Last Updated: 
Aug 18, 2015

AN92554 introduces the basics of USB battery charging and describes standard and proprietary battery charger detection mechanisms supported by HX3 on its upstream and downstream ports. This application note also helps you to understand the HX3-specific features like Ghost Charge and ACA-Dock, and provides the guidelines to implement various battery charging features.




HX3 is a family of USB 3.0 hub controllers compliant with the USB 3.0 specification revision 1.0. HX3 supports SuperSpeed (SS), Hi-Speed (HS), Full-Speed (FS), and Low-Speed (LS) modes. In addition to implementing a USB 3.0 hub, the HX3 family includes advanced USB battery charging capabilities to meet the demand for battery charging over USB.
