Document Number: WCT101XADS  
NXP Semiconductors  
Data Sheet  
Rev. 0 09/2016  
Overview Description  
WCT101XADS  
Features  
The WCT101xA 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 WCT101xA  
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.  
Compliant with the latest version Wireless Power  
Consortium (WPC) power class 0 specification power  
transmitter design  
Supports wide transmitter DC input voltage range of 6V  
(limited duration at Start/Stop operation) to 16V  
Integrated digital demodulation  
Supports two-way communication, transmitter to  
receiver by FSK and receiver to transmitter by ASK  
Supports Q factor detection and calibrated power loss  
based Foreign Object Detection (FOD) framework  
Supports low standby power  
Uses rail voltage control, phase difference control or  
duty cycle control with the fixed operation frequency to  
alleviate EMI in automotive system  
Supports key FOB avoidance function  
Supports operation frequency dithering technology to  
eliminate AM band interference  
Supports CAN/LIN/IIC/SCI/SPI interfaces  
LED for system status indication  
Over-voltage/current/temperature protection  
Software based solution to provide maximum design  
freedom and product differentiation  
To maximize the design freedom and product differentiation,  
the WCT101xA supports the extended power profile  
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 WCT101xA 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.  
AECQ-100 grade 2 certification
