DRV8825PWP

Overview

The DRV8825PWP is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It operates within a supply voltage range of 8.2 V to 45 V and delivers an output current of up to 2.5 A per phase under appropriate thermal conditions. The device integrates two H-bridge drivers with N-channel power MOSFETs and includes an on-chip microstepping indexer supporting resolutions from full step to 1/32 step. Key electrical parameters include a maximum operating temperature of 150°C junction temperature and a typical switching frequency of 30 kHz.

Feature Summary

• Integrates a microstepping indexer allowing configurable resolution from full step to 1/32 step for smooth motion control.
• Features configurable decay modes enabling selection between slow, fast, or mixed decay settings for optimized motor performance.
• Includes comprehensive protection mechanisms such as overcurrent protection, short-circuit detection, undervoltage lockout, and thermal shutdown.
• Provides a low-power sleep mode accessible via the nSLEEP pin to minimize static current consumption when inactive.

Applications

• Printers and scanners
• Automation equipment
• Medical imaging systems

Procurement Notes

Verify the specific suffix PWP indicates tube packaging rather than reel formats like PWPR. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for any product change notices regarding pin marking or assembly source updates that may affect long-term availability.

Selection Notes

Select this component for applications requiring integrated microstepping control without external logic. Ensure adequate thermal management is designed for the HTSSOP package given the 2.5 A current capability. Verify that the 8.2 V minimum supply voltage aligns with the system power architecture.

Part Context

This part belongs to the DRV8825 family of bipolar stepper motor drivers from Texas Instruments. It serves as a complete solution combining power stages and control logic. The PWP variant specifically denotes the surface-mount HTSSOP-28 package configuration suitable for automated PCB assembly processes.

Replacement Considerations

Direct substitutes include other DRV8825 variants such as DRV8825PWPR for different packaging needs. Cross-family replacements require verification of current ratings and microstepping support compatibility.
