MWCT1001AVLH

The MWCT1001AVLH from NXP Semiconductors is a highly integrated wireless power transmitter controller designed for automotive applications. It implements a complete WPC Qi-compliant wireless charging transmitter with a 32-bit DSP core, supporting both WPC and PMA protocols. The controller manages power transfer by receiving commands from the receiver and adjusting rail voltage or phase shift accordingly. It includes CAN, LIN, I2C, SCI, and SPI interfaces for system integration, along with Foreign Object Detection (FOD) to prevent overheating from misplaced metallic objects.

The MWCT1001AVLH operates as a complete wireless power transmitter controller. The 32-bit DSP core executes the WPC Qi protocol stack, managing the power transfer process from receiver detection through negotiation to power delivery. The device detects receivers using standard protocol methods or touch sensor technology. During power transfer, it demodulates messages from the receiver on-chip and adjusts the power stage rail voltage or phase shift accordingly. The FOD algorithm monitors system efficiency and temperature to detect and respond to foreign metallic objects. Multiple protection mechanisms including over-voltage, over-current, and over-temperature ensure safe operation.
