DRV8425PRGER

Overview

The DRV8425PRGER is a bipolar stepper motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 35V and delivers an output current capability of up to 2A. The device supports both bipolar stepper and dual brushed DC motor configurations. It features a compact HTQFP-48 package suitable for surface-mount applications.

Feature Summary

• Integrated control logic for bipolar stepper motors
• Supports microstepping resolution down to 1/256 step
• Built-in short-to-ground and over-current protection

Applications

• Bipolar stepper motor control systems
• Dual brushed DC motor drives
• Industrial automation actuators

Procurement Notes

Verify the specific suffix PRGER against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the ordering part number matches the required thermal performance and pinout configuration for your PCB layout. Cross-reference with the manufacturer's latest revision history to avoid obsolete components.

Selection Notes

Select this component when driving bipolar stepper motors requiring up to 2A peak current within a 35V limit. Consider the HTQFP-48 package constraints for thermal dissipation in enclosed spaces. Evaluate the need for high-resolution microstepping capabilities versus simpler full-step requirements for your motion control precision.

Part Context

This part belongs to the DRV84xx family of integrated motor drivers designed for precise motion control. It consolidates power stages, control logic, and protection circuits into a single solution. The series targets applications demanding reliable stepper motor operation with minimal external component count.

Replacement Considerations

Consult the TI DRV84xx family cross-reference guide for verified substitutes. Confirm that alternative parts match the HTQFP-48 footprint and electrical ratings before substitution.
