DRV8462DDWR

Overview

The DRV8462DDWR is a dual H-bridge stepper motor driver from Texas Instruments, housed in a 44-pin HTSSOP package. It supports a supply voltage range of 4.5 V to 65 V and delivers an output current of 8 A per bridge. The device integrates MOSFETs with low on-resistance to minimize power loss. Key features include an internal microstepping indexer supporting up to 1/256 resolution, automatic microstepping interpolation, and sensorless stall detection. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a programmable microstepping indexer with automatic interpolation to reduce controller overhead.
• Features sensorless stall detection to eliminate the need for mechanical end-stop switches.
• Includes intelligent tuning and hybrid decay modes for optimized motor performance.
• Provides comprehensive protection mechanisms including overcurrent, thermal shutdown, and undervoltage lockout.

Applications

• Factory automation systems
• Robotics and motion control
• Medical imaging equipment
• Textile machinery

Procurement Notes

Verify the specific suffix DDWR corresponds to the HTSSOP-44 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical specifications required by your design.

Selection Notes

Select this component for applications requiring high current drive in a compact surface-mount form factor. It is suitable for designs needing integrated microstepping and diagnostic features without external logic. Consider the thermal dissipation capabilities of the HTSSOP package relative to your expected load currents and ambient temperatures.

Part Context

This part belongs to the DRV8462 family of stepper motor drivers. It shares functional similarities with other devices in the series but offers specific voltage and current ratings suited for higher power applications. The DDWR suffix indicates the specific tape-and-reel packaging variant available for automated manufacturing.

Replacement Considerations

The DRV8461 is a pin-compatible alternative offering lower current capacity. For single H-bridge applications, the DRV8962 provides four half-bridges. Verify pin-to-pin compatibility and electrical parameter alignment before substituting these parts.
