Abstract: An electronic system can include a charged system and a charging system. The charged system can include a charger and a battery configured to be charged thereby. The charger may be configured to receive power from a charging system that includes a power converter configured to supply power to the charger and a controller configured to control the power converter. The controller may be configured to receive feedback information from the charged system, including one or more voltages. The controller may be further configured to determine an output voltage compensation value for the power converter as a function of the feedback information and to set an output voltage of the power converter as a function of the compensation value. The compensation value and output voltage may be selected to maintain a preselected headroom between a battery charging target voltage of the charger and a voltage supplied to the charger.

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 translation: 简化接口，用于充电和附件与扩展坞之间的通信。 一个示例可以提供用于在附件和坞站之间进行充电和通信的接口，其中在相同的引脚上提供数据和充电电压。 附件可以通过接收充电电压来确定其处于电源对接站。 附件可以通过向未供电的对接站提供电压来确定其处于无动力对接站，其中无电对准站使用电压为振荡器供电。 振荡器信号可以被附件接收，附件可以使用信号的存在来确定它处于未供电的坞站中。
