NXP Semiconductors Document Number: WCT100XADS Data Sheet Rev. 1.2, 01/2021 Automotive Wireless Transmitter Overview Description Controller The WCT100xA is a wireless power transmitter controller that integrates all required functions for WPC Qi Features compliant wireless power transmitter design. The WCT100xA transmitter IC manages the power transfer by Conforms to the latest version WPC Qi specification receiving commands from the receiver. Receivers are Supports wide DC input voltage range of 6 V (limited detected by using either standard protocol methods or duration at Start/Stop operation) to 16 V for automotive Freescale touch sensor technology. Once the mobile device battery input is detected, the WCT100xA controls the power transfer by Supports Foreign Object Detection (FOD) adjusting rail voltage or phase shift of power stage according Low-power system standby available using Freescale to message packets sent by mobile device. Touch technology Provides free positioning solutions by using WPC A or To maximize the design freedom and product differentiation, B type multi-coil technology the WCT100xA supports any 5W coil topology capable of Uses rail voltage control or phase shift control with supporting WPC Qi-based implementation. In addition, the fixed operating frequency to control power transfer to system supports both WPC and PMA protocols. help alleviate automotive system interference Supports the key FOB avoidance function The WCT100xA also includes CAN/LIN/IIC/SCI/SPI Supports the operation frequency dithering technology interfaces, over-voltage/current/temperature protection and to eliminate the AM band interference FOD method to protect from overheating by misplaced Improved EMC performance for automotive metallic foreign objects. It also handles any system fault and certification operation status, and provides comprehensive indicator Supports CAN/LIN/IIC/SCI/SPI interfaces outputs for robust system design. LED for system status indication Over-voltage/current/temperature protection Software based solution to provide maximum design freedom and product differentiation Qualified to AEC100 Test Group A&B Dual-mode capable Applications Automotive Wireless Power Transmitter o WPC compliant Wireless Charging System Functional Diagram 2021 NXP B.V.
