DRV8402DKD

Overview

The DRV8402DKD is a dual full-bridge PWM motor driver manufactured by Texas Instruments. It integrates high-efficiency power stages capable of delivering up to 10A continuous current per bridge with peak currents reaching 12A. The device operates within a supply voltage range of 5.5V to 50V and utilizes an HSSOP-36 package. Key electrical characteristics include a typical on-resistance of 170mΩ per half-bridge and integrated charge pumps for gate drive. It supports PWM frequencies up to 100kHz and includes features such as overcurrent protection, thermal shutdown, and undervoltage lockout.

Feature Summary

• Integrates two independent full-bridge drivers for precise control of brushed DC motors
• Features high-efficiency power stage design to minimize heat generation during operation
• Includes comprehensive protection mechanisms against overcurrent, overtemperature, and undervoltage conditions

Applications

• General purpose brushed DC motor control in industrial automation
• Motion control systems requiring dual motor actuation
• Home appliance motor drives

Procurement Notes

Verify the specific suffix DKD corresponds to the HSSOP-36 package variant when sourcing. Confirm lifecycle status as NRND (Not Recommended for New Designs) impacts long-term availability. Ensure compatibility with system voltage requirements between 5.5V and 50V. Check for RoHS3 compliance documentation if environmental regulations apply to your deployment.

Selection Notes

Select this component when dual isolated motor channels are required in a compact form factor. Consider the 10A continuous current rating relative to load demands. Evaluate thermal management needs given the power dissipation at higher loads. Verify that the 36-pin HSSOP package fits the PCB layout constraints compared to alternative packages like DSBGA or VQFN.

Part Context

This part belongs to the DRV8402 family of motor drivers from Texas Instruments. It serves as a fully integrated solution combining control logic and power MOSFETs. The DKD suffix specifically denotes the HSSOP-36 surface-mount package variant. It is designed to simplify motor control designs by reducing external component count while maintaining robust performance standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the same TI family. Verify if newer generations have superseded this NRND part. Ensure substitute components match the 50V maximum voltage rating and 10A current capability. Confirm package dimensions align with existing footprints.
