Abstract
An electronic device is provided that may include an input port to couple to an external device, and a universal power interface to determine a type of the external device connected to the input port based at least on a voltage of a voltage supply line. The universal power interface may provide a power delivery path based on the determined type of the external device.
Claims12
An electronic device comprising:
- an input port to couple to an external device;
- and
- a universal power interface that includes a plurality of switches, the universal power interface to:
- determine a type of the external device coupled to the input port based at least on a voltage on a voltage supply line,
- provide a power delivery path based on the determined type of the external device, wherein to provide the power delivery path includes:
- provide power from a platform of the electronic device to the external device coupled to the input port, based on an operation of a first one of the switches, and
- provide steady power from the external device to the platform of the electronic device, based on an operation of a second one of the switches.

An electronic device comprising:
- a load;
- an input port to couple to an external device;
- and
- a universal power interface to alter a power delivery path based at least in part on a voltage on a voltage supply line between the input port and the load, wherein the universal power interface includes a plurality of switches,
- the universal power interface to provide power from the load of the electronic device to the external device coupled to the input port, based on an operation of a first one of the switches;
- and
- the universal power interface to provide steady power from the external device to the load of the electronic device, based on an operation of a second one of the switches.
4 more elements
A method of using an electronic device comprising:
- receiving at least two voltages from a voltage supply line between an external device and a host platform;
- determining a type of the external device based on the received voltages;
- and
- changing a power delivery path between the external device and the host platform based on the determined type of the external device,
- wherein changing the power delivery path includes operating a first switch to provide power from the host platform to the external device, and
- wherein changing the power path delivery further includes operating a second switch to provide steady power to the host platform of the electronic device.
