Description
The FSA9485 is a high-performance multimedia
switch featuring automatic switching and accessory
detection for the USB port. The FSA9485 allows the
sharing of a common USB port to pass audio, video,
USB data / charging / On-The-Go (OTG), as well as
factory programmability.
In addition, the FSA9485 integrates detection for
accessories such as headphones, headsets (MIC /
Button), CEA-936-A Car Kit, USB chargers, and UART
data cables to use a common USB connector. The
FSA9485 can be programmed for manual switching or
automatic switching of data paths based on the
accessory detected.
With integrated 28V over-voltage protection and 1.5A
over-current protected FET, the FSA9485 integrates
common USB protection devices for V_BUS.
