The reference design uses the MWCT10xx transmitter controller IC, a device which integrates all the required functions of a wireless power-transmitter design that complies with the Wireless Power Consortium (WPC) Qi® standard.
The design incorporates the NXP Touch capacitive-sensing technology to detect a mobile device positioned ready for charging while consuming very little power in stand-by mode.
The WCT-15WTX1COILFF offers considerable freedom to the developer to differentiate the end-product design and to meet a range of application requirements. The MWCT101x controller supports the Extended Power Profile (EPP) for industrial and consumer power-transmitter designs of the MP-Ax or MP-Bx types or for custom applications.
It uses fixed-frequency control methods such as rail-voltage control, phase-difference control or duty-cycle control. This software- based solution supports wireless charging for both EPP and baseline power profile receivers.
In addition, the easy- to-use FreeMASTER GUI offers configuration, calibration and debugging functions to provide a user-friendly design environment and to reduce development time.
