Freescale Semiconductor Document Number: WCT1101DS Data Sheet Rev. 1.0, 02/2014 Consumer Low Power Wireless Overview Description Transmitter Controller The WCT1101 is a wireless power transmitter controller that Features integrates all required functions for WPC Qi compliant wireless power transmitter design. Its an intelligent device Low power (5 W) solution for Wireless Power to work with Freescale touch sensing technology or use Consortium (WPC) compliant transmitter design periodically analog PING (configurable by user) to detect a Conforms to the latest version low power WPC mobile device for charging while gaining super low standby specifications power. Once the mobile device is detected, the WCT1101 Supports wide DC input voltage range starting from controls the power transfer by adjusting the operation 4.2 V, typically 5 V, 12 V and 19 V frequency and duty cycle, or rail voltage, or phase shift of Integrated digital demodulation on chip power stage according to message packets sent by mobile Supports all types of receiver modulation strategies (AC device. capacitor, AC resistor and DC resistor) To maximize the design freedom and product differentiation, Supports Foreign Object Detection (FOD) WCT1101 supports any low power consumer power Super low standby power by Freescale Touch transmitter design (WPC A/B types or customization) using technology frequency and duty cycle control, or rail voltage control or Supports any low power consumer power transmitter phase shift control by software based solution. Besides, solutions using frequency and duty cycle control, or rail easy-to-use FreeMASTER GUI tool with configuration, voltage control or phase shift control calibration and debugging functions provides user-friendly LED & buzzer for system status indication design experience and speed time-to-market. Over-voltage/current/temperature protection Supports CAN/IIC/SCI/SPI interfaces The WCT1101 includes digital demodulation module to Software based solution to provide maximum design reduce external components, over-voltage/current/ freedom and product differentiation temperature protection, FOD method to protect from overheating by misplaced metallic foreign objects and FreeMASTER GUI tool to enable configuration, calibration and debugging general CAN/IIC/SCI/SPI interfaces for external communication purpose. It also handles any abnormal Applications condition and operational status, and provides comprehensive indicator outputs for robust system design.
