STSPIN Motor Drivers and Motor Driver Solutions

STMicroelectronics' compact STSPIN motor drivers for low- to mid-power applications

Image of STMicroelectronics' STSPIN Motor Drivers, and Motor Driver SolutionsSTMicroelectronics extends its portfolio of STSPIN monolithic motor drivers with the STSPIN8 series. The STSPIN8 series drivers simplify design solutions and boost motor efficiency thanks to a wide application voltage range, standby mode in idle state, RDS(ON) as low as 500 mΩ, and a full set of integrated protection functions, all in a compact 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

These three monolithic devices simplify design, save space, and are optimized for stepper (STSPIN820, with a position resolution of 256 microsteps per full step), 3-phase brushless motors (STSPIN830), and dual DC brushed (STSPIN840) applications. They operate from a supply voltage from 7 V to 45 V, over a wide current and temperature range, and can be forced in a low consumption state (with standby current consumption down to less 45 µA), which allows significant power savings. Available in a 4 mm x 4 mm QFN package, they benefit from comprehensive built-in protection features including overcurrent, overtemperature, and short-circuit for high ruggedness and reliability even in harsh industrial environments.

Bipolar Stepper Motor Solution
STMicroelectronics offers a complete evaluation package for integrated low voltage motor drives enabling easy exploration of the STSPIN820. X-Nucleo boards for bipolar stepper motors (X-NUCLEO-IHM14A1), together with the NUCLEO-F030R8 board, combined with the X-CUBE-SPN14 expansion package for STM32Cube to give users full control of their low voltage motor.
