Freescale WCT1000 5W单线圈无线充电器参考设计

Freescale公司的WCT1000是无线电源发送器控制器,集成了WPC Qi兼容的无线电源发送设计所需的所有功能,是低功率5W解决方案.单电源输入4.2V起,典型值为5V,12V和19V,采用Freescale Touch技术得到超低待机功耗,低于25mW.本文介绍了WCT1000主要特性, 无线充电系统功能框图, WCT1000功能框图, 无线发送系统设计案例电路图以及单线圈无线充电器参考设计WCT-5W1COILTX主要特性和优势,框图,电路图和材料清单.

The WCT1000 is a wireless power transmitter controller that integrates all required functions for WPC “Qi” compliant wireless power transmitter design. It’s an intelligent device to work with Freescale touch sensing technology or use periodically analog PING (configurable by user) to detect a mobile device for charging while gaining super low standby power. Once the mobile device is detected, the WCT1000 controls the power transfer by adjusting operation frequency of power stage according to message packets sent by mobile device.
