DRV8886ATPWP

Overview

The DRV8886ATPWP is a bipolar stepper motor driver from Texas Instruments, housed in a 24-pin HTSSOP package. It supports an operating supply voltage range of 8 V to 37 V and delivers up to 2 A output current per half-bridge. The device integrates power MOSFETs and logic control for full integration. It operates within a junction temperature range of -40°C to +150°C and features a quiescent supply current of 5 mA. The component includes integrated current sense capabilities and supports step resolutions from 1 to 1/16.

Feature Summary

• Integrates full control and power stages for bipolar stepper motors
• Includes built-in current sensing functionality
• Supports variable step resolutions ranging from full step to 1/16 microstepping

Applications

• Bipolar stepper motor control systems
• General motion control applications
• Industrial automation equipment

Procurement Notes

Verify the specific suffix 'TPWP' corresponds to the tube packaging variant. Confirm that the 'A' grade designation meets required performance specifications. Check for End-of-Life status as indicated by manufacturer notices. Ensure compatibility with the 24-HTSSOP footprint during PCB design review.

Selection Notes

Select this part for designs requiring integrated power and control in a compact surface-mount package. Verify that the 37 V maximum load voltage and 2 A current limits suit the motor requirements. Consider the thermal performance of the HTSSOP-24 package for the intended operating environment.

Part Context

This component belongs to the DRV8886 family of stepper motor drivers. It shares core electrical characteristics with other variants like the DRV8886PWPR but differs in packaging and manufacturing lot details. The 'AT' prefix typically denotes automotive-grade qualification or specific temperature ranges within the product line.

Replacement Considerations

DRV8886ATPWPR is listed as a substitute option.
