Abstract
Exemplary power supply systems according to the present invention include circuitry that is configured to provide DC power and configured to receive a input signal that originates from a portable electronic device (the “PED”) and to provide a output signal to be sent to the PED. Such circuitry is configured to be coupled to the PED via a connector having a first, second, third, and fourth conductor. Such a connector is configured to be detachably mated with a power input interface of the PED to transfer the DC power to the PED, a ground reference to the PED, the input signal from the PED to the circuitry, and, in coordination with the input signal, the output signal from the circuitry to the PED, which is usable by the PED in connection with control of charging a battery of the PED based on the DC power provided by the circuitry.

A portable electronic device comprising:
- a rechargeable battery;
- power circuitry configured to receive direct current and to charge the rechargeable battery;
- and
- data circuitry configured to provide a first signal to a power supply and to receive a second signal from the power supply, the data circuitry and the power circuitry configured to be coupled via a connector to the power supply, the connector comprising a first conductor, a second conductor, a third conductor, and a fourth conductor, the connector configured to be detachably mated with an interface of the power supply to:
- transfer, via the first conductor, the direct current from the power supply,
- provide, via the second conductor, a ground reference from the power supply,
- communicate, via the third conductor, the first signal from the data circuitry to the power supply, and
- communicate, via the fourth conductor, the second signal from the power supply to the data circuitry;
- wherein the second signal has a parameter level that is usable by the data circuitry in connection with control of charging the rechargeable battery based on the direct current received by the power circuitry.
