Zusammenfassung: | A charging system includes first and second ports each supported by a single power source configured to support a plurality of universal serial bus (USB) power transfer (PD) power levels. A controller is configured to, in operation, provide a negotiated PD power level from the single power source to the first port when only a single first device is connected to the charging system via the first port. The controller is further configured to, in operation, reduce power available by the first and second ports from the single power source to a predetermined level when a second device is connected to the charging system via the second port such that the first and second devices are both connected to the charging system.
一种充电系统包括均由一单个功率源支持的第一、第二端口,所述单个功率源配置成支持多个通用串行总线(USB)功率传输(PD)功率等级。一控制器配置成:在操作中,当仅一单个第一设备经由所述第一端口连接于所述充电系统时,将一协商的PD功率等级从所述单个功率源提供给所述第一端口。所述控制器还配置成:在操作中,当一第二设备经由所述第二端口连接于所述充电系统从而所述第一、第二设备均连接于所述充电系统时,将所述第一、第二端口从所述单个功率源可获得的功率减小至一预先设定的等级。 |
