Document Number: WCT1111DS NXP Semiconductors Data Sheet Rev. 1.1 09/2016 , Overview Description WCT1111DS The WCT1111 is a wireless power transmitter controller that Features integrates all required functions for WPC Qi compliant wireless power transmitter design. It is an intelligent device Compliant with the latest version Wireless Power that works with the NXP touch sensing technology or uses Consortium (WPC) power class 0 specification power periodically analog PING to detect a mobile device for transmitter design charging while gaining super low standby power. Once the Supports wide transmitter DC input voltage ranging mobile device is detected, the WCT1111 controls the power from 4.2 V, typically 12 V and 19 V transfer by adjusting the operation frequency and duty cycle, Integrated digital demodulation or switching topology, or adjusting the phase difference of Supports two-way communication, transmitter to the power stage according to message packets sent by the receiver by FSK and receiver to transmitter by ASK mobile device. Supports all types of receiver modulation strategies (AC capacitor, AC resistor and DC resistor) To maximize the design freedom and product differentiation, Supports Q factor detection and calibrated power loss the WCT1111 supports the extended power profile based Foreign Object Detection (FOD) framework consumer power transmitter design (WPC MP-Ax types, MP-Bx types or customization) using operation frequency Supports low standby power and duty cycle control, phase difference control and Supports various power control techniques: operation topology switch by software based solution, which can frequency control, duty cycle control, phase difference support wireless charging with both extended power profile control and topology switch power receiver and baseline power profile power receiver. In LED for system status indication addition, the easy-to-use FreeMASTER GUI tool has Over-voltage/current/temperature protection configuration, calibration and debugging functions to Supports CAN/IIC/SCI/SPI interfaces provide the user-friendly design experience and reduce Software-based solution to provide maximum design time-to-market. freedom and product differentiation FreeMASTER GUI tool to enable configuration, The WCT1111 includes a digital demodulation module to calibration and debugging reduce the external components, an FSK modulation module to support two-way communication, a protection module to Applications handle the over-voltage/current/temperature protection, an FOD module to protect from overheating by misplaced Extended Power Profile Power Transmitter metallic foreign objects, and general CAN/IIC/SCI/SPI Extended power profile consumer power transmitter interfaces for external communications. It also handles any solution with operation frequency and duty cycle abnormal condition and operational status and provides control, phase difference control, and topology switch comprehensive indicator outputs for robust system design.
