DRV8825 Stepper Motor Driver

The DRV8825 Stepper Motor Driver stands as a superior microstepping driver equipped with an inbuilt translator, simplifying its operation. It is engineered to control bipolar stepper motors in various modes, including full, half, quarter, eighth, and sixteenth-step. The driver can handle an output drive capacity reaching up to 45 V and ±2.5 A.

Key Features:

• Adjustable current control feature allows the setting of the maximum current output using a potentiometer. This feature enables the use of voltages higher than your stepper motor's rated voltage to achieve increased step rates.
• Smart chopping control that autonomously chooses the appropriate current decay mode (either fast decay or slow decay).
• Protection features include over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection.
• Additional safety measures include 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

Potential Applications:

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