ADUM3160 USB to USB Isolator, USB 2.0 Full Speed 12Mbps, Host-Powered, Driver-Free

Using ADI's proprietary iCoupler® technology, the product is the industry's first single-encapsulated USB isolation solution. Compatible with USB 2.0, provide fully isolated 12 Mbps data rate, isolated 2500V voltage, no external power supply, no driver. USB signal timing, amplitude, direction, rate, protocol are extremely complex, so the implementation of USB signal magnetic isolation is also very complex technology, this section basically represents the highest level of isolation in the field. Technical indicators: S compatible with USB2.0 ■ ADUM3160 isolation voltage: 2500V ■ Isolation voltage of power module: 1500V ■ Support USB full speed 12Mbps does not support pure high speed devices ■ Support USB control transmission, batch transmission, interrupt transmission, synchronous/isochronous transmission ■ Power supply: from the computer host USB port ■ Free drive, more convenient to use ■ Operating environment: -40℃ to 85℃ Why quarantine USB ports? USB interface has been one of the most commonly used interfaces in the daily work and life of electronic engineers and practitioners. And as the computer industry became more and more competitive, and products became cheaper and cheaper, Forcing most businesses to computer motherboard interface protection part can be simplified to simplify, can save the province. USB interface is not only often with the human body, external contact, and many times it is also Power supplied by external equipment. All this has led to an early shutdown of the USB ports on many computers. Even the motherboard was damaged. This product is suitable for the following users: 1. The working environment with strong electricity and strong interference Part of the circuit contains strong current, strong interference (such as high voltage, frequency converter, motor drive, etc.) environment, When it comes to the occasion of connecting with the computer, isolation must be carried out to ensure the computer and personal safety. 2. Noise sensitive area As we all know, computers are a big source of noise. In the noise sensitive area, we can communicate and isolate the USB interface through this device. Such as high-precision USB data acquisition system, HIFI sound system. 3. USB debugging equipment Such as a variety of USB interface JTAG/SWD emulator, ISP/ASP/IAP/ICP downloader. When you can not connect frequently in the debugging process, simulation exception, you can use the USB isolator to try to improve. 4. All kinds of industrial USB devices In industrial environment, USB devices often crash, such as USB mouse, keyboard, USB to serial port and other communication devices. USB isolators can effectively reduce the chance of these devices crashing and damaging in industrial environments. Sometimes it is necessary to extend the USB cable, and the USB isolator can act as an excellent USB repeater, as well as isolating the ground pressure 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,USB camera. Supported equipment after testing: Full speed equipment: USB drive, 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 serial port (F T232, CP2102, PL2303, CH341 chips). After testing does not support the device USB wireless network card, part of the USB3.0 USB flash drive. Note: The on-board output power of this product is Jinshengyang B0505S with 1W power. When the working current of your USB device is >180mA, you can use the USB double-ended cable to supply power. This product supports full speed devices, but not pure high speed devices (USB2.0). Most USB devices can be used with downward compatibility.
