diymore USB Bộ Cách Ly, Tín Hiệu Kỹ Thuật Số An Toàn Cách Ly Dòng Bảo Vệ ADUM4160 Module Cách Ly

Description:
This product uses ADI's proprietary iCoupler® technology and is the industry's first single-package USB isolation solution. Compatible with USB 2.0, it provides complete isolation of 12 Mbps data rate, isolation of 5000V voltage, no external power supply, no driver. The timing, amplitude, direction, speed, and protocol of the USB signal are extremely complex, so the realization of the magnetic isolation of the USB signal is also a very complicated technology. This paragraph basically represents the highest level in the isolation field.

Why should I isolate the USB interface?
The USB interface is already one of the most commonly used interfaces for electronic engineers and practitioners in their daily work and life. With the increasing competition in the computer industry, product prices are getting lower and lower,
Forcing most businesses to simplify the interface protection part of the computer motherboard to simplify it, or to save it. The USB interface is not only in contact with the human body and the outside, but also in many cases
External device power supply. These many current conditions have led to an early strike on the USB interface of many computers. Even the motherboard is damaged.

This product is suitable for the following users:
1. Working environment with strong electricity and strong interference
Some circuits contain strong electricity and strong interference (such as high-voltage electricity, inverters, motor drives, etc.) environments,
When it comes to connecting with a computer, it must be isolated to ensure the computer and personal safety.
2. Noise sensitive areas
Everyone knows that computers are a big source of noise. In the noise-sensitive area, we can isolate the USB interface through this device. Such as high-precision USB data acquisition system, HIFI audio system.
3. USB debugging equipment
For example, JTAG/SWD simulators of various USB interfaces, ISP/ASP/IAP/ICP downloaders, etc. When you often fail to connect or simulate abnormalities during debugging, you can use a USB isolator to try to improve.
4. Various industrial USB devices
In an industrial environment, USB devices often crash, such as communication devices such as USB mice, keyboards, and USB to serial ports. The USB isolator can effectively reduce the crash and damage probability of these devices in an industrial environment.
Sometimes it is necessary to extend the USB cable. The USB isolator can act as an excellent USB repeater and can also isolate 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 (HUB), USB camera.
6. Medical equipment
The safety of the human body is the most important and primary consideration. However, some medical equipment is connected to the computer through a USB interface. In the process of human body data or treatment, it needs to have direct electrical contact with the human body.

To avoid electric shock caused by high voltage that may be conducted from the computer to the human body through equipment and interface lines, electrical isolation of interface lines is one of the important protective measures.

Tested and supported equipment:
Full speed equipment:
USB, digital camera, card reader, mobile hard disk, USB shield, USB hub, AVRJTAG, AVRISP, AVRISPMKII, S-Lab, JET51, J-Link, FET430UIF, PICKIT2, XDS100, LPC-Link, ICD2, USB transfer Serial port (FT232, CP2102, PL2303, CH341 chip).
USB wireless network cards and some USB3.0 flash drives that are not supported by the test.

Precautions:
The onboard output isolation power of this product is 0.75W-1W. When the working current of your USB device is >150mA, you can use an external power supply.
This product supports full-speed devices, but does not support pure high-speed devices (USB3.0). Most USB devices are backward compatible and can be used
