Description
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.
