DRV8871DDARQ1

Overview

The DRV8871DDARQ1 is an automotive-grade H-bridge motor driver designed for brushed DC and stepper motors. It features a supply voltage range of 6.5 V to 45 V and delivers up to 3.6 A output current. The device integrates current sensing and regulation, eliminating the need for external sense resistors. It operates within a temperature range of -40°C to +125°C and utilizes an 8-SO PowerPAD package. Key electrical parameters include a maximum load voltage of 45 V, a minimum operating voltage of 6.8 V, and a quiescent current of 3 mA.

Feature Summary

• Integrated current sensing and regulation circuitry without requiring external sense resistors
• Advanced protection mechanisms including overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lockout (UVLO)
• Automatic recovery from fault conditions upon removal of the fault state
• Low-power sleep mode activated by setting both logic inputs to a low state

Applications

• Automotive systems requiring AEC-Q100 qualified components
• Printers and office automation equipment
• Home appliances with motor control requirements
• Industrial machinery and small electromechanical devices

Procurement Notes

Verify that the specific part number suffix matches the required automotive qualification standards. Confirm the package type corresponds to the design footprint. Ensure the supplier provides valid traceability documentation. Check for moisture sensitivity level compliance during storage and handling. Validate that the component batch meets the specified operational temperature range requirements.

Selection Notes

Select this component when an automotive-rated H-bridge driver is necessary for brushed DC or unipolar stepper motors. It is suitable for applications demanding integrated current management to simplify PCB layout. Consider this device for designs requiring robust fault protection and automatic recovery features. It is appropriate for systems operating within the specified voltage and temperature constraints.

Part Context

This component belongs to the DRV8871 family of motor drivers manufactured by Texas Instruments. It is specifically engineered for automotive environments, distinguishing it from non-automotive variants through its qualification status. The device serves as a compact solution for controlling high-current loads in space-constrained electronic assemblies.

Replacement Considerations

The DRV8871DDAR is the non-automotive equivalent of this component. Verify if automotive qualification is strictly required before substituting with non-Q1 versions.
