ST’s STSPIN drivers for 3-phase brushless DC (BLDC) motors includes power drivers in a 3-phase bridge configuration and integrated solutions with built-in decoding logic for Hall-effect sensors and a PWM current controller to autonomously drive a BLDC motor through motion commands coming from the motor or motion control system host – a microcontroller, DSP or FPGA.

In addition to the integration of the power MOSFET and the associated driving circuitry, they include protection and diagnostic features for over-temperature, over-current and under-voltage conditions, resulting in robust and reliable designs.

Available in a wide selection of space-saving, thermally-enhanced packages, STSPIN 3-phase BLDC motor driver ICs provide a ready-to-use and optimized solution for motor and motion control systems in a wide range of voltage and current ratings.

Turnkey motor control modules that provide all the functions required such as speed, position and current loop execution and real-time connectivity to the master, are also available. With their compactness, these modules are ideal for direct installation on a permanent magnet synchronous motor (PMSM).

The STSPIN portfolio comes with extensive evaluation hardware and software as well as a technical documentation toolbox to help minimize time to market.

The benefit of our 10 and 15 years longevity program is available for our industrial grade STSPIN motor drivers.

32-bit MCU-based BLDC motor drivers in tiny 7x7 mm QFN

The STSPIN32F0 and STSPIN32F0A combine a 32-bit ARM ® Cortex ®-M0 core STM32F0 microcontroller and a three-phase, half-bridge gate driver in a tiny 7x7 mm QFN package, delivering the flexibility and power of a microcontroller-based drive with the convenience, simplicity and space-efficiency of a single IC. Ideal for BLDC motors in applications up to 45 V, they greatly simplify design challenges by leveraging the extensive STM32 development ecosystem with software tools, firmware libraries and middleware available on top of the popular motion-control algorithms such as Field-Oriented Control (FOC) and 6-step sensored / sensorless control to streamline firmware development. The new STSPIN32F0A can operate from a supply voltage as low as 6.7 V, which is equivalent to two LiPo cells, making it ideal for battery-powered applications.
