DRV8824RHDR

Overview

The DRV8824RHDR is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-VQFN package. It integrates a 1/32 microstepping indexer for precise motion control via step and direction signals. The device supports an output current of 1.6 A with a supply voltage range of 8.2 V to 45 V. Operating temperatures span from -40°C to +85°C, and the quiescent supply current is 5 mA.

Feature Summary

• Integrates an on-chip 1/32 microstepping indexer for high-resolution positioning
• Accepts simple step and direction input signals for easy interface
• Includes built-in blank time filter to accommodate high-current applications

Applications

• Bipolar stepper motor control systems
• Precision motion control applications requiring microstepping
• Industrial automation equipment

Procurement Notes

Verify the specific suffix RHDR corresponds to the 28-VQFN (5x5) package variant. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the ordering information matches the exact pinout and thermal pad configuration documented in the official datasheet.

Selection Notes

Select this component when bipolar stepper motor control with integrated microstepping is required. The 1.6 A output rating suits moderate load applications. Verify that the 8.2 V to 45 V supply range aligns with your system power architecture. Consider the 28-VQFN package for space-constrained designs requiring surface mount installation.

Part Context

This part belongs to the DRV8824 family of stepper motor drivers from Texas Instruments. It is designed as a complete solution for driving bipolar stepper motors, combining logic control and power stages in a single compact package. The family emphasizes ease of use through simple digital interfaces and integrated protection features.

Replacement Considerations

DRV8824PWPR is a verified alternative offering identical functionality in an HTSSOP-28 package.
