STMicroelectronics Stepper Motor Drivers
STMicroelectronics Stepper Motor Drivers are a portfolio of STSPIN stepper motor drivers spanning relatively simple ICs to more complex solutions, like solutions that need to drive a stepper motor using high-level motion commands autonomously. These commands come from the motor or motion control system host, such as a microcontroller, DSP, or FPGA. STSPIN stepper motor drivers provide a ready-to-use solution for motor and motion control systems in various voltage and current ratings. The STMicroelectronics drivers are available in many space-saving, thermally-enhanced packages.
ST also offers a system-in-package (powerSTEP01) integrating the control circuitry and a complete power stage (8 N-channel 16mOhm MOSFETs). This QFN package is for compact, high-power stepper motor applications (85V and 10A).
The STSPIN portfolio comes with low-cost evaluation hardware, software, and a technical documentation toolbox to help minimize time to market.
Features
- Extreme position accuracy and motion smoothness with up to 1/256 micro-steps per full step
- Integration of the PWM control and the power stage made by 500mΩ RDS(ON) MOSFETs guarantees one of the best performance-cost trade-offs
- Easy step-clock and direction interface
- 7 to 45V operating voltage for a wide range of applications
- UVLO, over-current, and thermal protection maximum reliability
- Compact 4mm x 4mm QFN makes it the smallest integrated micro-stepping driver with these ratings
