Document Number: WCT101XDS NXP Semiconductors Data Sheet Rev. 1.2 05/2019 , The WCT101x is a wireless power transmitter controller WCT101XDS that integrates all required functions for WPC Qi compliant wireless power transmitter design. It is an Features intelligent device that works with the NXP touch sensing technology or uses periodically analog PING to detect a Compliant with the latest version Wireless Power mobile device for charging while gaining super low standby Consortium (WPC) power class 0 specification power power. Once the mobile device is detected, the WCT101x transmitter design controls the power transfer by adjusting the rail voltage, the Supports wide transmitter DC input voltage range of 5 phase difference, or the duty cycle of the power stage V to 24 V according to message packets sent by the mobile device. Integrated digital demodulation Supports two-way communication, transmitter to To maximize the design freedom and product receiver by FSK and receiver to transmitter by ASK differentiation, the WCT101x supports the extended power Supports Q factor detection and calibrated power loss profile industrial/consumer power transmitter design (WPC based Foreign Object Detection (FOD) framework MP-Ax types, MP-Bx types or customization) using the Supports low standby power fixed operation frequency control methods such as rail Uses rail voltage control, phase difference control or voltage control, phase difference control or duty cycle duty cycle control with the fixed operation frequency control etc. by software based solution, which can support to alleviate EMI in the EMI sensitive system wireless charging with both extended power profile power Supports operation frequency dithering technology to receiver and baseline power profile power receiver. In eliminate interference with specific frequency band addition, the easy-to-use FreeMASTER GUI tool has electronic devices configuration, calibration and debugging functions to Supports CAN/IIC/SCI/SPI interfaces provide the user-friendly design experience and reduce LED for system status indication time-to-market. Over-voltage/current/temperature protection The WCT101x includes a digital demodulation module to Software based solution to provide maximum design reduce the external components, an FSK modulation freedom and product differentiation module to support two-way communication, a protection Applications module to handle the over-voltage/current/temperature protection, an FOD module to protect from overheating by Industrial/Consumer Extended Power Profile Power misplaced metallic foreign objects, and general Transmitter CAN/IIC/SCI/SPI interfaces for external communications. o WPC compliant or customer properties It also handles any abnormal condition and operational status and provides comprehensive indicator outputs for robust system design.
