图2显示,如果使用5V降压转换器,设计工程师只能输出一个固定5V电压,这与很多USB-C应用要求的可调5V-20V OTG输出电压不匹配。 图2. 现有电池充电器架构 - 单一降压-升压充电器+复杂的外部逻辑电路 USB-Type-C 1:USB-C端口1 5V OTG only:仅5V OTG Charging battery & Support system:充电电池和支持系统 Externa...
To fix this, always use the charger and cable included with your PC and make sure you’re connecting your charger to the USB-C charging port on your PC. Also, try using a compressed air can to clean your PC’s USB-C port. In this case, it is best to use the charger and cable ...

使用E-mark第三原则:这两个原则是用来判断设备上是否需要TYPE-C芯片,另外一点很受关注的C-C传输线上是否需要用到E-MARKER芯片,这个判断标准是,使用过程中,电流是否会超过3A?如果不超过,则可以不需要, A to C, B to C的线,则看是否需要实现Battery Charging协议,如果要实现,则可以使用LDR6013,带来的好处是,...
Power Role定义了供电的角色。根据USB PORT的供电情况来划分,Source是供电方,Sink则是受电方。Source Only表示只能作为供电方,Sink Only则只能作为受电方。默认情况下,设备为Source模式,但可以通过PD SWAP协议切换为Sink模式。 通讯信号内容: 源模式阶段:
最近笔记本出现问题,关机后自动启动,我先是试了下B站上的一些办法,关闭一些系统选项后无果。在国外论坛上搜罗了一下,发现也有人是我这样的问题,就是设备管理器→通用串行总线控制器→NVIDIA USB Type-C Port Policy Controller,每次都是这个会唤醒我的笔记本电脑,但是哪怕是在设备管理中,将允许此设备唤醒计算机取消...
My 2 week old Laptop will not connect to my Samsung Galaxy S8 phone for data transfer, nor for charging, using the USB-C port. The other three USB-A ports work fine, for both charging and for data transfer. I have tried two different S8 phones, ...
