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 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 the computer and personal safety. 2. Noise sensitive area Everyone knows that computers are a big source of noise. In the noise sensitive field, isolate the USB interface through this device. Such as high-precision USB data acquisition system, HIFI . 3. USB debugging device For example, various USB interface JTAG/SWD emulators, ISP/ASP/IAP/ 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. Colour: Black material: plastic 5. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera. Tested supported devices: Full speed equipment: USB flash drive, digital camera, card reader, mobile hard disk, U shield, USB hub, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, , FET430UIF, PICKIT2, XDS100, LPC-Link, ICD2, USB to serial port (FT232, CP2102, PL2303, CH341 chips). Tested unsupported devices USB wireless network card, some USB3.0 USB flash drive. Precautions: The onboard output power of this product is Jinsheng B0505S power 1W. When your USB device's working current is >180mA, you can use USB double-head cable to supply power. This product supports full speed devices, but does not support pure high speed devices (USB2.0). Most USB devices are backward compatible and can be used. Compatible with USB2.0 ADUM3160 isolation voltage: 2500V Power module isolation voltage: 1500V Support USB full speed 12Mbps does not support pure high speed equipment Support USB control transfer, batch transfer, interrupt transfer, sync/isochronous transfer Power supply: taken from the computer host USB port Free drive, more convenient to use Operating environment: -40 C to 85 C4 Package Contents: 1 * ADuM3160 isolator Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
