improve.
4. Various industrial control USB devices
In an industrial environment, USB devices often crash, such as USB mouse, keyboard, USB-to-serial and other communication devices. USB isolators can effectively reduce the chances of freezing and damaging these devices in industrial environments.
Sometimes it is necessary to extend the USB cable, and the USB isolator can act as a very good USB repeater, and can also isolate the ground voltage difference between upstream and downstream devices.
5. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.
6. Medical equipment
The safety of the human body is the most important and primary consideration, but some medical equipment is connected to the computer through the USB interface. In the process of collecting data on the human body, it is necessary to have direct electrical contact with the human body.
To avoid electric shock caused by the high voltage that may be conducted from the computer to the human body through the equipment and interface lines, the electrical isolation of the interface lines has become one of the important protective measures.
