DRV8886ATRHRR

Overview

The DRV8886ATRHRR is a bipolar stepper motor driver from Texas Instruments, housed in a 28-WQFN package. It supports a supply voltage range of 8 V to 37 V and delivers an output current of 2 A per bridge. The device integrates two half-bridges with power MOSFETs and operates within a temperature range of -40°C to +125°C. It features a 100 kHz switching frequency and draws 5 mA in operating mode.

Feature Summary

• Fully integrated control and power stage for bipolar stepper motors
• Integrated current sense capability for precise motor control
• Supports microstepping resolutions from full step to 1/16

Applications

• Industrial automation systems
• Consumer electronics requiring precise motion control
• Office automation equipment

Procurement Notes

Verify the specific suffix RHRR confirms the reel packaging format required for automated assembly processes. Confirm that the AT grade designation aligns with the intended thermal performance specifications for the target application environment. Ensure compatibility with the 28-WQFN footprint during PCB layout finalization.

Selection Notes

Select this component when a compact solution for bipolar stepper motors is required with integrated sensing. The WQFN package suits space-constrained designs. Verify that the 2 A current rating meets load requirements without excessive heat sinking. Consider the 1/16 microstepping capability for smooth operation needs.

Part Context

This part belongs to the DRV8886 family of stepper motor drivers. It shares core functionality with variants like DRV8886PWPR but differs in package type. The family provides a complete drive solution for bipolar stepper motors, integrating logic, control, and power stages into a single IC.

Replacement Considerations

DRV8886ATRHRT is a tape-and-reel alternative within the same series. DRV8886RHRR serves as a parameter-equivalent substitute with identical electrical characteristics.
