Wireless Charging Transmitter by NXP Semiconductors

The WCT101XDS from NXP Semiconductors is a Wireless Power Transmitter Controller that supports WPC’s Qi power transmitter design. It is an intelligent device that works with the NXP touch sensing technology and uses periodic analog PINGs to detect a mobile device for charging while consuming very low standby power.

The power transmitter uses rail voltage control, phase difference control or duty cycle control with the fixed operation frequency to alleviate EMI in the EMI sensitive system. This transmitter supports operation frequency dithering technology to eliminate interference with specific frequency band electronic devices and wide transmitter DC input voltage range of 5 to 24 V.

The WCT101XDS includes a digital demodulation module to reduce the external components, a FSK modulation module to support two-way communication, a protection module to handle the over-voltage/ current/ temperature protection, a FOD module to protect from overheating by misplaced metallic foreign objects, and general CAN/IIC/SCI/SPI interfaces for external communications. It is suitable for industrial/ consumer extended power profile power transmitter applications.
