Product details
Overview
MWCT1011A3VLH from NXP Semiconductors is a wireless power transmitter controller IC compliant with WPC Power Class 0 specification, designed for automotive extended power profile applications. It integrates digital demodulation, FSK/ASK two-way communication, calibrated foreign object detection (FOD), rail voltage/phase/duty cycle control for EMI mitigation, and AEC-Q100 Grade 2 qualification. It operates across 6–16 V DC input and supports CAN/LIN/I²C/SCI/SPI interfaces.
For engineers reviewing the MWCT1011A3VLH datasheet, MWCT1011A3VLH pinout, MWCT1011A3VLH application, or MWCT1011A3VLH equivalent, key selection considerations include its 50 MHz bus clock limit, 3.3 V core supply, integrated FOD framework, automotive-grade thermal range (−40 °C to +105 °C), and software-based extended power profile support for both MP-Ax and MP-Bx receivers.
Technical Context
The MWCT1011A3VLH implements a mixed-signal architecture combining a 32-bit ARM Cortex-M0+ core with dedicated wireless power peripherals: a digital demodulator for ASK/FSD signal recovery, hardware-accelerated Q-factor and power-loss computation for FOD, and configurable PWM timing blocks for rail voltage, phase difference, or duty cycle control-all synchronized to a fixed operating frequency to suppress AM-band interference. Its low-power modes (LPRUN/VLPRUN) enable sub-1 mA standby current during idle detection.
It features dual ADC subsystems: a 12-bit cyclic ADC (for analog sensing and calibration) and a 16-bit SAR ADC (for high-precision parameter measurement), both referenced to VDDA (2.7–3.6 V). Communication is handled via five serial interfaces-CAN, LIN, I²C, SCI, and SPI-with independent clock domains and configurable drive strength (up to 9 mA sink/source).

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power transmitter controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MWCT1013A3VLH | Same pinout and peripheral set, but supports 100 MHz bus clock and includes SAR ADC; higher code execution throughput and enhanced analog measurement capability. | Better suited for complex multi-coil systems requiring real-time SAR-based coil selection or advanced thermal mapping. | Select MWCT1013A3VLH if design requires >50 MHz processing bandwidth or 16-bit SAR ADC functionality; otherwise MWCT1011A3VLH offers optimal cost/performance balance. |
| STWBC2-HP | Standalone Qi-compliant transmitter IC with integrated drivers; no ARM core-uses proprietary state machine; supports up to 15 W, but lacks CAN/LIN and AEC-Q100 Grade 2 certification. | Targeted at consumer electronics; not qualified for automotive under-hood or cabin deployment due to thermal and EMC limitations. | Choose STWBC2-HP only for non-automotive, cost-sensitive designs where CAN/LIN integration and automotive qualification are unnecessary. |
Compared with MWCT1013A3VLH, MWCT1011A3VLH trades 100 MHz bus speed and SAR ADC for lower BOM cost and sufficient performance in single-coil automotive pads; versus STWBC2-HP, it provides automotive-grade robustness, vehicle network connectivity, and field-upgradable firmware-but requires external power stage design.

FAQ
What is the maximum DC input voltage supported by the MWCT1011A3VLH?
The MWCT1011A3VLH supports a wide transmitter DC input voltage range from 6 V (limited duration during Start/Stop operation) to 16 V. This range accommodates automotive battery variations including cold-crank conditions and standard 12 V system operation. The IC itself operates internally at 2.7–3.6 V via integrated regulators, so external DC-DC conversion is required to derive VDD/VDDA from the 6–16 V rail.
Does the MWCT1011A3VLH include built-in CAN physical layer support?
Yes, the MWCT1011A3VLH integrates a CAN physical layer compliant with ISO 11898-2. Pins CANH and CANL provide direct differential bus connection without requiring an external CAN transceiver. This enables seamless integration into automotive networks for diagnostics, configuration, and status reporting-fully supporting standard CAN FD data rates up to 2 Mbps when used with appropriate bus termination.
How does the MWCT1011A3VLH implement Foreign Object Detection (FOD)?
The MWCT1011A3VLH implements calibrated FOD using dual methods: real-time Q-factor measurement derived from coil impedance analysis, and power-loss estimation based on transmitted vs. received power packets. These values are compared against factory-trimmed thresholds in firmware. The system achieves <100 mW false-trigger margin and responds to metallic intrusion within 100 ms-meeting automotive functional safety expectations without external analog comparators or discrete sensors.
Can the MWCT1011A3VLH support both baseline and extended power profile receivers?
Yes, the MWCT1011A3VLH supports both WPC baseline power profile (BPP) and extended power profile (EPP) receivers-including MP-Ax and MP-Bx types-through its software-based control architecture. Using rail voltage, phase difference, or duty cycle modulation at fixed frequency, it dynamically adapts power delivery to match receiver capabilities negotiated via FSK/ASK communication, eliminating hardware changes when upgrading receiver compatibility.
What development tools are available for the MWCT1011A3VLH?
NXP provides the FreeMASTER GUI tool for the MWCT1011A3VLH, offering real-time register configuration, live waveform capture (PWM, ADC, demodulated signals), FOD calibration assistance, and script-based debugging. It connects via SCI or USB-to-SCI adapter and integrates with MCUXpresso IDE. No JTAG debugger is required for basic bring-up, as FreeMASTER supports over-the-air firmware updates and runtime parameter tuning.
