DRV8886RHRT

Overview

The DRV8886RHRT is a bipolar stepper motor driver from Texas Instruments, featuring an integrated half-bridge architecture with a maximum load voltage of 37 V and an output current capability of 2 A. It operates within a supply voltage range of 8 V to 37 V and supports step resolutions from full step to 1/16 microstepping. The device includes built-in control and power stages, functioning at a switching frequency of 100 kHz. Designed for surface-mount installation in a WQFN-28 package, it ensures reliable operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrated full solution combining logic control and power MOSFET stages for bipolar stepper motors
• Supports multiple step resolutions including full step, half step, quarter step, eighth step, and sixteenth step microstepping
• Built-in protection mechanisms against overcurrent, under-voltage lockout, and thermal shutdown

Applications

• Bipolar stepper motor control in industrial automation systems
• Motion control applications requiring precise positioning
• Office automation equipment such as printers and scanners

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix RHRT corresponds to the required tape-and-reel packaging format. Check for recent product discontinuance notifications, as this part may be subject to end-of-life status. Ensure compliance with RoHS directives and moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when designing circuits for bipolar stepper motors requiring up to 2 A continuous current. It is suitable for applications needing integrated control logic without external drivers. Consider the WQFN-28 package constraints for thermal management and PCB layout. Evaluate if the 37 V maximum voltage rating aligns with the motor supply requirements.

Part Context

This component belongs to the DRV8886 family of stepper motor drivers from Texas Instruments. It shares functional similarities with variants like DRV8886PWPR and DRV8886RHRR but differs in packaging and reel specifications. The family is designed for compact, high-performance motion control solutions.

Replacement Considerations

DRV8886RHRR serves as a parameter-equivalent alternative with identical electrical characteristics but potentially different packaging options.
