In an example embodiment, an apparatus comprises a controller coupled to a Universal Serial Bus (USB) port that is configured as a dedicated charging port (DCP). The controller is configured to detect whether a battery-charging (BC) compliant device or a BC non-compliant device is attached to the USB port. When a BC compliant device is detected, the controller controls the charging of the BC compliant device (e.g., by providing a maximum of 1.5 A of charging current). When a BC non-compliant device is detected, the controller controls the charging of the BC non-compliant device by providing a higher (e.g., up to 2.4 A) charging current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-standard compliant USB battery charging scheme with detection of host disconnection in ACA-DOCK mode","description":"Techniques for controlling the charging of portable devices are described herein.
