TIDRV8825PWPR
Overview
The DRV8825PWPR is a high-performance bipolar stepper motor driver designed to operate from 8.2V to 45V. It integrates two H-bridge drivers and a microstepping indexer capable of driving up to 2.5A of output current. The device features a simple STEP/DIR interface, significantly reducing the overhead on the controlling microcontroller.
Why Choose This Part
The DRV8825PWPR supports 1/32 microstepping for smoother motion and reduced resonance compared to standard drivers. It includes built-in protection features such as overcurrent, thermal shutdown, and undervoltage lockout, which increase system reliability. The HTSSOP package with an exposed thermal pad ensures efficient heat dissipation during high-current operation.
Applications
Key Specifications
Getting Started
To begin development, connect the STEP and DIR pins to any logic-level MCU output and provide a motor supply between 8.2V and 45V to the VM pin. Use the internal 3.3V reference or an external voltage to set the current limit via the VREF pin to protect your motor. Evaluation can be simplified using the DRV8825EVM hardware module.
