DRV8411PWPR

Overview

The DRV8411PWPR is a dual H-bridge motor driver IC manufactured by Texas Instruments, designed for driving bipolar stepper motors, brushed DC motors, and inductive loads. It features a wide supply voltage range of 8.2 V to 45 V and supports an output current of 1.75 A. The device utilizes a 28-pin HTSSOP package with surface-mount installation. Key electrical specifications include a minimum operating temperature of -40°C and a maximum junction temperature of 150°C. It incorporates integrated protection mechanisms such as overcurrent protection and thermal shutdown.

Feature Summary

• Dual H-bridge architecture capable of driving bipolar stepper motors or two brushed DC motors
• Integrated current regulation via external sense resistor for precise control
• Comprehensive internal protection including UVLO, automatic retry OCP, and thermal shutdown

Applications

• Bipolar stepper motor control systems
• Brushed DC motor drives
• Solenoid actuation applications
• Inductive load switching

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package and tape-and-reel orientation. Confirm that the 8.2V minimum supply requirement aligns with your system's power rail capabilities. Ensure thermal management strategies account for the 150°C junction limit during high-current operation. Cross-reference the datasheet revision date to confirm compatibility with your design requirements.

Selection Notes

Select this component when a robust dual H-bridge solution is required for higher voltage applications up to 45 V. It is suitable for designs needing integrated current sensing and protection without external discrete components. Consider the 28-pin footprint for PCB layout constraints. Evaluate the 1.75 A continuous current rating against peak load demands to ensure adequate thermal headroom.

Part Context

The DRV8411 belongs to Texas Instruments' family of dual H-bridge motor drivers. It offers pin-to-pin compatibility with other devices like the DRV8833 and DRV8847, facilitating design scalability. The PWPR variant specifically denotes the HTSSOP-28 package configuration, distinguishing it from smaller QFN or SOT options available in the same series.

Replacement Considerations

Public confirmed substitute part numbers include DRV8841PWPR and DRV8833PWP. These alternatives offer similar dual H-bridge functionality but may differ in on-resistance, voltage ranges, or current capabilities. Verify pinout compatibility and electrical specifications before substitution.
