DRV8825PWPR

Overview

The DRV8825PWPR is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It operates within an 8.2 V to 45 V supply voltage range and delivers up to 2.5 A output current per phase under specified thermal conditions. The device integrates a microstepping indexer supporting resolutions from full step to 1/32 step. It features a simple Step/Dir interface for controller connectivity and includes programmable decay modes. Internal protection mechanisms cover overcurrent, short circuit, undervoltage lockout, and overtemperature scenarios.

Feature Summary

• Integrates a microstepping indexer with configurable resolution up to 1/32 step
• Features a simple Step/Direction interface for direct controller connection
• Includes programmable decay mode selection for optimized motor performance
• Provides comprehensive internal shutdown functions for system protection

Applications

• Printers and scanners
• Automated equipment
• Financial processing machines
• Video surveillance cameras

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package and reel packaging configuration. Confirm that the component meets RoHS compliance requirements for your target market. Ensure proper thermal management design is implemented, as the rated current capability depends on adequate heatsinking and ambient temperature conditions during operation.

Selection Notes

Select this component when a compact solution for driving bipolar stepper motors is required. It is suitable for applications needing precise positioning through microstepping capabilities. Consider the 2.5 A current rating against the motor's RMS requirements. Evaluate the 8.2 V to 45 V input range compatibility with the system power supply. The integrated indexer simplifies control logic compared to discrete driver solutions.

Part Context

This part belongs to the DRV8825 series of stepper motor drivers from Texas Instruments. It is designed as an integrated solution combining control logic and power stages. The PWPR suffix indicates the specific tape-and-reel packaging variant of the HTSSOP-28 package. It serves as a drop-in replacement for similar legacy drivers in printer and automation designs requiring high microstepping resolution.

Replacement Considerations

The DRV8824PWPR is a related variant offering lower current capacity. Verify pin-to-pin compatibility if substituting with other DRV88xx family members. Ensure that the alternative component supports the required 1/32 microstepping resolution and compatible supply voltage range.
