The uniqueness of Sonnet USB 3.2 products is each USB port has a USB power switch (MOSFET) that manages and monitors the current flow of the USB port. The USB switch limits the current draw when a new USB device is connected minimizing the voltage droop of the main USB 5V power rail, thereby protecting devices connected to other USB ports from going offline because of port power droop. The USB switch is also a very effective current limiter that does not degrade over trips the way a resettable poly-fuse would.
