  • Dynamic sharing of power among USB type-c power delivery (USB-C/PD) ports
    Patent number: 11061457
    Abstract: Technology to dynamically share system power among charging ports of a multiport power delivery (PD) system is described. In one embodiment, a multiport PD system includes a master controller associated with a master port, and one or more slave controllers associated with one or more slave ports. The master controller determines a port connection status of a set of multiple ports. The port connection status indicates that multiple devices are connected. The master controller determines a power requirement of each of the devices. The master controller dynamically allocates a system power between each of the ports, independent of a connection sequence of the devices.
