Detection Switch 20-Pin UMLP EP T/R

The FSA9280A is a high-performance multimedia switch featuring automatic switching and accessory detection for the USB port. This switch allows sharing of a common USB port to pass audio, USB data / charging, as well as factory programmability. In addition, the FSA9280A integrates detection of accessories; such as headphones, headsets (MIC / button), car chargers, USB chargers, and UART data cables; with the ability to use a common USB connector. The FSA9280A can be programmed for manual or automatic switching of data paths based on accessory detected. FSA9280A includes an integrated 28V over-voltage and 1.5A over-current protected FET.
