Product details
Overview
MWCT22C3AVLH from NXP Semiconductors is an AEC-Q100 qualified 32-bit digital signal controller (DSC) for WPC Qi-compliant wireless power transmitters, featuring a 100 MHz 56800EX core, 256 KB flash with ECC, 64 KB RAM, dual 12-bit ADCs (2×8 external + 2 internal channels), and integrated FSK/ASK modulation for bidirectional communication in automotive and industrial charging systems.
For engineers reviewing the MWCT22C3AVLH datasheet, MWCT22C3AVLH pinout, MWCT22C3AVLH application, or MWCT22C3AVLH equivalent, this device supports dual-transmitter control, Q-factor-based foreign object detection (FOD), rail voltage/phase shift/duty cycle frequency control methods, CAN-FD, dual I²C, three QSCI, two QSPI, and NanoEdge PWM with 312 ps resolution - all within a 100-pin LQFP package rated for −40°C to +105°C operation.
Technical Context
The MWCT22C3AVLH integrates a 56800EX DSC core delivering 100 MIPS at 100 MHz, combining DSP efficiency with MCU programmability. It implements dual eFlexPWM modules with NanoEdge high-resolution timing (312 ps edge placement), enabling precise resonant frequency control for multi-coil wireless power topologies.
Its analog subsystem includes two synchronized 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers and four comparators with 8-bit DAC references - critical for real-time coil current/voltage sampling and FOD calibration. Communication is handled via one FlexCAN module supporting CAN-FD, two I²C/SMBus ports, three QSCI interfaces (with LIN slave), and two QSPI modules - all accessible through an inter-module crossbar for flexible signal routing.

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 |
|---|---|---|---|
| MWCT22C3AVLL | Same 100 MHz DSC core, 256 KB flash, 64 KB RAM, but 64-pin LQFP package and reduced peripheral set: only 2 QSCI (vs 3), 1 QSPI (vs 2), no USB, and no NanoEdge PWM on PWMB. | Suitable for single-coil, cost-sensitive BPP-only designs where CAN-FD and dual-transmitter FOD are not required. | Select MWCT22C3AVLL when board space and BOM cost are constrained and full EPP/multi-coil capability is unnecessary. |
| MWCT20C3AVLH | Same 100-pin LQFP package and temperature rating, but lower peripheral integration: only 2 QSCI, 1 QSPI, no USB, and no CAN-FD - uses standard CAN 2.0B instead. | Targeted at consumer-grade transmitters where automotive diagnostics and high-speed vehicle network integration are not needed. | Choose MWCT20C3AVLH for non-automotive applications requiring full feature set except CAN-FD and USB debug interface. |
Compared with MWCT22C3AVLH, MWCT22C3AVLL trades pin count and peripheral richness for compactness and cost, while MWCT20C3AVLH retains the same package but omits CAN-FD and USB - making MWCT22C3AVLH the only variant supporting full automotive-grade diagnostics, dual-transmitter FOD, and NanoEdge PWM precision in a single 100-pin solution.

FAQ
What is the maximum operating temperature specification for the MWCT22C3AVLH?
The MWCT22C3AVLH is rated for operation from −40°C to +105°C ambient temperature and is AEC-Q100 Grade 2 qualified. This specification ensures reliable performance in under-dash automotive environments and industrial enclosures where thermal management is critical. The device includes on-die temperature sensing and integrated over-temperature protection that triggers system shutdown before silicon limits are exceeded. All electrical parameters in the MWCT22C3AVLH datasheet are guaranteed across this full range.
Does the MWCT22C3AVLH support both Qi Baseline Power Profile (BPP) and Extended Power Profile (EPP)?
Yes, the MWCT22C3AVLH fully supports both WPC Qi Baseline Power Profile (BPP) and Extended Power Profile (EPP) specifications. Its integrated software library and hardware peripherals - including dual FSK/ASK modulators, high-speed ADCs for real-time power measurement, and NanoEdge PWM for precise frequency control - enable compliant negotiation, configuration, and power transfer up to 15 W per transmitter. The MWCT22C3AVLH also supports customer proprietary protocols alongside Qi, allowing differentiated fast-charge implementations.
How many wireless power transmitter coils can the MWCT22C3AVLH control simultaneously?
The MWCT22C3AVLH supports control of up to two independent wireless power transmitter coils, as confirmed by its dual-channel Q-factor detection, dual digital demodulation modules, and dual FSK modulation capability. Figures 1 and 2 in the MWCT2xx3A datasheet explicitly show single- and dual-transmitter system architectures using the MWCT22C3A variant. Each coil path uses shared ADC resources with time-multiplexed sampling, and the inter-module crossbar enables synchronized PWM and sensing across both channels.
What communication interfaces does the MWCT22C3AVLH provide for host processor integration?
The MWCT22C3AVLH provides FlexCAN (CAN-FD), two I²C/SMBus ports, three QSCI interfaces (with LIN slave capability), and two QSPI modules for host integration. These interfaces allow connection to automotive ECUs via CAN-FD for diagnostics and status reporting, to external sensors or secure elements via I²C, to debug consoles or host MCUs via QSCI, and to high-speed peripherals like FET drivers via QSPI. The inter-module crossbar permits flexible signal routing between these interfaces and internal peripherals like ADCs and PWMs.
Is the MWCT22C3AVLH pin-compatible with other members of the MWCT2xx3A family?
No, the MWCT22C3AVLH is not pin-compatible with MWCT20C3AVLH or MWCT2013AVLH. While all three share the 100-pin LQFP package, Table 1 in the MWCT2xx3A datasheet shows differing peripheral allocations - for example, MWCT2013AVLH has only 54 GPIOs versus 82 on MWCT22C3AVLH, and signal multiplexing differs across variants. Pin assignments for PWM, ADC, and communication interfaces are not identical. Engineers must consult the specific pinout diagrams in Section 3 of the MWCT2xx3A datasheet and validate layout compatibility for each part number.
