电机驱动器  

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.

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 years 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.

A wide range of evaluation boards is provided, together with low-cost plug-and-play discovery kits: an ideal development tool for both beginners and experienced users that is autonomous and can be used with a software interface or with a custom firmware thanks to the embedded microcontroller.

Schematics, BOMs and gerber files are available to give you a headstart with your hardware design together with comprehensive technical documentation.
Software suites are also provided to enable quick and easy development of motor driving solutions.

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.

The comprehensive development environment includes:

STM32 Nucleo development boards: 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.

Boost the runtime of battery-powered IoT devices

Low-voltage monolithic motor drivers

ST has extended its portfolio of STSPIN motor drivers with the introduction of four new monolithic devices that simplify design, save space and are optimized for battery-powered stepper ( STSPIN220, with a position resolution of 256 microsteps per full step), 3-phase brushless motors ( STSPIN230), dual DC brushed ( STSPIN240) and single DC brushed ( STSPIN250) motors in portable applications.
They operate from a supply voltage as low as 1.8 V, over a wide current and temperature range, and can be forced in a zero consumption state (with quiescent current less than 80 nA), which allows significant power savings for extended runtime of battery-powered IoT devices. Available in a 3 x 3 mm QFN package, they benefit from comprehensive built-in protection features including over-current, over-temperature and short-circuit for high ruggedness and reliability even in harsh industrial environments.
