STMicroelectronics’ new GaN ICs platform for motion control boosts appliance energy ratings

Rhea-AI Summary

STMicroelectronics (NYSE: STM) launched a new GaN IC platform, GaNSPIN, for motion‑control motor drives on November 24, 2025, targeting white goods and factory automation.

The first devices, GANSPIN611 (in production) and GANSPIN612, support motors up to 400 W, use 650V GaN transistors, and offer RDS(on) of 138 mΩ (611) and 270 mΩ (612). GANSPIN611 ships in a 9mm×9mm thermally enhanced QFN from $4.44. ST says the SiP controls hard‑switching slew rates (nominal 10 V/ns) to reduce winding stress, cut EMI, and enable up to 60% circuit footprint reduction and heatsinkless designs for many applications.

ST's GaNSPIN platform extends GaN to motor drives, promising cost, size, and efficiency gains for appliances and automation.

ST leverages its GaNSPIN system-in-package to embed a driver and 650V GaN half-bridge for 3-phase BLDC motor control, targeting appliances and factory automation up to 400 Watts. The announcement lists concrete technical benefits: controlled hard-switching with adjustable turn-on dV/dt (nominal 10V/ns) for lower EMC stress, low RDS(on) values (GANSPIN611 138mΩ, GANSPIN612 270mΩ), integrated bootstrap diode, protections (UVLO, overvoltage, overcurrent, thermal, interlocking), wide supply range to 20V, and a standby pin for power saving. The company quotes production availability for GANSPIN611 and a unit entry price of $4.44, which supports near-term commercial adoption in cost‑sensitive white goods and some industrial drives.

Dependencies and risks include real-world thermal and EMC performance across diverse motor types and regulatory compliance; the release itself cites reduced need for heatsinks and up to 60% PCB footprint reduction but does not provide independent test data. Integration success will hinge on designers validating the adjustable dV/dt and fault-sensing behavior with target motors, and on supply/volume production scaling. Watch for customer design wins, published application notes with measured efficiency/EMC data, and supply ramp signals at industry events such as SPS on 25-27 November 2025; near-term indicators (next 6–12 months) will show whether the platform converts to measurable OEM engagements and incremental revenue.

STMicroelectronics’ new GaN ICs platform for motion control boosts appliance energy ratings

High-efficiency GaN power integrated technology tailored for motor drives in white goods and factory automation

Geneva, November 24, 2025 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has unveiled new smart power components that let home appliances and industrial drives leverage the latest GaN (gallium-nitride) technology to boost energy efficiency, increase performance, and save cost.

GaN power adapters and chargers available in the market can handle enough power for laptops and USB-C fast charging to achieve extremely high efficiency to meet stringent incoming eco-design norms. ST’s latest GaN ICs now make this technology applicable to motor drives for products like washing machines, hairdryers, power tools, and factory automation.

“Our new GaNSPIN system-in-package platform unleashes wide-bandgap efficiency gains in motion-control applications by introducing special features that optimize system performance and safeguard reliability,” said Domenico Arrigo, General Manager, Application Specific Products Division, STMicroelectronics. “The new devices enable future generations of appliances to achieve higher rotational speed for improved performance, with smaller and lower-cost control modules, lightweight form factors, and improved energy ratings.”

The first members of ST’s new family, the GANSPIN611 and GANSPIN612, can power motors of up to 400 Watts including domestic and industrial compressors, pumps, fans, and servo drives. Pin compatibility between the two devices ensures designs are easily scalable. GANSPIN611 is in production now, in a 9mm x 9mm thermally enhanced QFN package, from $4.44.

Visitors to SPS - Smart Production Solutions 2025, 25-27 November, at the Nuremberg Exhibition Center, can see the GaNSPIN motor controllers at ST’s booth, no. 271 in Hall 4.

Technical notes on GaNSPIN drivers:

In the new GaNSPIN system-in-package, unlike in general-purpose GaN drivers, the driver controls turn-on and turn-off times in hard switching to relieve stress on the motor windings and minimize electromagnetic noise. The nominal slew rate (dV/dt) of 10V/ns preserves reliability and eases compliance with electromagnetic compatibility (EMC) regulations such as the EU EMC directive. Designers can adjust the turn-on dV/dt of both GaN drivers to fine-tune the switching performance according to the motor characteristics.

With R_DS(on) of just 138mΩ in the GANSPIN611 and 270mΩ in the GANSPIN612, the GaN transistors minimize power dissipation and associated self-heating. This lets power components operate without a heatsink in many applications, thereby reducing the bill of materials, while also reducing circuit footprint by up to 60% to permit a smaller, lower-cost PCB.

 Further features include:

• System-in-package with driver and half-bridge power stage with latest-generation 650V GaN power transistors for driving 3-phase BLDC motors
• Integrated bootstrap diode for high-side circuitry
• Suitable for universal 110V - 230V AC offline-powered appliances
• Fault-sensing comparator for smart shutdown provides fast-acting overcurrent protection with programmable disable time
• Undervoltage lockout (UVLO), overvoltage, overcurrent, thermal, and interlocking protection
• Wide supply and input-voltage range up to 20V, for robust and easy conversion of traditional power stages
• Standby pin for power saving
