Working Principles

FSUSB40UMX operates based on a selection control signal (SEL) received from the system. When the SEL signal is high, the switch connects the D+ and D- lines of the USB source to the downstream device. Conversely, when the SEL signal is low, the switch disconnects the D+ and D- lines, effectively isolating the downstream device from the USB source.
