DRV8886ATRHRT

Overview

The DRV8886ATRHRT is a bipolar stepper motor driver from Texas Instruments, featuring an integrated current sense amplifier and a 28-pin WQFN package. It supports a supply voltage range of 8 V to 37 V with a maximum output current of 2 A per phase. The device operates within a temperature range of -40°C to +125°C and includes protection features such as overcurrent protection and thermal shutdown.

Feature Summary

• Integrated current sense amplifier for precise current control
• Supports microstepping resolutions from full step to 1/16
• Includes overcurrent protection and thermal shutdown mechanisms

Applications

• Industrial automation systems
• Office equipment
• Security systems

Procurement Notes

Verify the specific suffix RHRT indicates the reel packaging format. Confirm the AT grade specifications against project requirements. Check for End-of-Life notifications or discontinuance notices prior to finalizing procurement decisions.

Selection Notes

Select this component when a compact solution with integrated sensing is required. Ensure the application voltage does not exceed 37 V. Verify that the thermal management design accommodates the WQFN package constraints.

Part Context

This part belongs to the DRV8886 family of stepper motor drivers. It shares core functionality with other variants in the series but differs in packaging and specific electrical characteristics defined by the AT grade and RHRT suffix.

Replacement Considerations

DRV8886ATPWPR is a pin-compatible alternative in a different package. DRV8886RHRR is a similar variant with standard grading.
