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
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.
STSPIN motor drivers
Scalable and robust stepper motor drivers, featuring accurate positioning and smooth motion profile with up to 256 micro-steps per step.
Simple, reliable and cost-effective solution to drive one or more brushed DC motors over a wide current and voltage range.
Extensive diagnostics and fully-protected to reduce the number of external components, cost and complexity.
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.
This demonstration presents the use of an intelligent system solution consisting of the STWIN.box, a development kit that simplifies prototyping and testing of advanced industrial sensing applications and the EVLSPIN32G4-ACT, the STSPIN32G4 reference design for next generation smart actuators. The embedded AI algorithm on the STWIN.box detects motor state in real time and sends the results back to the GUI. The user can use the toggle switch to simulate different faults: anomalies from magnet interference or overlapping vibrations.
Simplify cordless power tool development with plug-and-play STSPIN32 reference designs
Use our design prototypes for compact cordless home and garden power tools with low standby current, complete with six-step motor control logic using Hall-effect rotor-position sensing to ensure low torque ripple and very high efficiency.
Compact STSPIN Motor Drivers for Low- to Mid-Power Applications
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:
