STMicroelectronics has extended its GANSPIN family with three new 100-V gallium nitride (GaN) motor drivers designed to simplify the development of compact, high-efficiency motor control systems. The new devices target applications including robotics, industrial automation, e-bikes, drones, and power tools, where high power density and precise control are critical.
The new portfolio includes the GANSPIN1102, with a typical RDS(on) of 2.4 mΩ; the GANSPIN1102E, which adds top-side cooling for improved thermal management; and the GANSPIN1105, with a typical RDS(on) of 5.5 mΩ. All three devices are housed in a compact 5mm × 6.5mm package and integrate two GaN transistors, gate drivers, optimized gate resistance, and supporting power circuitry.
A key advantage of the GANSPIN1100 series is its high integration, which reduces board complexity, minimizes component count, and lowers overall bill-of-materials costs. The devices support optimized layouts on two-layer PCBs, enabling compact motor-drive designs for space-constrained applications.
For robotics and servo-control applications, the drivers provide continuous output currents of up to 60 A, enabling engineers to develop lightweight, highly responsive motion-control systems. High dv/dt immunity, precise timing control, and integrated protection features also contribute to long-term reliability in demanding industrial environments.
The devices feature independent gate-driver outputs for both high-side and low-side transistors, enabling designers to optimize switching behavior for maximum efficiency and reduced electromagnetic interference (EMI). A propagation delay of just 20ns and delay-matching accuracy of 1ns enable switching frequencies up to 5 MHz, supporting advanced motor-control architectures.
Additional features include intelligent shoot-through protection, near-zero dead-time operation to reduce switching losses, dynamic bootstrap control, input interlocking, undervoltage and overvoltage protection, and thermal shutdown. Together, these functions enhance efficiency while protecting the system under a wide range of operating conditions.
The GANSPIN1102, GANSPIN1102E and GANSPIN1105 operate across a junction temperature range of -40°C to 125°C and are supplied in a low-profile 1.12-mm LGA package. Devices are expected to be available by the end of 2026.
At electronica 2026 in Munich, STMicroelectronics will demonstrate the GANSPIN1102E in a robotic arm application, highlighting the technology’s suitability for compact, efficient motion-control systems.
