USB Hub with Integrated Power and Thermal Management

Abstract:

A universal serial bus (USB) dock includes USB ports, each configured to connect to a respective USB element. The USB dock includes a circuit communicatively coupled to the USB ports and configured to determine a first temperature measurement in the USB dock, determine a power demand for each USB element connected to the USB ports, determine an allocation of power for the USB elements, and, based on the first allocation of power, provide less than the power demand for one or more of the USB elements based upon a total power demand by the USB elements and the first temperature measurement.
