Pololu High-Power Stepper Motor Driver 36v4

Description

Pololu High-Power Stepper Motor Driver 36v4 is a stepper motor driver module based on the DRV8711 chip from Texas Instruments. The module is equipped with external MOSFET which allows control of the bipolar stepper motor with a voltage in the range of 8-50 V and a continuous current of 4 A. The controller allows you to control the motor movement with up to 9 different resolutions. The controller is configured via the SPI interface.

The controller also provides EMF feedback that can be used for more advanced control and stall detection algorithms. Additional features include back-voltage protection, undervoltage and overload protection.

General typical wiring diagram

Features

• Wide 8 V to 50 V operating voltage range
• High-power: can deliver up to 4 A continuous per phase without extra cooling (6 A max with sufficient additional cooling)
• Highly configurable through SPI interface
• Optional STEP/DIR control pins (stepping can also be controlled through SPI interface alone)
• Nine different step resolutions down to 256 microsteps: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, 1/128-step, and 1/256-step
• Adjustable current control lets you set the maximum current output, enabling the use of voltages above your stepper motor’s rated voltage to achieve higher step rates
• Adaptive blanking time, adjustable decay times, and various current decay modes enable the creation of ultra-smooth motion profiles through the SPI interface
• Optional STALL output enables stall detection when microstepping
• Optional BEMF output enables more advanced control and stall detection algorithms based on the back EMF of the stepper motor
• Driver supports alternate operating mode for controlling two brushed DC motors with PWM inputs instead of one bipolar stepper motor with STEP/DIR inputs
• Inputs compatible with 1.8 V, 3.3 V, and 5 V logic
• Digital outputs are all open drain with pull-ups to externally supplied IOREF voltage for use with non-5V systems (IOREF can be connected to neighboring 5V OUT pin for use with 5V systems)
• Under-voltage lockout, over-current protection, short circuit protection, and reverse-voltage protection (up to 40 V)
• Arduino library and example sketches are available that provide basic functions for configuring and operating the driver
