STMicroelectronics Low-Voltage STSPIN Motor Drivers

STMicroelectronics’ STSPIN32F0 is a system-in-package that reduces the number of components and design complexity for driving three-phase BLDC motors. It includes an advanced BLDC controller that integrates 3 half-bridge gate drivers for power MOSFETs or IGBTs, with bootstrap diodes and an interlock that prevents cross-conduction.  It also includes a fully featured STM32 MCU with an ARM Cortex-M0 core to perform FOC, 6-step sensorless, speed control loops, and other advanced driving algorithms.  The STSPIN32F0 can operate from an 8 to 45 V supply and includes a 12 V linear regulator for the gate drivers and a 3.3 V switching regulator to supply the MCU and external components if needed.  It’s versatility makes it ideal for consumer and industrial motor drive applications.

  • Gate drivers: Three-phase (3x half-bridge)
    • 600 mA sink/source
  • STM32 MCU: ARM Cortex-M0 core
    • GPIOs, timers, ADC, serial interfaces
  • 3.3 V Regulator: 70 mA output current
    • Can be used to power external components
  • Extended Temperature Range: -40°C to +125°C
