Product details
Overview
MWCT2012AVLH 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 56800EX 32-bit DSC core (100 MHz fast mode), on-chip DSASS security module for Qi authentication, dual digital demodulation (DDM) channels, dual FSK modulation modules, and hardware-based Foreign Object Detection (FOD) with Q-factor sensing - deployed in vehicle cabin wireless charging systems supporting single/multi-coil topologies.
For engineers reviewing the MWCT2012AVLH datasheet, MWCT2012AVLH pinout, MWCT2012AVLH application, or MWCT2012AVLH equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C automotive temperature grade, 5 V–48 V wide DC input support, integrated rail voltage/phase shift/duty cycle control for resonant power regulation, and dual-transmitter system capability via coil multiplexing and crossbar-peripheral synchronization.
Technical Context
The MWCT2012AVLH implements a dual-core timing architecture: a 56800EX DSC core executing real-time power control loops at up to 100 MHz, and dedicated hardware accelerators for ASK/FSK demodulation, Q-factor sensing, and FOD decision logic. Its peripheral crossbar (XBAR) enables deterministic signal routing between eFlexPWM, ADCs, comparators, and communication interfaces without CPU intervention.
It supports three distinct Qi power profiles through configurable firmware-controlled modulation schemes and resonant frequency tuning - BPP (5 W), EPP (15 W), and MPP (up to 30 W) - with all profile switching handled in software via I²C/SCI/SPI commands and validated by on-chip cryptographic authentication against WPC-compliant receivers.
Key Specifications
