"TPS65982是TI公司的一款集成USB Type-C接口与USB Power Delivery (PD)控制器、电源开关及高速多路复用器的芯片。"
TI的TPS65982是一款针对USB PD规范设计的集成电路，它集成了多种功能于一身，以适应现代高速数据传输和电源管理的需求。该器件的主要特性包括：
1. **USB Power Delivery (PD) 控制器**：TPS65982能够处理USB Type-C连接器的插拔和方向检测，支持USB PD协议，能够在Host（提供者）、Device（消费者）以及Consumer-Provider（双向）模式下配置。
2. **双相标记编码/解码（BMC）**：采用BMC物理层协议，确保在CC线上进行稳定可靠的通信，这是USB PD协议的关键部分。
3. **物理层（PHY）协议**：TPS65982内部包含USB PD协议的物理层实现，负责数据传输的编码、解码和错误检测，确保USB PD通信的正确性。
4. **高速多路复用器**：该芯片内置高速切换开关，支持SuperSpeed Mux，可以处理高达SuperSpeed（5Gbps）的数据速率，同时具备3A电流能力，以满足高速数据传输需求。
5. **Type-C连接器管理**：TPS65982具备2个Type-C电缆检测和USB PD控制器，能够识别和管理D+/D-、SBU1/2、CC/VCONN、VBUS和GND等信号线，确保Type-C连接的兼容性和安全性。
6. **电源管理**：芯片能够根据PD协商结果控制VBUS的电压和电流，支持5V到20V的电压范围，最大5A的电流输出，同时具备VCONN电源管理功能，用于为Type-C连接器的辅助电源供电。
7. **外部FET控制**：通过外部FET的Sense和CTRL引脚，TPS65982可以灵活地控制外部电源开关，增强系统设计的灵活性。
8. **侧带数据接口**：除了USB数据传输外，还支持UART（通用异步收发传输器）和Side-Band数据，可用于扩展系统功能或与其他外设通信。
9. **2个Type-C电缆检测**：TPS65982能检测连接的Type-C电缆类型，如CC1/2引脚的状态，确保设备间通信的正确性。
该器件适用于需要USB Type-C接口和USB PD功能的设备，例如智能手机、平板电脑、笔记本电脑、充电器和其他便携式电子设备。配合TI提供的技术文档、工具软件和社区支持，开发者可以轻松地将TPS65982集成到他们的设计中，实现高效、安全的USB Type-C和USB PD解决方案。
