RT7211 是一款低静态电流 USB Type-C Power Delivery (PD) 控制器，专为灵活的 source 或 sink 应用而设计。内嵌 MCU 与双相标记编码 (BMC) 发送器可管理 PD 协议通信，而集成式 DAC 与 ADC 模块则提供精准的电压与电流调节。作为 source 控制器时，它适用于离线式 AC-DC 转换器，或在搭配外部降压或升降压控制器时，用于车载充电器等 DC-DC 转换器应用。作为 sink 控制器时，它提供简单且具成本效益的电力协商解决方案，并具备 I<sup>2</sup>C 接口与两个 GPIO，以提升灵活性并便于与外部 MCU 集成。建议结温范围为 −40°C 至 125°C，环境温度范围为 −40°C 至 105°C。
