1pcs 12Mbps USB Isolator Magnetic Coupling Isolation ADUM3160 USB

The product adopts the proprietary icoupler of ADI company ® Technology, is the industry's first single package USB isolation solution. Compatible with USB 2.0, it provides fully isolated 12 Mbps data rate, isolated 2500V voltage, no external power supply and no driver. The timing, amplitude, direction, rate and protocol of USB signal are extremely complex, so the magnetic isolation of USB signal is also a very complex technology. This paragraph basically represents the highest level in the isolation field.

Technical indicators:

■ compatible with USB2.0

■ isolation voltage of power module: 1500V

■ support USB full speed 12mbps, not pure high-speed devices

■ support USB control transmission, batch transmission, interrupt transmission, synchronization / isochronous transmission

■ power supply: from the USB port of the computer host

■ drive free, easy to use

■ service environment: - 40 ℃ to 85 ℃

Why isolate the USB interface?

USB interface has been one of the most commonly used interfaces for electronic engineers and employees in their daily work and life. With the increasing competition in the computer industry, the price of products is getting lower and lower,

Force most businesses to simplify the interface protection part of the computer motherboard, and save if possible. USB interface is not only often in contact with the human body and the outside, but also for many times

External equipment power supply. These many current situations lead to the early strike of USB interface of many computers. Even the motherboard is damaged.

This product is suitable for the following users:

1. Working environment with strong current and interference

Some circuits contain strong current and strong interference (such as high voltage, frequency converter, motor drive, etc.) environment,

When it comes to the connection with the computer, it must be isolated to ensure the computer and personal safety.

2. Noise sensitive areas

As we all know, computer is a big noise source. In the noise sensitive field, we can isolate the USB interface through this device. Such as high-precision USB data acquisition system and hifi audio system.

3. USB debugging equipment

For example, JTAG / SWD emulators with various USB interfaces, ISP / ASP / IAP / ICP downloaders, etc. When you often fail to connect and simulation exceptions occur during debugging, you can use USB isolator to try to improve.

4. Various industrial control USB devices

In industrial environment, USB devices often crash, such as USB mouse, keyboard, USB to serial port and other communication devices. USB isolator can effectively reduce the crash and damage probability of these devices in industrial environment.

Sometimes it is necessary to extend the USB cable. The USB isolator can act as a very excellent USB repeater and isolate the ground pressure difference between upstream and downstream equipment.

5. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB drive, printer, digital camera, USB hub and 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, j-link, fet430uif, pickit2, xds100, LPC link, ICD2, USB to serial port (ft232, CP2102, PL2303, CH341 chip).

After testing, unsupported devices include USB wireless network cards and some USB 3.0 USB drives.

matters needing attention:

The on-board output power supply of this product, Jin Shengyang b0505s, has a power of 1W. When the working current of your USB device is > 180mA, you can use the USB double head cable for external power supply.

This product supports full speed equipment, but does not support pure high-speed equipment (USB2.0). Most USB devices are downward compatible and can be used.
