WCT100xA Wireless Power Transmitter Controllers

NXP Semiconductors WCT100xA Wireless Power Transmitter Controllers integrate all required functions for WPC "Qi" compliant wireless power transmitter design. The WCT100xA Transmitter ICs manage the power transfer by receiving commands from the receiver. Receivers are detected by using either standard protocol methods or NXP touch sensor technology. Once the mobile device is detected, the WCT100xA controls the power transfer by adjusting rail voltage or phase shift of power stage according to message packets sent by mobile device. To maximize the design freedom and product differentiation, the WCT100xA Controllers support any 5W coil topology capable of supporting WPC Qi-based implementation. In addition, these devices support both WPC and PMA protocols. The WCT100xA Controllers also include CAN/LIN/IIC/SCI/SPI interfaces, over-voltage/current/temperature protection, and FOD method to protect from overheating by misplaced metallic foreign objects. They also handle any system fault and operation status, and provides comprehensive indicator outputs for robust system design.
