1.4.4 Charging Downstream Port CDP是啥呢?其实它就是在PC或者HUB上的一个USB口,但是这个USB口比较特殊,可以提供1.5A~5A的大电流充电,一般都会有一个小闪电的标志在USB口旁边。 没连通外设时,当CDP检测到D+线上的电压VDAT_REF(Data Detect Voltage 0.25V~0.4V)< VDP < VLGC(Logic Threshold 0.8V~2V)后...
打开VDP_SRC (D+ Source Voltage 0.5~0.7v)and IDM_SINK(D- Sink Current 25~175 μA).D+和D-通过RDCP_DAT(Dedicated Charging Port resistance across D+/- max=200Ω)短接,PD检测D-的电压是否达到VDP_SRC(D+ Source Voltage 0.5~0.7v).PD在D-上的电压比较器比较D-电压和VDAT_REF(Data Detect Volt...
CDP(Charging Downstream Port 充電下接埠):具有更強充電能力的 USB Port。它具有 USB 資料傳輸,且能供給 BC1.2 可攜式裝置最大電流為 1.5 A。 DCP(Dedicated Charging Port 專用充電埠):是沒有 USB 資料傳輸功能的 CDP,它可以提供給 BC1.2 可攜式裝置 4.75V~5.5V 的電壓及 1.5A 的充電電流。DCP 會將其...
