LH MWCT1011B The WCT1011B 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 WCT101x 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.
