摘要： Universal Serial Bus (USB) cable type detection and control techniques are disclosed. In an exemplary aspect, a device connected to a cable detects whether the cable is a legacy cable (i.e., a Type-A to Type-C cable). If the cable is a legacy cable, the device determines an appropriate current to draw based on whether the cable is compliant with the USB Type-C specification or non-compliant. Additional exemplary aspects of the present disclosure determine whether a connector adaptor has been put on a legacy cable and determines an appropriate current to draw based on the capabilities of the legacy cable. Still further aspects of the present disclosure evaluate not only the cable to see if the cable limits the current draw, but also evaluate a device at a distal end of the cable to verify if and how current may be drawn by such remote device from a mobile terminal.

摘要： Over-voltage protection systems and methods are disclosed. In one aspect, a biasing circuit is added to a pre-existing clamp required by the Universal Serial Bus (USB) Type-C specification at a configuration control (CC) pin. The biasing circuit turns the pre-existing clamp into an adjustable clamp that dynamically adjusts to over-voltage conditions. In an exemplary aspect, the biasing circuit may include a biasing field effect transistor (FET) and a pair of switches that selectively couple the pre-existing clamp and the biasing FET to fixed voltages such that the CC pin is maintained at an acceptable voltage. In another exemplary aspect, the biasing circuit may omit the biasing FET and rely on two switches that selectively couple the pre-existing clamp to fixed voltages such that the CC pin is maintained at an acceptable voltage.
摘要翻译：公开了过压保护系统和方法。在一个方面，在配置控制（CC）引脚处将偏置电路添加到通用串行总线（USB）C型规范所要求的预先存在的钳位。偏置电路将预先存在的钳位转换为可调节钳位，可动态调整过压状态。在示例性方面中，偏置电路可以包括偏置场效应晶体管（FET）和一对开关，其选择性地将预先存在的钳位和偏置FET耦合到固定电压，使得CC引脚保持在可接受的电压。在另一示例性方面中，偏置电路可省略偏置FET并依赖于两个开关，这两个开关将预先存在的钳位选择性地耦合到固定电压，使得CC管脚保持在可接受的电压。
