Is Now Part of 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 Semiconductors 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.

This configuration enables audio and USB data to share a common Low Power Consumption connector port. The architecture is designed to allow Packaged in Pb-free 10-pin MSOP and audio signals to swing below ground. This means a common 10-Lead MicroPak (1.6 x 2.1mm) USB and headphone jack can be used for personal media players and similar portable peripheral devices. Power-off Protection on Common D+/R, D-/L Ports Since USB2.0 is an industry standard for shared data- Automatically Detects V for Switch Path BUS path in portable devices, the FSA201 also incorporates Selection a V detection capability. The FSA201 includes a BUS power-off feature to minimize current consumption when Applications V is not present. This power-off circuitry is available BUS for the common D+/R, D-/L ports only. Typical Cell Phone, PDA, Digital Camera, and Notebook applications involve switching in portables and LCD Monitor, TV, and Set-Top Box consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers.
