DRV8256EPWPR

Overview

The DRV8256EPWPR is a Texas Instruments brushed DC motor driver featuring an H-bridge configuration. It supports a supply voltage range of 4.5 V to 48 V and delivers an output current of 8 A. The device operates within a temperature range of -40°C to +125°C and utilizes an HTSSOP-28 package. Quiescent current is specified at 4 mA. This component is classified under Motor / Motion / Ignition Controllers & Drivers.

Feature Summary

• Integrates an H-bridge architecture for dual brushed DC motor control or single bipolar stepper operation.
• Features integrated current sensing capabilities to simplify external circuit design.
• Supports wide operating voltage ranges suitable for various automotive and industrial power supplies.

Applications

• Brushed DC motor control in automotive systems
• Bipolar stepper motor driving applications
• Industrial motion control modules

Procurement Notes

Verify the specific suffix EPWPR corresponds to the HTSSOP-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management solutions are adequate for sustained 8 A operation, as performance depends on PCB layout and ambient conditions. Cross-reference with the latest datasheet revision for any pinout or electrical characteristic updates.

Selection Notes

Select this component for designs requiring high current drive in a compact surface-mount package. The integrated current sensing reduces bill-of-materials count compared to discrete solutions. Consider the HTSSOP-28 thermal pad requirements for heat dissipation. Evaluate the 48 V maximum rating against system transient voltages. Compare quiescent current specifications if low-power standby modes are critical to the application architecture.
