DRV8874QPWPRQ1

Overview

The DRV8874QPWPRQ1 is an automotive-grade H-bridge motor driver designed for high-current applications. It supports a supply voltage range of 4.5 V to 40 V and delivers up to 6 A continuous output current. The device integrates a 3-V logic-compatible interface, enabling direct connection to microcontrollers. Key protection features include overcurrent protection with cycle-by-cycle limiting, thermal shutdown, and undervoltage lockout. Packaged in a PWPR QFN solution, it ensures reliable operation across the -40°C to +125°C junction temperature range.

Feature Summary

• Integrated H-bridge architecture supporting bidirectional control for DC motors
• Built-in overcurrent protection with adjustable threshold and cycle-by-cycle limiting
• Thermal shutdown mechanism to prevent damage during overheating conditions
• Undervoltage lockout feature ensuring stable startup and operation

Applications

• Automotive power window actuators
• Seat adjustment motor control systems
• Electronic power steering components

Procurement Notes

Verify that the specific part marking matches the DRV8874QPWPRQ1 designation exactly. Confirm the package type corresponds to the specified QFN variant. Ensure the component meets the required automotive qualification standards for your specific application environment. Cross-reference the datasheet revision to confirm compatibility with your design requirements.

Selection Notes

Select this component when a robust single-chip solution is needed for driving DC motors in automotive environments. It is suitable for applications requiring moderate current levels up to 6 A without external heat sinks. Consider the integrated protection features to simplify system design and reduce bill of materials compared to discrete solutions.

Part Context

This device belongs to Texas Instruments' family of automotive motor drivers. It complements other products like the DRV8873 and DRV8904 by offering a balance between current capacity and integration level. The series focuses on providing reliable performance for critical vehicle subsystems while maintaining ease of implementation for engineers.

Replacement Considerations

Direct substitutes within the same family include the DRV8873QPWPRQ1 for higher current needs or the DRV8876QPWPRQ1 for different pin configurations. Verify pin-to-pin compatibility before swapping. Check if the alternative part number offers sufficient current rating and protection features for the specific load.
