DRV8825 Stepper Motor Driver

The DRV8825 Stepper Motor Driver is a high-performance microstepping driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full, half, quarter, eighth, and sixteenth-step modes, with an output drive capacity of up to 45 V and ±2.5 A.

Key Features:

• Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates.
• Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay).
• Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.
• Short-to-ground and shorted-load protection.

Technical Specifications:

• Motor voltage: 8.2 - 45 V
• Logic voltage: 3 - 5.5 V
• Continuous current per phase: 1.5 A
• Maximum current per phase: 2.5 A
• Microstep resolutions: full, half, quarter, eighth, and sixteenth

Possible Applications:

• ATM machines
• 3D printers
• Stage lighting instruments
• Engraving machines
• CNC machines
