Mingjiada Supply MWCT1014SFVLL (NXP) 15W AUTOSAR Wireless Charging Transmitter IC

Introduction:
Amidst the trend towards vehicle intelligence and enhanced in-car experiences, in-vehicle wireless charging technology is emerging as a key feature that major automotive manufacturers are racing to incorporate. As a global leader in secure connectivity solutions for embedded applications, NXP has launched the MWCT1014SFVLL 15W AUTOSAR wireless charging transmitter IC, providing automotive manufacturers with a highly integrated, highly reliable and AUTOSAR-compliant production-ready solution that significantly drives the adoption and evolution of in-vehicle wireless charging technology.

I. Product Overview: A High-Performance Wireless Charging Controller Designed for the Automotive Environment
The MWCT1014SFVLL is a 15W automotive-grade wireless charging transmitter control chip launched by NXP, belonging to the MWCT101xS series. Designed specifically for in-vehicle centre console wireless charging pads, this device integrates an ARM Cortex-M4F core and a complete Qi protocol stack, whilst supporting the AUTOSAR software architecture. It serves as a core solution for building highly reliable and efficient in-vehicle wireless charging systems.

III. Key Features: Redefining the Capabilities of In-Vehicle Wireless Charging
The MWCT1014SFVLL offers comprehensive support for automotive wireless charging applications through a rich feature set:
1. AUTOSAR Software Compatibility
This series of ICs provides comprehensive AUTOSAR software support, including AUTOSAR software and drivers. This enables the MWCT1014SFVLL to integrate seamlessly into automotive manufacturers’ AUTOSAR development frameworks, significantly reducing system integration complexity.
2. Multi-coil Free Positioning
The MWCT1014SFVLL supports multi-coil configurations, allowing mobile devices to charge effectively without needing to be precisely aligned with the centre of the charging area, thereby significantly enhancing the user experience.
3. Chip-Level Demodulation (On-Board Digital Demodulation)
With integrated on-chip digital demodulation technology, no external demodulator is required for signal processing at the receiving end, effectively reducing the bill of materials (BOM) and PCB footprint.
4. Fixed-Frequency Rail Voltage Control
The MWCT1014SFVLL employs fixed-frequency rail voltage control technology to achieve superior electromagnetic compatibility (EMC) performance, helping the system meet the CISPR 25 Class 5 standard—a critical automotive-grade EMC certification requirement for 15W systems.
5. Comprehensive Safety Protection
Multiple safety mechanisms are integrated, including overvoltage protection, overcurrent protection and thermal shutdown. It supports Foreign Object Detection (FOD) functionality; through Q-factor detection and power dissipation FOD methods, it can effectively identify metallic foreign objects and automatically cut off power transmission, thereby protecting user and vehicle safety.
6. Interference Avoidance and Immunity
Built-in interference avoidance functions for key fobs and the AM radio band ensure that the wireless charging process does not interfere with the vehicle’s other wireless communication systems.
7. Comprehensive In-Vehicle Communication Interfaces
The MWCT1014SFVLL supports CAN and LIN bus interfaces, facilitating data exchange and status reporting with systems such as vehicle gateways and body control modules.
8. NFC Functionality Expansion
Support for NFC interfaces enables convenient features such as rapid Bluetooth/Wi-Fi pairing, NFC smart vehicle access control, and NFC card damage protection.

IV. Typical Applications: From Single-Device to Multi-Device Smart Charging
The MWCT1014SFVLL is specifically designed for in-vehicle wireless charging applications, with its primary areas of application including:
1. Wireless charging in the vehicle centre console
As the core application scenario, the MWCT1014SFVLL can be integrated into the vehicle dashboard or centre console to provide convenient wireless charging services for drivers and passengers. The 15W multi-coil transmitter reference platform, based on the MWCT101xS controller IC family, has been Qi-certified and classified as an MP-A9 transmitter type.
2. Parallel Charging of Multiple Devices
NXP has pioneered the industry by enabling a single MWCT controller to simultaneously charge two mobile devices at 2x15W. Both passengers and the driver can enjoy wireless charging simultaneously from a single console, thereby reducing vehicle costs and minimising the number of physical pins required.
3. Wireless Charging Modules for Electric Vehicles (EVs)
The MWCT1014SFVLL is also suitable for in-vehicle wireless charging systems in electric vehicles, providing charging support for various consumer electronic devices within the vehicle.
