Product details
Overview
MWCT20D2AVLH from NXP Semiconductors is an AEC-Q100 qualified automotive wireless power transmitter controller IC 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) channels, and dual FSK modulation modules - enabling secure two-way communication and multi-coil support in vehicle-mounted charging systems.
For engineers reviewing the MWCT20D2AVLH datasheet, MWCT20D2AVLH pinout, MWCT20D2AVLH application, or MWCT20D2AVLH equivalent, this page delivers verified technical context including rail-voltage-controlled frequency regulation, Q-factor-based foreign object detection (FOD), integrated 12-bit ADCs with differential sensing, and LIN-compliant QSCI interface for automotive console integration.
Technical Context
The MWCT20D2AVLH implements a dual-core control architecture: a 100 MHz 56800EX DSC handles real-time power regulation, coil selection, and Qi protocol stack execution, while dedicated hardware modules perform ASK/FSK demodulation, rail-voltage-controlled frequency tuning, and calibrated Q-factor sensing for FOD. Its 54 GPIOs include four configurable op-amps and two 12-bit cyclic ADCs with programmable gain amplifiers for resonant tank current/voltage monitoring.
It supports 5–48 V DC input via external full-bridge drivers, uses internal LDOs to generate 5 V and 3.3 V rails, and integrates dual eFlexPWM submodules with NanoEdge resolution (312 ps edge placement) for precise phase-shift and duty-cycle control of resonant inverters - critical for maintaining efficiency across varying coil coupling and load conditions.

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 |
|---|---|---|---|
| STWBC2-HP | ARM Cortex-M0+ core (48 MHz), single DDM channel, no on-chip Qi authentication - requires external secure element | Targeted at consumer-grade single-coil transmitters; lacks AEC-Q100 qualification and LIN interface | Lower-cost option for non-automotive BPP-only applications where security and dual-coil support are not required |
| MP-A21 Reference Design (with MWCT2012AVLH) | Same MWCT2xx2A family but with 2012A variant: no on-chip authentication, lower flash (128 KB vs same), identical pinout and peripheral set | Used in cost-optimized automotive transmitters where OEM mandates external authentication or proprietary protocols | Drop-in replacement for MWCT20D2AVLH in footprint- and firmware-compatible designs where DSASS is not needed |

FAQ
What wireless charging standards does the MWCT20D2AVLH support?
The MWCT20D2AVLH supports WPC Qi Baseline Power Profile (BPP), Extended Power Profile (EPP), and Magnetic Power Profile (MPP) - all validated per the official NXP MWCT2XX2A Rev. 2.2 datasheet. It also enables customer proprietary protocols through its programmable DSC core and flexible modulation interfaces. The MWCT20D2AVLH does not support AirFuel Resonant or PMA standards.
Does the MWCT20D2AVLH include built-in Qi authentication hardware?
Yes, the MWCT20D2AVLH integrates the DSASS (Digital Secure Authentication and Signature System) security module, which performs on-chip cryptographic authentication required by WPC Qi specifications. This eliminates the need for external secure elements in BPP/EPP/MPP implementations. The MWCT20D2AVLH's DSASS is enabled by default and certified per WPC test plan v1.3.1.
What is the maximum input voltage range supported by the MWCT20D2AVLH?
The MWCT20D2AVLH supports a DC input voltage range of 5 V to 48 V - verified in the "Operation Parameters" section of the Rev. 2.2 datasheet. This allows direct integration with 12 V, 24 V, and 48 V automotive battery systems without external pre-regulation. The MWCT20D2AVLH itself operates from internal 3.3 V and 5 V LDOs derived from the input rail.
How many coils can the MWCT20D2AVLH control simultaneously?
The MWCT20D2AVLH supports multi-coil configurations via software-controlled coil selection logic and dual digital demodulation channels - enabling up to two independent charging zones (e.g., dual-pad center console). Figure 2 of the datasheet confirms dual-transmitter system operation. The MWCT20D2AVLH does not support three or more concurrent coils without external multiplexing hardware.
Is the MWCT20D2AVLH pin-compatible with other MWCT2xx2A family members?
Yes, the MWCT20D2AVLH shares the same 64-pin LQFP package and pinout with MWCT2012AVLH and MWCT20D2VLH - confirmed in Table 1 and Section 4 (Pinout) of the Rev. 2.2 datasheet. This enables hardware reuse across variants differing in authentication capability (D2A vs D2 vs 12A) and temperature grade, with only firmware and configuration changes required.
