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.

Features

  • Three-phase gate driver:
    • 1 A sink/source current capability
    • VDS monitoring of the power stage MOSFETs
    • Integrated bootstrap diodes
    • I²C accessible configuration and status registers for best application fit
    • Cross-conduction prevention
  • STM32G431 microcontroller:
    • 32-bit Arm® Cortex-M4 MCU+FPU, up to 170 MHz clock frequency
    • CORDIC mathematical hardware accelerator for trigonometric functions
    • 128 kB Flash memory + 32 kB SRAM memory
    • 2x advanced timers for motor control with up to 6 x PWM channels each
    • 8x general purpose timers
    • 2x ADCs 16-bit resolution (up to 19 channels) with 4 Msps conversion rate
    • 4x 12-bit DAC channels
    • 4x ultra-fast rail-to-rail comparators
    • 3x rail-to-rail operational amplifiers usable also in PGA mode
    • Internal high precision voltage reference
    • Up to 40 GPIOs
    • Full set of interfaces: I²C, SPI, UART, and CAN
  • Self-supplied thanks to embedded flexible power management
    • VCC buck with up to 200 mA and programmable output and embedded MOSFET
    • 3.3 V LDO linear regulator up to 150 mA
    • Low quiescent linear regulator for MCU supply during standby
    • Full set of protections: thermal shutdown, short-circuit, and overload protection
