The MWCT1013A from NXP Semiconductors is an Automotive-Qualified Wireless Transmitter Controller that has been designed to be compliant with the latest WPC Qi specifications. It delivers an output power up to 15 W. This IC functions based on NXP’s touch sensing technology or uses periodically analog PING to detect mobile devices on the charging pad and once detected, it transfers the power by adjusting the rail voltage, phase difference, or the duty cycle. It supports WPC's baseline and extended power profiles, offering flexibility in automotive, industrial, and consumer transmitter designs with control methods like rail voltage, phase shift, and duty cycle control. This coil controller features integrated protection to prevent over-voltage, over-current, and over-temperature conditions. It also supports a foreign object detection (FOD) module to avoid overheating due to misplaced metallic objects.
This AEC-Q100-qualified coil includes general CAN/IIC/SCI/SPI interfaces for external communication and comprehensive indicator outputs for robust system design. It supports low standby power, operation frequency dithering to minimize peak emissions, LED system status indicators, and a software-based solution for design flexibility and product upgrades without reworking the hardware. This coil is available in a surface-mount package and is ideal for automotive wireless power transfer applications.
