DRV8805PWP

Overview

The DRV8805PWP is a unipolar stepper motor driver manufactured by Texas Instruments, housed in a 20-pin SOIC package. It features an integrated power stage with a maximum output current of 1.5 A per channel and supports supply voltages from 8.2 V to 60 V. The device includes four low-side outputs and operates within a temperature range of -40°C to +125°C. Quiescent supply current is specified at 1.6 mA. It utilizes parallel interface control for step and direction inputs.

Feature Summary

• Integrates full H-bridge driver circuitry with internal current regulation
• Supports microstepping resolution via external resistor selection
• Includes thermal shutdown and overcurrent protection mechanisms

Applications

• Unipolar stepper motor control systems
• Industrial automation positioning devices
• Office automation equipment motion control

Procurement Notes

Verify the specific suffix PWP corresponds to the HTSSOP-20 or SOIC-20 package variant as defined in the official datasheet. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure the supplier provides valid traceability documentation matching the manufacturer's part marking standards.

Selection Notes

Select this component when driving unipolar stepper motors requiring up to 1.5 A continuous current. Consider the 60 V maximum supply voltage capability for higher voltage coil applications. Evaluate the thermal performance requirements given the +125°C junction temperature rating and the specific PCB layout constraints associated with the chosen surface-mount package.
