Embodiment Construction

[0019] Embodiments of the invention relate to electronic devices with connector ports. Electronic devices such as laptop computers, tablet computing devices, cellular telephones, music players, or other portable electronic devices may contain connector ports for communicating with other electronic devices. A given connector port (sometimes referred to herein as a female connector) accepts a connector plug (sometimes referred to herein as a male connector) with a corresponding connector cable that A given connector port is electrically coupled to a connector port of another electronic device. Each port may contain conductive paths (eg, metal traces, conductive pins or contacts) through which data signals or power signals may be transmitted between the port of the connector plug and the corresponding conductive path. For example, a tablet computing device may include a connector port that is used to communicate with a speaker dock (eg, by providing audio signals to the speaker ...

Abstract

An electronic device may include a connector port that accommodates reversible connector plugs. The connector port may include protection circuitry that protects other components in the electronic device from undesired power supply voltages. The protection circuitry may form a first branch and a second branch opposite to the first branch. The protection circuitry may receive control signals from power polarity detection circuitry. The power polarity detection circuitry may detect the presence of power supply voltages at the first branch and the second branch. In response to detecting the presence of a power supply voltage at a given branch, the power polarity detection circuitry may disable a power supply signal path through the opposite branch and enable a power supply signal path through the given branch.

Description

[0001] This application claims priority to US Patent Application No. 13 / 191,275, filed July 26, 2011, which is incorporated herein by reference in its entirety. technical field [0002] The present application relates generally to electronic devices with connector ports, and more particularly, to electronic devices with reversible connector ports with protection circuits. Background technique [0003] Handheld electronic devices and other portable electronic devices are becoming more and more popular. Examples of handheld devices include handheld computers, tablet computers, media players, cellular phones, and hybrid devices that include the functionality of multiple devices of this type. [0004] Electronic devices, such as handheld electronic devices, often include connector ports. For example, some cellular telephones include 30-pin connector ports. Connector ports such as these can be used as input / output data ports and can accept connector plugs (sometimes referred to...
