Classification: CPC G | IPC G

Claim 9:
10. A method of dynamic power sharing using a dual universal serial bus (USB) Type C and PD receptacle, comprising:
initializing power for the dual USB Type C and PD receptacle that comprises a plurality of USB ports including a USB Type C power delivery (PD) port and a USB Type C port, the USB ports being couplable to respective devices for charging;
determining, by a controller of the receptacle, whether one or more USB ports are coupled to the respective devices for charging;
managing, by the controller, power negotiation and dynamic power sharing between the USB Type C PD port and the USB Type C port based on the determination; and
supplying power to at least one of the USB ports based on the determination, the power comprising high power supplied directly from an alternating current (AC) to direct current (DC) converter to a first respective device coupled to the USB Type C PD port and low power supplied directly from a DC/DC converter to a second respective device coupled to the USB Type C port, the DC/DC converter structured to receive the high power from the AC/DC converter and reduce to the low power,
wherein the controller comprises a first controller that is coupled to the USB Type C PD port and a first switch external to the first controller and a second controller that is coupled to the USB Type C port and a second switch external to the second controller;
wherein in response to a determination that both the USB Type C PD port and the USB Type C port are coupled to the respective devices, the managing power negotiation and dynamic power sharing comprises:
activating a dynamic power sharing logic;
turning on the USB Type C PD port by the first switch and the USB Type C port by the second switch; and
advertising, by the USB Type C PD port, a first power profile and advertising, by the USB Type C port, a second power profile, the first power profile comprising a first power rating and a first voltage and current rating of the USB Type C PD port and the second power profile comprising a second power rating and a second voltage and current rating of the USB type C port, the first power rating being a difference between a total power capacity of the receptacle and the second power rating.
