This USB isolator is made for someone leads to burning the USB port of the computer device or the host device,and even burning the motherboard. Some electronic enthusiasts use the bare electronic device but may damaged the device accidently by some wrong operation. When you DIY a new circuit board, but there may be a short circuit or the current is too large, plugged into the computer for testing,causing the USB port to burn down or the motherboard is damaged. We have created a hardware device that can prevent this situation. Known as USB isolation.Its biggest feature is to prevent accidental surge attacks and prevent short circuits when you use USB properly. It is the protection of your computer, microcontroller, Raspberry Pi and other electronic devices! Protect your computer or the USB port of your development board without affecting your USB device use! When a short circuit condition occurs, a red light will be lit on the USB isolation device, which will remind you that the access device is short-circuited and will not cause damage to your computer. The USB Isolator is based on ADuM3160 component.Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics and is easily integrated with low and full speed USB-compatible peripheral devices. Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design;however, this presents particular challenges when isolation is required. Because the USB lines must switch between actively driving D+/D− and allowing external resistors to set the state of the bus,the ADuM3160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers.
