Description

The FSA9285A is a high-performance multimedia switch

featuring automatic switching and accessory detection for a USB

port. The FSA9285A allows sharing of a common USB port to

pass audio and USB data while simultaneously charging.

In addition, the FSA9285A integrates detection of accessories

such as headphones, headsets Mobile Computing Promotion

Consortium (MCPC) with MIC and Send/End, car chargers,

USB chargers, USB On-The-Go (OTG), and Accessory

Charging Adapters (ACA) to use a common USB connector.

The FSA9285A can be programmed for manual or automatic

switching of USB data paths based on the accessory detected.

With an integrated 14 V over-voltage and 1.45 A over-current

protected FET, the FSA9285A integrates common USB

protection functions for VBUS.

Applications

 Mobile Phones, Portable Media Players
