XR78021ELTR-F

Overview

The XR78021ELTR-F is a power driver module manufactured by MaxLinear, Inc., designed for high-current motor control applications. It integrates an H-bridge configuration capable of delivering up to 20 A of output current. The device is housed in a 27-pin PowerVQFN package, optimized for surface-mount technology (SMD/SMT) installation. This component functions as a dedicated driver for external MOSFETs or integrated power stages, providing the necessary gate drive signals and protection features required for efficient H-bridge operation in industrial and automotive environments.

Feature Summary

• Integrates a complete H-bridge driver topology for dual-channel motor control
• Supports high continuous output currents up to 20 A per channel
• Utilizes a compact 27-pin PowerVQFN package for efficient thermal management
• Designed for robust performance in demanding industrial and automotive applications

Applications

• Brushed DC motor control systems
• Industrial automation actuators
• Automotive electronic control units (ECUs)
• Power tool motor drivers

Procurement Notes

Verify component authenticity through authorized distributors only. Confirm that the specific suffix 'TR-F' matches the reel packaging requirement for your assembly line. Ensure compatibility with existing PCB footprints and thermal design specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution for high-current H-bridge driving is required. Consider the 20 A current rating and PowerVQFN thermal performance relative to your system's heat dissipation capabilities. Evaluate interface voltage levels and protection features against your specific motor load requirements.

Part Context

This part belongs to MaxLinear's power driver module family, specifically tailored for H-bridge configurations. It complements other switching regulators and controllers within the portfolio by focusing on the final stage of power delivery to motors or loads, rather than voltage conversion itself.

Replacement Considerations

Consult official MaxLinear documentation for direct pin-to-pin substitutes. Verify electrical parameters such as current handling and package dimensions if considering alternative manufacturers.
