A first device provides both power and data to a second device over a power line connection between the two devices. The first device includes a power line extending from a power supply, a ground line extending from a ground, a first impedance in the power line, and a second impedance in the ground line. A modulator comprised of a transistor and modulator impedance is between the first impedance and the second impedance, and a tank capacitor is between the power line and the ground line, outside the first impedance and second impedance. A comparator is coupled between the first and second impedance. A switch may be included to short out the first and second impedance, thereby enabling transmission of only power for period of time, and return to a mode of transmitting both data and power. The first device may also receive data from the second device over the power line connection.
A method for providing data over a power connection from a power source device to a mobile device, the method comprising:
A method for receiving data at a mobile device from a power source device over a power line between the power source device and the mobile device, the power line comprising a single electronic connection from the power source device to the mobile device, the method comprising:
A method for exchanging data between a mobile device and a power source device over a power line between the power source device and the mobile device, the power line comprising a single electronic connection from the power source device to the mobile device, the method comprising:
