FSA4485 Overview
The FSA4485 is a high performance USB Type−C port multimedia switch to supports analog audio headsets. The FSA4485 allows sharing of the USB Type−C port to pass USB2.0 signals, analog audio, sideband use signals, and analog microphone signal. For enhanced audio performance the FSA4485 incorporates MOSFET gate drivers to support low resistance external analog ground switches.
