DRV8880PWPR

Overview

The DRV8880PWPR is a fully integrated bipolar stepper motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 6.5 V to 45 V and delivers an output current of 2 A. The device utilizes a 28-pin HTSSOP package with a maximum junction temperature rating of 150°C. It supports multiple microstepping resolutions including full, half, quarter, eighth, and sixteenth step modes. The component features logic interface control and power MOSFET technology for efficient motor management.

Feature Summary

• Integrates all necessary control logic and power stages into a single compact solution
• Supports variable microstepping resolution from full step to 1/16 step for smooth motion control
• Includes built-in protection mechanisms against overcurrent, undervoltage, and thermal overload conditions

Applications

• Bipolar stepper motor control in industrial automation systems
• Motion control modules for office automation equipment
• Precision positioning drives in medical devices

Procurement Notes

Verify the specific suffix PWPR corresponds to the HTSSOP-28 tape and reel packaging configuration. Confirm that the operating environment remains within the specified -40°C to 150°C junction temperature limits. Ensure input voltage does not exceed the 45 V maximum rating during transient events. Check for RoHS3 compliance requirements if applicable to your assembly process.

Selection Notes

Select this component when a high-voltage bipolar stepper driver with integrated logic is required. It is suitable for applications needing up to 2 A continuous current without external heat sinks under moderate loads. Consider the 28-pin footprint for PCB layout constraints. Evaluate thermal dissipation capabilities based on ambient temperature and enclosure design before finalizing the design.

Part Context

This part belongs to the DRV8880 family of stepper motor drivers designed for space-constrained applications. It replaces discrete solutions by combining gate drivers, current sources, and protection circuits. The HTSSOP package offers improved thermal performance compared to smaller footprints while maintaining compatibility with standard surface mount assembly processes.

Replacement Considerations

Direct pin-to-pin replacements may include other variants within the DRV888x series such as DRV8881 or DRV8884, provided current ratings and voltage specifications match the application requirements. Verify package compatibility and electrical characteristics before substitution.
