WCT101XADS Datasheet Wireless Power Transmitter Controller

Manufacturer: NXP Semiconductors

Overview: NXP Semiconductors Data Sheet WCT101XADS.

General Description

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.

Key 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 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) frame.
