DRV8243SQDGQRQ1

Overview

The DRV8243SQDGQRQ1 is an automotive-grade, fully integrated H-bridge motor driver manufactured by Texas Instruments. It supports bipolar stepper and brushed DC motors with a supply voltage range of 4.5V to 35V and delivers up to 12A output current. The device utilizes NMOS technology and features an SPI interface for configuration. It operates within a temperature range of -40°C to +125°C and is housed in a 28-HTSSOP package.

Feature Summary

• Fully integrated control and power stages for simplified system design
• SPI interface enables precise digital control and monitoring
• Automotive qualification ensures reliability in harsh environments

Applications

• Automotive active headlight leveling systems
• Vehicle seat adjustment actuators
• Electronic power steering components
• Thermal management fans in automotive applications

Procurement Notes

Verify the specific suffix 'SQDGQRQ1' to confirm the automotive grade, HTSSOP package, and reel quantity. Ensure compatibility with the target vehicle's voltage profile and thermal requirements. Cross-reference the latest datasheet revision for any pinout or electrical characteristic updates before finalizing the bill of materials.

Selection Notes

Select this component when high current drive capability is required for automotive motion control applications. The integrated nature reduces external component count compared to discrete solutions. Consider the SPI interface requirement for complex control logic versus simpler PWM-only drivers. Verify that the 28-pin form factor fits the available PCB real estate constraints.

Part Context

This part belongs to the DRV8243-Q1 family of high-current H-bridge drivers designed specifically for automotive markets. It complements lower-current variants like the DRV8212 series by offering higher power handling capabilities suitable for larger actuators. The family shares common integration features but differs in current ratings and package options.

Replacement Considerations

The DRV8243HQDGQRQ1 is listed as a parameter-equivalent alternative within the same product family. Verify if the specific sub-model variant meets all functional requirements before substitution.
