SYSTEMS AND METHODS FOR PORT MANAGEMENT
First Claim
1. A method of controlling power for a device, comprising:
- detecting insertion of a connector into a Universal Serial Bus (USB) Type-C receptacle;
determining if power is available through the USB Type-C receptacle or if power is being drawn through the USB Type-C receptacle;
negotiating power levels if power is available;
determining if other modes are supported through the USB Type-C receptacle; and
controlling such other modes if available.

Abstract
Systems and methods for port management are disclosed. In one aspect, the system may consolidate port management functions as well as power conversion, protection features, and signal conditioning circuitry into a single integrated circuit (IC) for a device without a battery. Further exemplary aspects allow for arbitration between ports to handle power supply versus power sink functions. Still further exemplary aspects provide an indication when a weak power source is coupled to the computing device to alert a user that the weak power source may not provide sufficient power for full operation. Such consolidated functionality allows a single form factor to be used for all ports whether the ports are used as a power port or an output port. Further, such consolidated functionality helps mitigate possible damage caused by improper activity.
