DRV8884RHRR

Overview

The DRV8884RHRR is a bipolar stepper motor driver from Texas Instruments, housed in a 28-pin WQFN package. It supports a load voltage range of 8 V to 37 V and delivers an output current of 1 A. The device operates with a supply voltage between 8 V and 37 V and features a maximum operating frequency of 100 kHz. It functions within a temperature range of -40°C to +125°C and draws a typical quiescent current of 5 mA.

Feature Summary

• Integrates current sensing for precise motor control
• Supports microstepping resolutions from full step to 1/16
• Combines logic control and power stages in a single IC

Applications

• Bipolar stepper motor drive systems
• Motion control applications requiring integrated sensing
• Industrial automation equipment

Procurement Notes

Verify the specific suffix RHRR corresponds to the 28-pin WQFN package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the ordering part number matches the exact thermal and electrical specifications required for the target application environment.

Selection Notes

Select this component when a 1-A bipolar stepper driver with integrated current sense is required. The WQFN-28 package suits space-constrained designs. Verify that the 8 V to 37 V load voltage range aligns with the motor supply. Consider the 100 kHz operating frequency limit for high-speed stepping requirements.

Part Context
