STSPIN32G4 – High performance 3-phase motor controller with embedded STM32G4 MCU


STMicroelectronics’ high-performance 3-phase motor controller features an unprecedented level of integration and flexibility.

STMicroelectronics’ STSPIN32G4 is a high-performance 3-phase motor controller featuring an unprecedented level of integration and flexibility. It packs a complete motion control system in a single package. It is among very few products on the market that integrate a very high-performance Cortex®-M4 MCU (STM32G431) with 75 V / 1 A rated 3-phase gate driver and flexible power management regulators, all in a thermally efficient 9×9 QFN package.

It is designed to efficiently address a wide range of applications such as cordless power and garden tools, servo drives, e-bikes, robotic arms, home appliances (vacuum cleaners, dryers, and cleaning robots), pumps, fans, and many others.
