The series of MWCT2xx2A is an automotive wireless power transmitter controller that integrates all required functions for Wireless Power Consortium (WPC) Qi compliant wireless power transmitter design. It is a safe and secure device which utilizes the DSASS security module to support on-chip Qi authentication. To maximize the design flexibility and product differentiation, this family supports both WPC's baseline power profile and extended power profile in automotive/industrial/consumer power transmitter designs, using the fixed operation frequency control methods such as rail voltage control, phase shift control or duty cycle control etc. In addition, the easy-to-use NXP's FreeMASTER GUI tool has configuration, calibration and debugging functions to provide the user-friendly design experience and reduce time-to-market. This family supports up to 2 digital demodulation modules to reduce the external components, up to 2 FSK modulation modules to support two-way communication, protection module to perform the over- voltage/ current/temperature protection, FOD module to provide the protection of overheating by misplaced metallic foreign objects on each charging pad, and general I2C/SCI/SPI interfaces for external communications. It is also able to process any abnormal condition and operational status, and provides comprehensive indicator outputs for robust system design.
