Freescale MWCT1213AVLH

控制器，无线电力发射器300µA2.7V ~ 3.6V

Overview

The WCT1200 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 WCT1200 controls the power transfer by adjusting the operation frequency of the power stage according to message packets sent by the mobile device. In order to maximize the design freedom and product differentiation, WCT1200 supports any low power free positioning multiple coils 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 WCT1200 includes digital demodulation module to reduce external components, dynamic input power limit function for power limited power supply input, 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.
