Document Number: WCT101XADS

NXP Semiconductors

Data Sheet

Rev. 0 09/2016

Overview Description

WCT101XADS

Features

The WCT101xA is a wireless power transmitter controller

that integrates all required functions for WPC “Qi”

compliant wireless power transmitter design. It is an

intelligent device that works with the NXP touch sensing

technology or uses periodically analog PING to detect a

mobile device for charging while gaining super low standby

power. Once the mobile device is detected, the WCT101xA

controls the power transfer by adjusting the rail voltage, the

phase difference, or the duty cycle of the power stage

according to message packets sent by the mobile device.



Compliant with the latest version Wireless Power

Consortium (WPC) power class 0 specification power

transmitter design

Supports wide transmitter DC input voltage range of 6V

(limited duration at Start/Stop operation) to 16V

Integrated digital demodulation

Supports two-way communication, transmitter to

receiver by FSK and receiver to transmitter by ASK

Supports Q factor detection and calibrated power loss

based Foreign Object Detection (FOD) framework

Supports low standby power

Uses rail voltage control, phase difference control or

duty cycle control with the fixed operation frequency to

alleviate EMI in automotive system

Supports key FOB avoidance function

Supports operation frequency dithering technology to

eliminate AM band interference

Supports CAN/LIN/IIC/SCI/SPI interfaces

LED for system status indication

Over-voltage/current/temperature protection

Software based solution to provide maximum design

freedom and product differentiation



To maximize the design freedom and product differentiation,

the WCT101xA supports the extended power profile

consumer power transmitter design (WPC MP-Ax types,

MP-Bx types or customization) using the fixed operation

frequency control methods such as rail voltage control,

phase difference control or duty cycle control etc. by

software based solution, which can support wireless

charging with both extended power profile power receiver

and baseline power profile power receiver. In addition, the

easy-to-use FreeMASTER GUI tool has configuration,

calibration and debugging functions to provide the



user-friendly design experience and reduce time-to-market.

The WCT101xA includes a digital demodulation module to

reduce the external components, an FSK modulation module

to support two-way communication, a protection module to

handle the over-voltage/current/temperature protection, an

FOD module to protect from overheating by misplaced

metallic foreign objects, and general CAN/IIC/SCI/SPI

interfaces for external communications. It also handles any

abnormal condition and operational status and provides

comprehensive indicator outputs for robust system design.



AECQ-100 grade 2 certification
