    Abstract: Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described. Upon detecting an input power signal from the charging source, an accessory may send an identification request to the host device and authenticate the host device based on the identification information received from the host device. Upon authenticating the host device, the accessory may enable a power path between the charging source and the host device to supply a charging current to charge the host device.

    Abstract: Simplified interfaces for charging and communication between accessories and docking stations. One example may provide an interface for charging and communication between an accessory and docking station where data and a charging voltage are provided over the same pins. An accessory may determine that it is in a powered docking station by receiving a charging voltage. The accessory may determine that it is in an unpowered docking station by providing a voltage to the unpowered docking station, where the unpowered docking station uses the voltage to power an oscillator. The oscillator signal may be received by the accessory, which may use the presence of the signal to determine that it is in an unpowered docking station.

    Abstract: Methods, systems, and apparatus for determining whether an accessory includes particular circuitry. A host device may measure a first voltage and a second voltage received from an accessory, where the voltages are provide through the accessory from a power source. Before measuring the second voltage, the host device may send an instruction to the accessory instructing the accessory to alter an impedance of the power path between the power source and the host device, and the host device may draw at least a threshold amount of current from the power source via the accessory. The host device may then determine whether the accessory includes particular circuitry based on the relationship between the first voltage and the second voltage.
