MWCT1000CFM

The WCT1000 is a wireless power transmitter controller that integrates all required functions for WPC “Qi” compliant wireless power transmitter design. It’s an intelligent device to work with Freescale touch sensing technology or use periodically analog PING (configurable by user) to detect a mobile device for charging while gaining super low standby power. Once the mobile device is detected, the WCT1000 controls the power transfer by adjusting operation frequency of power stage according to message packets sent by mobile device. In order to maximize the design freedom and product differentiation, WCT1000 supports any low power guided positioning single coil power transmitter design (WPC types or customization) using operation frequency and duty cycle control by software based solutions. Besides, easy-to-use FreeMASTER GUI tool with configuration, calibration and debugging functions provides user-friendly design experience and speed time-to-market. The WCT1000 includes digital demodulation module to reduce external components, over-voltage/current/ temperature protection and FOD method to protect from overheating by misplaced metallic foreign objects. It also handles any abnormal condition and operational status, and provides comprehensive indicator outputs for robust system design.
