GaNSPIN GaN motor drivers for compact, efficient motion control

ST’s GaNSPIN family integrates GaN power transistors and gate drivers in a single compact package, helping designers build smaller, cooler and more efficient motor drives. The family now covers two voltage classes: 100 V devices for battery-powered robotics and e-mobility, and 650 V devices for mains-powered appliances and factory automation.

100 V GaN motor drivers for 48 V and 60 V battery systems

Humanoid robot with connected network lines The GANSPIN1102, GANSPIN1102E and GANSPIN1105 are 100 V GaN half-bridge motor drivers in a 5 mm x 6.5 mm LGA package. Each integrates two enhancement-mode GaN transistors, a gate driver with optimized gate resistors, VCC and bootstrap capacitors and a dynamic bootstrap switch. They are designed for space-constrained motor control in humanoid robot joints, robotic arms, e-bikes, drones, power tools and factory automation.

Key benefits of 100 V GaNSPIN GaN motor drivers:

Compact, integrated half-bridge: two GaN FETs, driver, gate resistors and supply capacitors in one 5 mm x 6.5 mm package reduce bill of materials and board area. The optimized pinout supports good performance on a two-layer PCB.
High efficiency and precise timing: 20 ns propagation delay, 1 ns delay matching and smart shoot-through protection allow near-zero dead time and switching frequencies up to 5 MHz.
Tunable EMI and switching speed: separate turn-on and turn-off gate-driver outputs let designers adjust switching speed with external resistors for the best EMI and efficiency trade-off.
Built-in protection: input interlocking, UVLO and OVLO on VCC and bootstrap, thermal shutdown and a dynamic bootstrap switch that prevents bootstrap capacitor overcharge.
Scalable power range: the three devices share one footprint, so one PCB layout can serve different motor power levels.

Applications: humanoid robots and robotic joints, industrial robots and automation, e-bikes, drones, power tools.

650 V GaNSPIN GaN motor drivers for appliances and factory automation

Modern kitchen with stainless steel appliances and white cabinets. ST’s GaNSPIN GaN motor driver family combines 650 V GaN half bridges and high-voltage gate drivers in a single system-in-package, bringing wide-bandgap efficiency to white goods and factory automation.

By precisely controlling switching times, GaNSPIN drivers cut motor stress and EMI, simplify EMC compliance, and enable cooler, smaller designs without heatsinks in many cases.

With low R_DS(on), wide input voltage support, and robust integrated protections, they help designers boost motor performance, shrink PCB size by up to 60%, and meet demanding energy-efficiency standards.

Key benefits of GaNSPIN GaN motor drivers:

System-in-package GaN driver for faster design integrates a 650 V GaN power stage and high-voltage gate driver to simplify layout, cut BoM, and speed design cycles.
Precise switching control and adjustable dV/dt reduce EMI, motor stress, and noise while helping designs meet EMC requirements.
Wide input voltage range for global appliances supports 110 to 230 V AC offline-powered appliances and industrial drives in white goods and factory automation.
Scalable designs with pin compatible devices let designers move from ~300 to >400 W motor power using pin-compatible devices with minimal redesign.

Reference designs and evaluation boards with STM32 MCUs and the ST Motor Control SDK provide ready-to-use 3-phase FOC examples to cut development time and cost. Alongside datasheets, application notes, and software tools, these resources help designers quickly explore GaN performance, derisk their designs, and bring high-efficiency motor drives to market faster.
