TPS65986是一款独立式USB Type-C和USB供电(PD)控制器,可在USB Type-C连接器中提供电缆插入状态和方向检测。在电缆检测过程中,TPS65986会在CC线上使用USB PD协议进行相应传输。当完成电缆检测和USB PD协商后,TPS65986会使能相应的电源路径,并配置外部(任选)多路复用器的交替模式设置。
CC引脚上的混合信号前端可为Type-C电源提供默认值(900mA),1.5A或3A三种电流,检测电缆插入事件,确定USB Type-C电缆方向以及遵循指定的双相标记编码(BMC)和物理层(PHY)协议自主协商USB PD合约。
端口电源开关在5V电压下可为传统USB电源和Type-C USB电源提供高达3A的下行电流。当USB PD电源用作供电器件(主机),受电器件(设备)或供电 - 受电器件时,附加的双向开关路径可在最高20V的电压下为其提供高达3A的电流
此外,TPS65986也可用作上行数据端口(UFP),下行数据端口(DFP)或者双角色数据端口。端口数据终端可实现端口与顶部或底部D + /D-信号对之间的数据传输,并且具有一个USB 2.0低速端点。电源管理电路利用系统内部的3.3V电源供电,同时使用VBUS启动并针对电池电量耗尽或无电池情况进行供电协商。
