WCT1111DS NXP Semiconductors
●Overview Description
■The WCT1111is a wireless power transmitter controller that integrates all required functions for WPC “Qi” compliant wireless power transmitter design. It is an intelligent device that works with the NXP touch sensing technology or uses periodically analog PING to detect a mobile device for charging while gaining super low standby power. Once the mobile device is detected, the WCT1111 controls the power transfer by adjusting the operation frequency and duty cycle, or switching topology, or adjusting the phase difference of the power stage according to message packets sent by the mobile device.
■Tomaximize the design freedom and product differentiation, the WCT1111 supports the extended power profile consumer power transmitter design (WPCMP-Ax types, MP-Bx types or customization) using operation frequency and duty cycle control, phase difference control and topology switch by software based solution, which can support wireless charging with both extended power profile power receiver and baseline power profile power receiver. In addition, the easy-to-use FreeMASTER GUI tool has configuration, calibration and debugging functions to provide the user-friendly design experience and reduce time-to-market.
■The WCT1111 includes a digital demodulation module to reduce the external components,an FSK modulation module to support two-way communication, a protection module to handle the over-voltage/current/temperature protection,an FOD module to protect from overheating by misplaced metallic foreign objects,and general CAN/IIC/SCI/SPI interfaces for external communications. It also handles any abnormal condition and operational status and provides comprehensive indicator outputs for robust system design.
