    DRV8825PWP schematic symbol

    Motors are one of the most commonly used electrical devices in the world. They are commonly used in all types of industrial, commercial and consumer electronic applications. In fact, the second industrial revolution was kick started due to the invention of motors and electrical machines. There are many different types of motors such as induction motors, synchronous motors, BLDC motors, servo motors and stepper motors. The stepper motors are very widely used in robotics and automatic machinery. In a stepper motor based system, the control circuit of the motor is of great importance. Without efficient and accurate control, the motor cannot deliver the required performance. The motor driver ICs are commonly used to control the power circuit of the motors. The motor driver ICs simplify the control circuit and provide control signals for driving the motor.

    What is DRV8825PWP?

    The DRV8825PWP is an integrated motor driver circuit developed by Texas Instruments. The device features two H-bridge drivers and a micro-stepping indexer. This drive is meant for the bipolar stepper motors. The output driver block consists of N-channel power MOSFETs configured as full H-bridges to drive the stepper motor. Each output of the driver is capable of driving 2.5A current. Proper heat sinking is required with the device to avoid overheating. The presence of a simple STEP/DIR interface makes the interfacing with control circuits quite easy. The motor can be configured for full step to 1/32 step modes. Configurable decay mode allows for slow decay, fast decay and mixed decay. The device also features a low power sleep mode for low power consumption. The device also features protection features like over current, short circuit, over temperature, and under voltage lockout.
