BQ51013B-Q1 器件是一款灵活的高级单芯片次级侧器件，适用于便携式应用中的无线电力传输，可提供高达 5W 功率。BQ51013B-Q1 器件在集成符合无线电源联盟 (WPC) Qi v1.2 通信协议所需的数字控制的同时，提供接收器 (RX) 交流/直流电源转换和稳压。BQ51013B-Q1 与 BQ50012A 初级侧控制器（或其他 Qi 发送器）相结合，可为无线电源解决方案实现一个完整的非接触式电力传输系统。使用 Qi v1.2 协议，在次级侧与初级侧之间建立全局反馈，从而控制电力传输过程。

BQ51013B-Q1 集成了一个低电阻同步整流器、低压降稳压器 (LDO)、数字控制以及精确的电压和电流环路，可确保高效率和低功率耗散。

The BQ51013B-Q1 also includes a digital controller that calculates the amount of power received by the mobile device within the limits set by the WPC v1.2 standard. The controller then communicates this information to the transmitter (TX) to allow the TX to determine if a foreign object is present within the magnetic interface and introduces a higher level of safety within magnetic field. This Foreign Object Detection (FOD) method is part of the requirements under the WPC v1.2 specification.
