STMicroelectronics has launched a new family of integrated GaN-based smart power components aimed at improving efficiency, performance, and form factor in motor drive applications across consumer and industrial markets.
The new GaNSPIN system-in-package platform integrates high-voltage GaN transistors and gate drivers, delivering the benefits of wide-bandgap technology to motorized systems such as household appliances, power tools, and industrial equipment. This innovation allows manufacturers to reduce power losses, lower system costs, and design more compact modules.
The initial devices—GANSPIN611 and GANSPIN612—are designed for applications up to 400 W, such as compressors, pumps, and fans. Key features include:
- Integrated 650V GaN half-bridge and driver in a compact 9mm x 9mm QFN package
- Low RDS(on) (138mΩ for GANSPIN611, 270mΩ for GANSPIN612) to minimize conduction losses
- Optimized switching control to manage EMI and stress on motor windings
- Adjustable slew rates for system-level tuning
- Comprehensive protections, including UVLO, OVP, OCP, thermal shutdown, and interlocking
- Integrated bootstrap diode for simplified high-side drive
- Built-in standby function to support energy-saving modes
The GaNSPIN platform supports both 110V and 230V AC input systems, targeting universal appliance compatibility. By enabling heatsink-free operation in many cases, the devices help reduce board size by up to 60% and lower the bill of materials—key considerations in both cost-sensitive and space-constrained designs.
These latest GaN-based ICs from ST extend the benefits of wide-bandgap technology beyond power adapters and chargers, bringing new levels of efficiency and integration to motion control systems in a broad range of applications.
