USB-ISO is a USB Full speed USB 2.0 compliant port isolator with a 1000V isolation voltage. This device is very useful as protects your PC computer USB host from overvoltages, ESD shock, and it provides a 1000VDC isolation. This way you can connect to your PC programmers and debuggers which work directly with targets at high voltages like 220V mains power supply etc. Even if your target is not connected to a high voltage, USB-ISO gives additional protection to your valuable computer, laptop etc. equipment.

  • USB isolation 1000VDC between USB host and USB device
  • Uses ADUM4160
  • Requires USB device that support USB 1.1 Full Speed mode (data rate up to 12 Mbps).
  • Fits USB Audio Class 1 standard (the maximum throughput is 12 Mbps and 24 bits / 96 KHz.)
  • Bidirectional communication
  • Short-circuit protection for xD+ and xD- lines
  • Class 3A contact ESD performance per ANSI/ESD STM5.1-2007
  • High common-mode transient immunity: >25 kV/µs
  • USB_DEVICE connector- which is USB-B type and have to be connected to the PC USB host.
  • USB_HOST connector which is USB-A type and have to be connected to the USB device like USB equipment, audio equippment, development board, programmer, debugger etc
  • DC-DC converter supplies isolated voltage to the USB_HOST from the USB_DEVICE if no external power supply is present
  • Power jack for external power supply +8-15VDC, note the data lines are alway isolated but the power supply lines from the external power supply are not isolated from the USB_HOST connector (the personal computer is always protected; the power supply and the device connected to the USB_HOST might influnce each other in case of fault)
  • Dimensions (41.5 x 36.5) mm ~ (1.63 x 1.44)"
