FAQ
What is the primary function of the MWCT1003AVLHR in an automotive wireless charging system?
The MWCT1003AVLHR serves as the complete transmitter controller IC for Qi Baseline Power Profile wireless charging in vehicles. It executes digital demodulation, foreign object detection, coil selection, power regulation, and communication with receiving devices-all while interfacing natively with vehicle networks via CAN and LIN. The MWCT1003AVLHR integrates these functions into a single AEC-Q100 Grade 2 qualified device to eliminate external components and simplify system design.
Does the MWCT1003AVLHR support over-the-air firmware updates?
Yes, the MWCT1003AVLHR supports field firmware updates via its SPI or CAN interface, enabled by its 246 KB flash memory and on-chip EEPROM for storing update metadata and calibration data. This capability allows OEMs to deploy feature enhancements, security patches, or regional compliance adjustments post-production without hardware revision. The MWCT1003AVLHR firmware architecture is built around API-accessible modules that facilitate modular, tested updates without full image reflash.
How does the MWCT1003AVLHR achieve compliance with WPC Qi Baseline Power Profile?
The MWCT1003AVLHR achieves Qi Baseline Power Profile compliance through integrated hardware blocks-including on-chip digital demodulation, precise timing generation, and analog sensing front-ends-combined with NXP-provided production firmware implementing the full Qi communication stack, state machine, and power control algorithms. All MWCT1003AVLHR units ship with pre-validated firmware meeting WPC v1.2.4 requirements, and the MWCT1003AVLHR's run-time calibration ensures sustained compliance across temperature and aging.
What distinguishes the MWCT1003AVLHR from the MWCT1001AVLHR beyond memory size?
Beyond its larger 246 KB flash, the MWCT1003AVLHR includes EEPROM for persistent parameter storage, additional GPIOs for custom peripheral control, and enhanced I/O routing flexibility for multi-coil layout optimization. These resources enable OEM-specific firmware layers, field-upgradable calibration data, and differentiated user experiences-capabilities absent in the MWCT1001AVLHR. The MWCT1003AVLHR is therefore the only variant supporting true end-product differentiation in production automotive programs.
Is external circuitry required for foreign object detection (FOD) with the MWCT1003AVLHR?
No external FOD circuitry is required. The MWCT1003AVLHR implements full WPC-compliant FOD using its integrated analog sensing channels, DSP-based signal analysis, and dedicated firmware algorithm-all operating within the device. The MWCT1003AVLHR performs real-time impedance and Q-factor monitoring across operating frequencies, triggering shutdown within defined time limits upon detection. This self-contained FOD implementation meets ISO/IEC 62368-1 and WPC safety requirements without added components.
