Description

This discrete MOSFET stepper motor driver enables 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 configuration of the 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 that can be used for more advanced control and stall detection algorithms. Additional features include reverse-voltage, under-voltage, and over-current protection. 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.
Note: For more technical data kindly refer attached datasheet

Features:

Wide 8?V to 50?V operating voltage range
Nine different step resolutions down to 256 micro steps: 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 micro stepping
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

Package Includes:
1 x Pololu High-Power Stepper Motor Driver 36v4
