FSA4480

USB Type-C Analog Audio
Switch with Protection
Function

FSA4480 is a high performance USB Type−C port multimedia
switch which supports analog audio headsets. FSA4480 allows the
sharing of a common USB Type−C port to pass USB2.0 signal, analog
audio, sideband use wires and analog microphone signal. FSA4480
also supports high voltage on SBU port and USB port on USB Type−C
receptacle side.
