USB Isolator ADuM3160 with Galvanic Isolation

USB port isolator module based on the ADuM3160 chip, using Analog Devices' iCoupler technology. The device provides 2500 V galvanic isolation for data lines and 1500 V for power. It effectively protects computer USB ports from overvoltages, short circuits, and interference from connected external devices. The module is an excellent choice for use with popular platforms such as Arduino, ESP8266, ESP32, and Raspberry Pi.

Key Technical Features

• Isolation chip: ADI ADuM3160 (iCoupler technology)
• Transmission speed: USB 1.1 / 2.0 (Low Speed and Full Speed up to 12 Mb/s)
• Data line isolation voltage: 2500 V
• Converter isolation voltage: 1500 V (Mornsun B0505S chip used)
• Isolated side power supply: built-in 5V to 5V converter, 1 W power
• Maximum output current: up to 200 mA (recommended continuous load 180 mA)
• Supported transfers: control, bulk, interrupt, isochronous
• Connectors: USB-A plug - USB-A socket
• System compatibility: Windows, Linux, macOS (plug-and-play, no drivers required)

Example Applications

• Protecting computer ports during microcontroller programming and debugging (programmers J-Link, ST-Link, AVRISP, PICKIT)
• Hardware protection when working with USB-UART converters (FT232, CP2102, PL2303, CH341 chips)
• Galvanic isolation of measurement systems, oscilloscopes, and logic analyzers
• Eliminating ground loops in audio devices and converters
• Safe connection of USB hubs, card readers, and digital cameras
• Work in workshop environments exposed to electromagnetic interference

Benefits

• Effective hardware protection: galvanic separation protects computers from damage due to overvoltages.
• No installation required: the device works immediately after connection and does not require additional drivers.
• Convenient power supply: the module draws power from the USB host port, eliminating the need for external power supplies.
• Interference reduction: physical separation of circuits helps eliminate power supply noise.
• Wide compatibility: seamless operation with most operating systems and Full Speed devices.

Note: The isolator supports transmission speeds up to 12 Mb/s. It does not support devices requiring High Speed mode (480 Mb/s), such as fast storage drives or Wi-Fi network cards.
