Description

General part information

FSA9285 Series

The FSA9285 is a high-performance multimedia switch featuring automatic switching and accessory detection for a USB port. The FSA9285 allows sharing of a common USB port to pass audio and USB data while simultaneously charging. In addition, the FSA9285 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 FSA9285 can be programmed for manual or automatic switching of USB data paths based on the accessory detected. With an integrated 28V over-voltage and 1.45A over-current protected FET, the FSA9285 integrates common USB protection functions for VBUS.For additional performance information, please contact analogswitch@ON Semiconductorsemi.com.
