Abstract

一种Type C USB接口的控制方法、应用与电子设备。将Type C USB接口(J1)的屏蔽壳与电子设备的地断开连接，获取屏蔽壳的电平(V12)，并根据所获取的电平(V12)确定是否有外部设备插入或拔出该Type C USB接口(J1)；当确定有外部设备插入电子设备的Type C USB接口(J1)，向Type C USB接口(J1)的CC管脚输出信号；当确定外部设备从电子设备的Type C USB接口(J1)拔出，或没有外部设备与Type C USB接口(J1)连接，停止向Type C USB接口(J1)的CC管脚输出信号。通过上述的控制方法可改善终端电量消耗以及安全隐患的问题。
