The DRV8825 is a microstepping bipolar stepper motor driver IC manufactured by Texas Instruments. The DRV8825 offers a wide operating voltage range of 8.2V to 45V and can deliver up to 2.5A of current per phase to drive a stepper motor, making it suitable for a variety of motion control applications. The device utilizes a chopper drive architecture to efficiently regulate the current in each winding of the stepper motor, resulting in improved performance and reduced power dissipation. The DRV8825 supports multiple microstepping resolutions, allowing for finer control over the stepper motor's movement. The device also features built-in protection functionalities such as overcurrent, overtemperature, and undervoltage lockout to ensure safe and reliable operation. The DRV8825 datasheet provides detailed information on the device's electrical characteristics, pinout, application circuit examples, and recommended operating conditions, making it a valuable resource for engineers designing stepper motor control systems.
