5.Application:
1>.Strong electricity, strong interference working environment: Some circuits contain strong electricity, strong interference (such as high voltage, inverter, motor drive, etc.) environment, when it is connected to the computer, must be isolated to ensure computer, personal safety.
2>.Noise sensitive area: The computer is 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/SWD emulators, ISP/ASP/IAP/ICP downloaders, etc. When you often can't connect during the debugging process, you can use the USB isolator to try to improve when the simulation is abnormal.
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.
5>.USB peripheral: Such as mouse, keyboard, USB sound card, USB flash disk, printer, digital camera, USB HUB, USB camera,etc.
6>.Medical equipment: The safety of the human body is the most important and primary consideration, but some medical devices are connected to the computer through the USB interface. In the process of collecting data or treatment for the human body, it is necessary to have direct electrical contact with the human body, and to avoid possible passage from the computer. The high voltage of the equipment and interface lines transmitted to the human body causes electric shock, and the electrical isolation of the interface line becomes one of the important protective measures.
7>.Full speed devices: USB flash disk,Digital camera,Card reader,Mobile hard disk,U shield,USB HUB, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, J-Link, FET430UIF, PICKIT2, XDS100, LPC-Link, ICD2, USB to TTL module (Such as FT232, CP2102 ,PL2303,CH341)
8>.Low speed devices: Keyboard, Mouse,USBAPS, USBHID, USBCDC
9>.Unsupported devices:USB wireless card, Some USB3.0 USB flash disk
