Abstract: An electronic device may receive or provide power using bidirectional wired and wireless power converters. A bypass path may be included to bypass the battery charger and to allow direct power transfers from a connector of the electronic device to the wireless power converter or from the wireless power converter to the connector of the electronic device. Current limiting and regulation circuitry may also be included.

Abstract: A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.
Abstract translation: 测量作为系统的外部连接器的多个引脚之一的第一引脚的电压，而除了通过第一电阻被拉到地之外，第一引脚是未驱动的，并且 外部连接器的第二引脚被用作系统的电源导轨。 将测量的电压与短路阈值进行比较，并且响应于超过该阈值，第二引脚上的电源电压降低。 在这样的实施例中，不需要将测试刺激施加到外部连接器的任何引脚。 其他实施例也被描述和要求保护。
