FSA9280A

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.
