To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Description
FSA4476 is a high performance USB Type-C port multimedia switch which supports analog audio headsets. FSA4476 allows the sharing of a common USB Type-C port to pass USB2.0 signal, analog audio, sideband use wires and analog microphone signal. FSA4476 also supports high voltage on CC port, SBU port and USB port on USB Type -C receptacle side. In addition, FSA4476 supports USB Type -C dead battery application and dual power supply with VBAT rail and VBUS rail.

Application Information
FSA44776 supports dead battery application. When power is not applied to FSA4476 and it is attached to a Source device, then the Source would pull up the CC line connected through the cable. FSA4476 in response would turn on the pull -down that will bring the CC voltage to a range that the Source can det ect an attach event and turn on VBUS. Headset detection FSA4476 integrates headset unplug detection function by detecting the CCx_H voltage. The headset detection is only active during audio switch on status (EN1=1). When headset is attached ( both CC1 _H and CC2_H are Low), the flag signal is sent low to host controller by INT1 (INT1= low) . Once either of CCx_H= High (CCx_H>1.5V), INT1 will be released to high by external pull up resistor.
