Texas Instruments 德州仪器 TPS65982 USB Type-C & 供电 (PD) 控制器

德州仪器 TPS65982 USB Type-C & 供电 (PD) 控制器在 USB Type-C 连接器上提供电缆插头和方向检测。一旦检测到电缆，TPS65982 即使用 USB PD 协议在 CC 线上进行通信。在电缆检测和 USB PD 协商完成时，TPS65982 启用专有的电源路径，并针对内部和（可选）外部多路复用器配置交替模式设置。CC 引脚上的混合信号前端用于显示 Type-C 电源的默认值 500mA、1.5A 或 3A。它可以检测插头动作，并确定 USB Type-C 电缆方向。它还能通过遵守指定的双向标记编码方案（BMC）和物理层（PHY）协议，自动协商 USB PD 协议。
