DRV8886RHRR

Overview

The DRV8886RHRR is a bipolar stepper motor driver from Texas Instruments, housed in a 28-WQFN (5.5x3.5) package. It supports a supply voltage range of 8 V to 37 V and delivers an output current of 2 A per phase. The device operates within a temperature range of -40°C to +125°C and features a half-bridge output configuration with two outputs. It integrates power MOSFET technology and logic interface for control.

Feature Summary

• Fully integrated design combining control logic and power stage
• Supports microstepping resolutions from full step to 1/16
• Integrated current sense capability for precise regulation

Applications

• Bipolar stepper motor control
• General motion control systems
• Industrial automation components

Procurement Notes

Verify the specific suffix RHRR corresponds to the WQFN-28 reel packaging format. Confirm that the 2-A output rating aligns with thermal management requirements for the target application environment. Ensure compatibility with the 8-V to 37-V supply voltage range before integration.

Selection Notes

Select this component when a compact surface-mount solution is required for bipolar stepper applications. The 28-WQFN package offers space efficiency compared to larger footprints. Consider the 2-A current limit and 37-V maximum voltage as primary constraints for system design.

Part Context

This part belongs to the DRV8886 series of stepper motor drivers. It shares functional similarities with other variants like the DRV8886PWPR but differs in package type. The series focuses on integrating control and power stages for efficient motor driving.

Replacement Considerations

The DRV8885RHRR is listed as a parameter-equivalent substitute. Verify pinout and electrical specifications match before substitution.
