    摘要： Methods, circuits, and apparatus to distribute power among devices in an electronic system where a device may receive power from more than one source, may have a bidirectional power connector, or both. One example may resolve conflicts when an electronic device receives power from more than one source. In this example, the device may determine which source may provide the most power, and may select to receive power from the power source that may deliver the most power. Other examples may have a preference to receive power from a particular source or via a specific connector. Other examples may switch from receiving power over a first connector to providing power over the first connector, while others may receive and provide power over different connectors at the same time. Another may be connected to a battery, and may draw power from the battery or not depending on the type of battery.

    摘要： The disclosed embodiments provide a system that manages power allocated through a set of bus interfaces on a computer system. During operation, the system obtains a first request for revocable current beyond a reserved current for a first bus interface from the set of bus interfaces, wherein the request is associated with a first device connected to the first bus interface. Next, the system allocates the revocable current to the first bus interface from an extra-current budget for the set of bus interfaces. Upon detecting a connection of a second device that requires non-revocable current over the extra-current budget to a second bus interface from the set of bus interfaces, the system transmits a first notification to the first device to relinquish the revocable current. Finally, the system allocates the non-revocable current to the second device from the relinquished revocable current.

    摘要： Interface circuits that may utilize a limited number of pins to detect a presence of an accessory, determine whether the accessory can provide or receive power, communicate with the accessory regarding at least that transfer of power, and transfer power accordingly. One example may provide detection circuitry for a host that may detect the presence of a pull-down resistor on a data pin of an accessory. The pull-down may indicate that a power consuming accessory has been connected. This example may detect the presence of power on a power pin. The presence of the power on the power pin may indicate that a power providing accessory has been connected.
