NXP Semiconductors WCT101XDS Wireless Power Transmitter Controller

NXP Semiconductors WCT101XDS Wireless Power Transmitter Controller integrates all required functions for WPC “Qi” compliant wireless power transmitter designs. The WCT101XDS is an intelligent device that works with NXP touch sensing technology. The device also 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.

Features

  • Compliant with the latest version Wireless Power Consortium (WPC) power class 0 specification power transmitter design
  • Supports wide transmitter DC input voltage range of 5V to 24V
  • 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
  • LED for system status indication
  • Uses rail voltage control, phase difference control or duty cycle control with the fixed operation frequency to alleviate EMI in the EMI sensitive system
  • Supports operation frequency dithering technology to eliminate interference with specific frequency band electronic devices
  • Supports CAN/IIC/SCI/SPI interfaces
  • Over-voltage/current/temperature protection
  • Software based solution to provide maximum design freedom and product differentiation

Applications

  • Industrial/Consumer Extended Power Profile Power Transmitter
    • WPC compliant or customer properties
