Texas Instruments bq51003 无线接收器 Qi
德州仪器 bq51003 无线接收器 Qi 是高级的集成接收器 IC，被设计用于便携应用中的无线功率传输。此器件不但提供交流/直流电源转换，同时还集成符合 Qi v1.1 通信协议标准的数字控制功能。bq51003 可与 bq500210 发送器控制器组合，为无线供电解决方案提供完全无接触的电能传输系统。利用 近场感应电源传输，嵌入在便携式设备中的接收器线圈可通过相互耦合的电感器接受从发送器发出的电源。来自接收器线圈的交流信号在经过整流和调节之后，可用作系统关闭电子产品 (down-system electronics) 的电源。从二级到发射器建立了全局反馈，以便通过反向散射调制来稳定功率传输过程。这种反馈通过使用 Qi v1.1 通信 协议建立， 支持功率达 2.5W 的应用。
