USB to USB Power Protection USB Digital Signal Noise Audio Isolation ADUM3160 USB Isolator USB Ground Loop Isolator
Product Description
The USB interface is already one of the most commonly used interfaces for electronic engineers and practitioners in their daily work and life. And as the competition in the computer industry is getting bigger and bigger, the price of products is getting lower and lower, forcing most businesses to simplify the interface protection part of the computer motherboard if they can, and save if they can. The USB interface is not only often in contact with the human body and the outside, but also provides power for external devices in many cases. These many status quo have caused the USB interface of many computers to go on strike in advance. Even the motherboard is damaged.

Application
1. Working environment with strong electricity and strong interference Part of the circuit contains strong electricity and strong interference (such as high voltage, frequency converter, motor drive, etc.) environment. When it involves connection with a computer, it must be isolated to ensure the safety of the computer and personal safety. 2. Noise-sensitive areas As we all know, the computer is a big noise source. In the noise-sensitive field, we can use this device to isolate the USB interface for communication. Such as high-precision USB data acquisition system, HIFI audio system. 3. USB debugging device Such as various USB interface JTAG/SWD emulators, ISP/ASP/IAP/ICP downloaders, etc. When you often fail to connect or emulate abnormalities during debugging, you can use a USB isolator to try to improve. 4. Various industrial control USB devices In an industrial environment, USB devices often crash, such as USB mice, keyboards, USB-to-serial ports and other communication devices. USB isolators can effectively reduce the chances of crashes and damage to these devices in industrial environments. Sometimes it is necessary to extend the USB cable, the USB isolator can act as a very good USB repeater, and can also isolate the ground pressure difference between the 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. Tested supported devices: Full speed device: U disk, 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). Tested unsupported devices: USB wireless network card, some USB3.0 flash drives.
Remarks
The onboard output power of this product is 1W. When the working current of your USB device is >180mA, you can use the USB double-headed cable to supply power.
