Supports MWCT1011BVLH MWCT1011B The WCT1011B is 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 WCT101x controls the power transfer by adjusting the rail voltage, the phase difference, or the duty cycle of the power stage according to message packets sent by the mobile device.
To maximize the design freedom and product differentiation, the WCT1011B supports the extended power profile industrial/consumer power transmitter design (WPC MP-Ax types, MP-Bx types or customization) using the fixed operation frequency control methods such as rail voltage control, phase difference control or duty cycle control etc. 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 WCT1011B 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.
