STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has announced the EVSTDRVG611MC GaN-based motor-control reference design board. This board enables driving household appliances and industrial drivers with over 600W of power without the need for a heatsink, contributing to product miniaturization and reduced development costs.
As a turnkey board, users can start evaluation immediately upon power-up. This reference design integrates ST's STDRIVEG611 GaN driver IC, discrete GaN power transistors, and the STM32G431 mixed-signal microcontroller. The Bill of Materials (BOM), schematics, and Gerber files for the low-cost two-layer printed circuit board (108 x 110mm) are available for download from the ST website.
ST's GaN High Electron Mobility Transistors (HEMTs) and GaN driver ICs are transforming power conversion, already deployed in chargers, adapters, and server PSUs to achieve efficiency and power density beyond silicon technology limits. The STDRIVEG611 gate driver on the EVSTDRVG611MC board is optimized for hard-switching to facilitate GaN operation in motor control. By combining this driver with 650V, 75mΩ GaN transistors, appliance designers can achieve industry-leading power ratings, smaller electronic modules, and improved reliability.
EVSTDRVG611MC can operate above 600W without a heatsink when connected to a DC supply. With an optional heatsink, the maximum power capacity can be further increased, providing flexible power ranges for appliances like washing machines, industrial servo drives, and other brushless DC (BLDC) motor applications. The STDRIVEG611 driver comes in a compact QFN package (5 x 4mm). The STM32G431 microcontroller, part of the STM32 family, features three analog amplifiers for shunt sensing, enabling a competitive BOM. Powered by an Arm® Cortex®-M4 core, it executes advanced control algorithms for real-time operation at high speeds.
Users can quickly evaluate the EVSTDRVG611MC board and start application development using ST’s Motor Control Workbench. This workbench includes tools such as a motor profiler and performance monitor to assist development, and significantly shortens development time by enabling automatic firmware generation. Users can achieve smooth and precise operation using Field Oriented Control (FOC) in both sensored and sensorless modes, with support for various feedback options including Hall sensors, incremental encoders, and absolute encoders.
The EVSTDRVG611MC is available through ST’s distributors or the eSTore, priced at approximately $125.06.
