What does a USB isolator do?

The USB isolator can cut off the electrical connection between the two sides of the USB communication, and the power line and the signal line are not directly connected, and the power noise and ground line noise on the host side will not escape to the USB device. In industrial occasions, the side of USB devices is often exposed to high voltage and high noise environments, so as to prevent dangerous voltage and noise from interfering with the host.
