一种Type-C接口保护电路及方法、移动终端
摘要：
本发明实施例提供了一种Type‑C接口保护电路及方法、移动终端，所述Type‑C接口具有CC1引脚和CC2引脚，所述电路包括：检测电压模块，用于检测输入至控制器的模数转换器ADC的电压值；控制器，用于根据所述模数转换器ADC的电压值生成上下电指令；CC逻辑处理器，用于根据所述上下电指令给所述CC1引脚或者CC2引脚上电或者下电。本发明实施例可以解决目前CC1或CC2引脚带电会加速CC1或CC2引脚化学腐蚀，影响设备插入检测，导致误判问题。
摘要（英）：

The embodiment of the invention provides a Type-C interface protection circuit and method, and a mobile terminal. The Type-C interface is provided with a CC1 (Configuration Channel) pin and a CC2 pin.The circuit comprises a voltage detection module, a controller and a CC logic processor, wherein the voltage detection module is used for detecting a voltage value which is input to the ADC (Analog to Digital Converter) of the controller; the controller is used for generating a power on and off instruction according to the voltage value of the ADC; and the CC logic controller is used for controlling the CC1 pin or the CC2 pin to be powered on or off according to the power on and off instruction. By use of the embodiment of the invention, the problems that equipment insertion detection is affected and misjudgment is caused since CC1 or CC2 pin chemical corrosion is accelerated because the existing CC1 or CC2 pin is electrified can be solved.
