NXP Semiconductors WCT100xA 无线功率发射器控制器

飞思卡尔 WCT100xA 是一款无线功率发射器控制器,集成了 WPC “Qi”兼容无线功率发射器设计所需的全部功能。WCT100xA 发射器 IC 通过从接收器接收命令来管理功率传输。接收器的检测是通过使用标准协议方法或者飞思卡尔的触摸传感器技术实现的。一旦检测到移动设备,WCT100xA 便可控制功率传输,方法是根据移动设备发送的信息包调节轨电压或功率级的相移。为最大限度提高设计自由度和产品差异化,WCT100xA 支持任何能支持基于 WPC Qi 实现的 5W 线圈拓扑结构。此外,系统还支持 WPC 和 PMA 这两种协议。WCT100xA 还包括 CAN/LIN/IIC/SCI/SPI 接口、过压/过流/过温保护及 FOD 方法,以防被错误放置的金属异物过度加热。它还可应对任何系统故障和工作状态,并提供全面的指示器输出,从而实现强大的系统设计。
