DRV8245SQPWPRQ1

Overview

The DRV8245SQPWPRQ1 is an automotive-grade, fully integrated H-bridge motor driver manufactured by Texas Instruments. It features a dual half-bridge output configuration capable of delivering up to 32 A of continuous current. The device supports both bipolar and unipolar stepper motors as well as brushed DC motors. It operates with a supply voltage range of 4.5 V to 5.5 V for logic and handles load voltages from 4.5 V to 35 V. Communication is facilitated via PWM and SPI interfaces. The component is housed in a 28-HTSSOP package and is qualified to AEC-Q100 standards for operation within a temperature range of -40°C to 125°C.

Feature Summary

• Fully integrated power stage with control logic for simplified system design
• Supports multiple motor types including bipolar/unipolar steppers and brushed DC motors
• Digital control interface utilizing Pulse Width Modulation and Serial Peripheral Interface

Applications

• Automotive seat adjustment actuators

Procurement Notes

Verify the specific suffix 'SQP' to confirm the automotive grade and package variant matches the design requirements. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications. Confirm that the PCB footprint corresponds to the 28-HTSSOP dimensions. Validate that the application environment meets the specified thermal and voltage operating limits defined in the official datasheet.

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 if digital diagnostics and precise control are necessary. Ensure the system voltage does not exceed the maximum load rating. Verify compatibility with the host controller's logic levels and communication protocols before finalizing the design.

Part Context
