DRV8885PWPR

Overview

The DRV8885PWPR is a stepper motor driver from Texas Instruments designed for industrial equipment applications. It features two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The device supports up to 1.5 A full-scale or 1 A RMS output current at 24 V and TA = 25°C. Operating supply voltage ranges from 8 V to 37 V. It offers PWM microstepping with resolutions from full-step to 1/16 step modes. The component utilizes a simple STEP/DIR interface and includes low-current sleep mode functionality.

Feature Summary

• Integrated current sense functionality eliminates the need for external sense resistors
• Configurable slow and mixed decay options for precise motor control
• Internal protection functions including over-current, short circuit, and thermal shutdown
• Low-power sleep mode provides very-low quiescent current standby capability

Applications

• Industrial equipment motor control
• Printer mechanisms
• Scanner drive systems
• Automation equipment actuation

Procurement Notes

Verify the specific suffix PWPR indicates HTSSOP-28 packaging when ordering. Confirm that the target application requires the 1.5 A full-scale current rating and 8 V to 37 V input range. Ensure PCB ground plane design accommodates thermal dissipation for sustained RMS current operation. Check for compatibility with standard STEP/DIR control logic levels before integration.

Selection Notes

Select this component when integrated current sensing is required to reduce bill of materials count. Choose the DRV8885PWPR for designs needing microstepping capabilities up to 1/16 resolution. Consider this part for applications requiring robust internal fault protection without external monitoring circuits. Evaluate thermal performance requirements against the specified 1 A RMS limit under expected operating conditions.

Part Context

This part belongs to the DRV8885 family of stepper motor drivers manufactured by Texas Instruments. The family focuses on providing high-performance motion control solutions with simplified external component requirements. The PWPR suffix specifically denotes the tape and reel packaging format suitable for automated surface-mount assembly processes in high-volume production environments.

Replacement Considerations

DRV8885PWP: Same functional specifications but in tube packaging instead of tape and reel.
