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. Switch Type Switch Mechanism 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 VBUS.
