Pololu High-Power Stepper Motor Driver 36v4

Pololu High-Power Stepper Motor Driver 36v4

Control one bipolar stepper motor with wide voltage range and advanced features.

• Operating Voltage: 8V to 50V
• Continuous Current per Phase: 4A (6A max with cooling)
• Step Modes: 9 modes from full-step to 1/256-step
• Interface: SPI for configuration
• Protection: Reverse-voltage, under-voltage, over-current
• Features:
  • Wide voltage range
  • Nine step resolutions
  • Adjustable current control
  • Stall detection

This discrete MOSFET stepper motor driver enables precise control of one bipolar stepper motor. It supports a wide 8 V to 50 V operating voltage range and can deliver up to 4 A continuous per phase without a heat sink or forced air flow (6 A max with sufficient additional cooling).

The SPI interface allows easy configuration of current limiting, step mode (9 step modes from full-step through 1/256-step), decay mode, and stall detection. The driver also provides back-EMF feedback for advanced control and stall detection algorithms.

Additional features include reverse-voltage, under-voltage, and over-current protection for added safety during operation.

The Pololu High-Power Stepper Motor Driver 36v4 combines the DRV8711 stepper motor driver IC from Texas Instruments with external MOSFETs to enable control of large bipolar stepper motors at operating voltages from 8 V to 50 V.
