ST, a pioneer in the field of motor and motion control, offers a wide range of motor drivers covering the requirements of brushed DC motors, stepper motors and brushless DC motors over an extensive range of voltage and current ratings.

State-of-the-art motor drivers

 

stspin motor drivers

 

Our line-up of STSPIN motor drivers embeds all the functions needed to drive motors efficiently and with the highest accuracy, and include an advanced motion profile generator to relieve the host microcontroller, while ensuring robustness and reliability thanks to a comprehensive set of protection and diagnostic features.

Operating from a supply voltage as low as 1.8 V, the portfolio has been extended with the introduction of low-voltage STSPIN motor drivers which enable power savings in battery-powered smart devices thanks to the best-in-class standby current of less than 80 nA.

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

A complete ecosystem is provided to support design-in and shorten time-to-market

Designing motor control applications becomes much easier with the outstanding performance, features and full support of STSPIN motor driver ICs that make brushed DC, stepper and brushless motor control designs more efficient in a variety of applications.

In addition, STSPIN motor drivers can be easily evaluated in combination with an STM32 32-bit microcontroller in an open, flexible and affordable development environment to enable fast prototyping that can quickly be transformed into final designs. Discover now your STM32 Ecosystem for Motor Control.

The comprehensive development environment includes:

  • STM32 Nucleo development boards with a comprehensive range of affordable development boards for all STM32 microcontroller series.
  • STM32 Nucleo expansion boards based on STSPIN motor drivers, the expansion boards can be plugged on top of the STM32 Nucleo development boards. More complex functionalities can be achieved by stacking additional expansion boards.

The expansion boards are equipped with standardized interconnections such as an Arduino Uno R3 connector or a morpho connector for a higher level of connectivity.
Each expansion board is supported by STM32-based software modules.

Compact STSPIN Motor Drivers for Low- to Mid-Power Applications

STSPIN820-STSPIN830-STSPIN840

ST has extended its portfolio of STSPIN monolithic motor drivers with the introduction of STSPIN8 series, that simplify design solutions and boosts motor efficiency. This is achieved thanks to its wide application range (from 7 to 45 V), its standby mode in idle state, its RDS(ON) as low as 500 mΩ and a full set of integrated protection functions, all in a compact 4 x 4 mm QFN package.

STSPIN8 series includes:

  • STSPIN820: advanced 256-microstep stepper motor driver with step-clock and direction interface
  • STSPIN830: versatile three-phase BLDC motor driver with dedicated Mode input pin
  • STSPIN840: compact dual brushed DC motor driver with dedicated parallel input pin
