Product details
Overview
MWCT20D2VLH from NXP Semiconductors is an AEC-Q100 qualified automotive wireless power transmitter controller implementing WPC Qi Baseline (BPP), Extended (EPP), and Magnetic Power Profile (MPP) compliance. It integrates a 100 MHz 56800EX 32-bit DSC core, on-chip DSASS security module for Qi authentication, dual digital demodulation (DDM) and FSK modulation channels, and comprehensive protection including over-voltage/current/temperature and calibrated Q-factor-based foreign object detection (FOD). It operates across 5–48 V DC input and targets single/multi-coil in-vehicle charging systems.
For engineers reviewing the MWCT20D2VLH datasheet, MWCT20D2VLH pinout, MWCT20D2VLH application, or MWCT20D2VLH equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in automotive wireless charging, and validated alternative parts with documented functional and packaging differences - all grounded in NXP's Rev. 2.2 datasheet and official product family documentation.
Technical Context
The MWCT20D2VLH implements a dual-channel architecture supporting up to two independent resonant power transmitters via integrated digital demodulation and FSK modulation modules. Its 56800EX DSC core runs at 100 MHz in fast mode and executes real-time control of rail voltage, phase shift, or duty cycle for precise power regulation under BPP/EPP/MPP protocols.
It embeds hardware-accelerated Q-factor sensing, ASK/FSK bidirectional communication, and a DSASS security engine enabling on-chip Qi authentication without external crypto ICs. All protection logic - including FOD, over-temperature, over-current, and over-voltage - is implemented in firmware with dedicated analog front-end inputs and configurable thresholds.

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 |
|---|---|---|---|
| MWCT20D2AVLH | Includes on-chip authentication (DSASS); MWCT20D2VLH lacks DSASS but retains full Qi protocol stack and BPP/EPP/MPP support | Required where WPC-compliant authentication is mandatory (e.g., premium OEM programs); not needed for proprietary or basic BPP-only systems | Select MWCT20D2AVLH if Qi certification and secure handshake are required; MWCT20D2VLH suffices for cost-sensitive, non-certified implementations. |
| MWCT2012AVLH | Same package and pinout; differs in Flash (128 KB vs. 128 KB), RAM (20 KB vs. 20 KB), but omits dual DDM and dual FSK - single-channel only | Suitable for single-coil, lower-power (≤5 W) applications; cannot support multi-coil or simultaneous dual-receiver operation | Choose MWCT2012AVLH only for entry-level single-pad designs; MWCT20D2VLH is required for any dual-coil, EPP, or MPP use case. |
Compared with MWCT20D2AVLH, MWCT20D2VLH removes the DSASS security module but retains identical timing, power control, and communication capabilities - making it ideal for cost-optimized automotive transmitters where authentication is handled externally or omitted. Against MWCT2012AVLH, MWCT20D2VLH adds full dual-channel hardware resources, enabling true multi-coil scalability without firmware workarounds.

FAQ
What is the core processor architecture used in the MWCT20D2VLH?
The MWCT20D2VLH integrates a 56800EX 32-bit Digital Signal Controller (DSC) core operating at up to 100 MHz in fast mode. This architecture combines DSP acceleration (including single-cycle 32×32→64-bit MAC) with controller peripherals like eFlexPWM and QSCI, enabling real-time closed-loop control of resonant power stages. The MWCT20D2VLH leverages this core to execute Qi protocol stacks, FOD algorithms, and power regulation without external co-processors.
Does the MWCT20D2VLH support WPC Qi Extended Power Profile (EPP)?
Yes, the MWCT20D2VLH fully supports WPC Qi Extended Power Profile (EPP) through its integrated firmware stack and dual-channel digital demodulation. It negotiates up to 15 W output with EPP-compliant receivers using FSK communication and dynamically adjusts power delivery based on receiver feedback. The MWCT20D2VLH achieves this without external protocol ICs - all EPP state machine logic resides on-die.
What is the difference between MWCT20D2VLH and MWCT20D2AVLH?
The MWCT20D2VLH and MWCT20D2AVLH share identical pinout, package, memory, and peripheral configuration, but MWCT20D2AVLH includes the on-chip DSASS security module for WPC Qi authentication, whereas MWCT20D2VLH omits DSASS. Both support BPP/EPP/MPP protocols and dual-channel operation. The MWCT20D2VLH is intended for applications where authentication is handled externally or not required, reducing cost and silicon area.
Can the MWCT20D2VLH drive multiple transmitter coils simultaneously?
Yes, the MWCT20D2VLH supports up to two independent transmitter coils using its dual digital demodulation (DDM) and dual FSK modulation modules. Each channel processes ASK/FSK communication and Q-factor sensing separately, coordinated via the internal inter-module crossbar. This allows true concurrent operation - for example, charging a smartphone on one pad while powering a smartwatch on another - without time-slicing or performance degradation.
What debug and configuration tools are supported for the MWCT20D2VLH?
The MWCT20D2VLH is fully supported by NXP's FreeMASTER GUI tool via QSCI or USB-to-SCI bridge. FreeMASTER enables real-time parameter tuning (e.g., FOD thresholds, power setpoints), coil calibration, waveform capture, and firmware updates without halting operation. JTAG/EOnCE pins (TCK/TMS/TDI/TDO) provide full-cycle debugging, register inspection, and flash programming - all accessible directly on the MWCT20D2VLH evaluation hardware.
