| description | The invention provides a method and circuit for protecting a chip of electronic equipment and the electronic equipment, in the method, when it is recognized that a USB interface is in a quick charging scene, a circuit between a D + pin and a D-pin in the USB interface and an internal SOC is controlled to be open, and when it is recognized that the USB interface is in a data transmission or analog audio transmission scene, the circuit between the USB interface and the internal SOC is controlled to be open. And if so, controlling a circuit between a D + pin and a D-pin in the USB interface and the internal SOC to be communicated. Therefore, on the premise that the normal function of the USB interface is realized, the SOC in the USB interface circuit is protected from being damaged by the overelectric stress introduced by the D + pin and the D-pin.
本申请提供了一种保护电子设备芯片的方法、电路及电子设备，在该方法中，当识别到USB接口处于快速充电场景时，则控制USB接口中D+、D-管脚与内部的SOC之间的电路开路，当识别到USB接口处于数据传输或模拟音频传输场景时，则控制USB接口中D+、D-管脚与内部的SOC之间的电路联通。这样可以在保证USB接口实现正常功能的前提下，保护 |
