摘要： Handshaking circuits are provided in a communications cable and in a device operable to be mated with the communications cable. Before a device can utilize the power supply signal of such a communications channel, the two handshaking circuits must sufficiently identify one another over a power supply signal with a decreased voltage. The decreased voltage allows for a cable plug to be provided with a safe, protected power that cannot cause harm to a human. The decreased voltage also reduces the chance that a device can receive a primary power supply signal from the cable before the device sufficiently identifies itself. Accordingly, a laptop may be connected to a portable music player, but the voltage of the power supply signal provided by the laptop to the cable may be decreased on-cable until the handshaking circuit of the portable music player sufficiently performs a handshaking operation with a on-cable handshaking circuit.

摘要： This is generally directed to providing protection circuitry to selectively handle power-providing cables and headset cables that can couple to the same port of an electronic device. In some embodiments, the device can include a Headset Rx chip to communicate with the headset cable and a Power Rx chip to communicate with the power-providing cable. As the Headset Rx chip and the Power Rx chip can be coupled to the same contact of the device's port, these chips may prevent one another from operating correctly or may damage one another. Accordingly, in some embodiments, it can be determined whether a headset cable or a power-providing cable is coupled to the device. When a headset cable is coupled to the device, the protection circuitry can disconnect the Power Rx chip. Similarly, when a power-providing cable is coupled to the device, the protection circuitry can disconnect the Headset Rx chip.

摘要： A portable power source is configured for use with an electronic device. The portable power source cooperates and communicates with the electronic device via a peripheral bus to which the electronic device is attachable. The portable power source includes circuitry to process a power request signal from the electronic device to determine whether a device connected to a bus interface of the portable power source is requesting power from the portable power source.
