Abstract: The present disclosure relates to a system and method to enable power negotiations between a Quick Charge (QC) power source with no USB power delivery (USBPD) support and a USBPD device. The proposed method identifies the support of USBPD and QC in the devices; determines the possibility of direct communication between the devices over either the D+/D?lines or the CC lines, initiates the power negotiations between USBPD device and QC power source either by translating the USBPD messages on CC line to QC signalling on the D+/D?lines and vice versa, or by handling the USBPD messages independently or combination of both; enable the fast charging of USBPD device till the maximum capacity of QC power source complying with USBPD and QC specifications.
