DRV8823QDCARQ1

Overview

The DRV8823QDCARQ1 is an automotive-grade stepper motor driver from Texas Instruments, designed for high-reliability applications. It features a quad half-bridge output configuration capable of driving bipolar stepper motors or two brushed DC motors. The device operates within a supply voltage range of 8 V to 32 V and delivers up to 1 A of output current per channel. It is qualified under the AEC-Q100 standard and functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a compact HTSSOP-48 package suitable for surface-mount assembly.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for enhanced reliability
• Quad half-bridge architecture supporting dual bipolar stepper or dual brushed DC motor control
• Integrated thermal shutdown protection to safeguard against overheating conditions

Applications

• Automotive infotainment systems requiring precise actuator control
• Vehicle climate control modules utilizing stepper-driven valves or dampers
• Power seat adjustment mechanisms in automotive interiors

Procurement Notes

Verify that the specific part number suffix matches the required automotive grade and packaging format. Confirm that the HTSSOP-48 pinout aligns with the target PCB layout design. Ensure that the system power supply remains within the specified 8 V to 32 V operational limits to prevent device damage. Check for any specific handling requirements related to moisture sensitivity levels indicated in the datasheet.

Selection Notes

Select this component when designing systems that require robust motor control in harsh automotive environments. It is suitable for applications needing independent control of multiple actuators using a single integrated circuit. Consider the thermal performance characteristics if operating near maximum current limits. Evaluate the package size constraints to ensure compatibility with the available board space.

Part Context

This device belongs to the DRV8823 family of motor drivers developed by Texas Instruments. The Q1 suffix denotes its qualification for automotive use, ensuring compliance with strict industry reliability standards. It serves as a specialized solution for integrating motor drive functionality into complex vehicle electronic control units without requiring external discrete components.

Replacement Considerations

Consult official Texas Instruments documentation for verified cross-reference part numbers. Do not substitute with non-automotive graded variants unless system requirements allow.
