Pololu 8-50V 4A High-Power Stepper Motor Driver 36v4

• Pololu 8-50V High-Power Stepper Motor Driver 36v4
• Offers a wide operating voltage range of 8 to 50 V
• Can deliver up to 4 A continuous per phase without extra cooling
• Is highly configurable through SPI interface
• Has optional STEP/DIR control pins
• Provides optional STALL output enables stall detection when microstepping

The Pololu 8-50V 4A 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.

The DRV8711 has many configurable settings, so please see the DRV8711 datasheet (3 MB pdf) for a detailed explanation of its features and how to use them.

The driver’s power performance is a function of the external dual H-bridges, which allow the driver to deliver continuous currents up to 4 A per phase without any additional cooling such as heat sinks or forced air flow.
