drv8825 datasheet

The DRV8825 is a versatile, high-performance stepper motor driver that offers precise control and efficient operation for various applications. This compact and easy-to-use driver is designed by Texas Instruments and integrates a DMOS full-bridge motor driver with a flexible current regulation capability. The DRV8825 features a maximum current rating of 2.5A per coil, allowing it to handle a wide range of stepper motors. Its built-in translator eliminates the need for external phase sequencers, simplifying the design process. This driver is compatible with a variety of control signals, including step, direction, and enable inputs. The DRV8825’s high-resolution microstepping capability enables smoother and more accurate motion control. It supports up to 1/32 microstepping, providing finer positioning and reduced noise and vibration. It also features an adjustable current limiting function, allowing users to optimize motor performance while protecting the driver and motor from overcurrent conditions. With its robust design, advanced features, and compatibility with various stepper motors, the DRV8825 is an ideal choice for applications such as 3D printers, CNC machines, robotics, and automation systems.
