STMicro Expands GANSPIN Motor Driver Family
STMicroelectronics adds three 100V GaN motor drivers to its GANSPIN lineup, with availability planned by the end of 2026.
Updated on Nov. 10, 2026 in Semiconductors
STMicroelectronics announced three new 100V gallium nitride (GaN) motor drivers, the GANSPIN1102, GANSPIN1102E and GANSPIN1105, expanding its GANSPIN family. The company plans to make the devices available by the end of 2026.
Why it matters
The devices are designed to deliver higher power density, improved efficiency and more compact motor-control systems. Integrating GaN transistors and gate drivers into a single package reduces the number of external components engineers must source and place.
The GANSPIN1100 series supports continuous output currents of up to 60A and switching frequencies up to 5MHz, with a 20ns propagation delay and 1ns delay matching in a 5mm x 6.5mm package. Pricing and exact availability dates remain unconfirmed beyond the end-of-2026 target.
The players
STMicroelectronics
STMicroelectronics is a global semiconductor manufacturer headquartered in Geneva, Switzerland, known for power and motor-control chips used across automotive and industrial applications.
The details
Each driver integrates two GaN transistors, gate drivers with optimized gate resistance, and VCC and bootstrap capacitors, along with smart shoot-through protection that monitors gate-drive output voltage. The devices are supplied in a 1.12mm-high land grid array package and support junction temperatures from -40°C to 125°C.
Timeline
November 9, 2026: New GANSPIN1100 series announced in Geneva
November 10-13, 2026: Demonstration at electronica 2026 in Munich
End of 2026: Planned availability of GANSPIN1100 series devices
The Tech Race
The GANSPIN1100 series extends the move from discrete silicon power stages toward integrated gallium nitride drivers in motor control. It positions STMicroelectronics to compete with other suppliers of GaN power devices for industrial and automotive motor designs.
Engineers designing motor-control systems can reduce external component counts with integrated GaN drivers, potentially simplifying board layout. End users may see more compact and efficient motor-driven products once designs using these devices reach market.
The takeaway
Integrated GaN motor drivers show how power electronics are moving toward smaller packages and fewer discrete parts. Designers evaluating motor-control options should weigh on-resistance, switching frequency and cooling options against their thermal budget.
What happens next
STMicroelectronics plans to make the GANSPIN1102, GANSPIN1102E and GANSPIN1105 available by the end of 2026, with demonstrations at electronica 2026 in Munich from November 10 to 13.
