DRV8832QDGQRQ1

Overview

The DRV8832QDGQRQ1 is an automotive-grade, low-voltage motor driver IC manufactured by Texas Instruments. It features a dual half-bridge output configuration capable of delivering up to 1 A continuous current per channel. The device operates within a supply voltage range of 2.75 V to 6.8 V and supports both brushed DC and bipolar stepper motors. Designed for harsh environments, it functions reliably across a junction temperature range of -40°C to +150°C. The component integrates control logic and power MOSFETs in a compact 10-VSSOP package with exposed thermal pad.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards for long-term durability
• Integrated dual half-bridge architecture enabling bidirectional drive for two motors or one stepper
• Low quiescent current operation to extend battery life in portable applications
• Built-in protection mechanisms including overcurrent shutdown and thermal regulation

Applications

• Battery-powered automotive subsystems requiring robust motor control
• Small brushed DC motor drives in vehicle interior modules
• Bipolar stepper motor actuation in automotive sensors or valves
• Industrial automation components operating under strict temperature constraints

Procurement Notes

Verify the specific suffix 'QDGQRQ1' against official Texas Instruments documentation to confirm the reel packaging variant and automotive qualification status. Ensure compatibility with existing PCB footprints for the 10-VSSOP package. Cross-reference the latest datasheet revision to validate any updates to electrical characteristics or recommended operating conditions prior to final procurement.

Selection Notes

Select this component when automotive certification (AEC-Q100) is mandatory for the target application. It is suitable for designs requiring dual independent motor channels or single bipolar stepper control within a low-voltage domain. Consider the thermal performance of the exposed pad design if high ambient temperatures are expected. Verify that the required peak current does not exceed the continuous 1 A rating without adequate heat dissipation strategies.

Part Context

This part belongs to the DRV8832 family of low-voltage motor drivers from Texas Instruments. The 'Q1' suffix indicates automotive qualification, while 'DGQR' specifies the tape-and-reel packaging format and the DGQ VSSOP package type. It serves as a specialized solution for automotive OEMs needing reliable, space-efficient motor control integrated circuits.

Replacement Considerations

The DRV8832DGQR is a non-automotive grade equivalent from the same manufacturer. Verify if the loss of AEC-Q100 qualification impacts the system requirements before substitution.
