UCC27201ADR

Overview

The UCC27201ADR is a half-bridge gate driver manufactured by Texas Instruments, designed for high-frequency N-channel MOSFET control. It features a 3 A peak output current and supports a maximum bootstrap voltage of 120 V. The device operates within an 8 V to 17 V supply range and includes an integrated 0.65 V forward voltage, 0.6 Ω resistance bootstrap diode. Key timing parameters include an 8 ns rise time, 7 ns fall time, and 1 ns delay matching between high-side and low-side drivers. It utilizes non-inverting inputs and offers independent control flexibility.

Feature Summary

• Integrates a high-performance bootstrap diode with specified forward voltage and on-resistance values directly on the die.
• Provides independent high-side and low-side drive channels with matched propagation delays for precise switching control.
• Features enhanced ESD protection structures and negative voltage handling capabilities on the high-side pin.

Applications

• Half-bridge and full-bridge power converter topologies
• Two-switch forward converters and active-clamp forward converters
• High-voltage synchronous buck converters

Procurement Notes

Verify the specific suffix 'ADR' corresponds to the SOIC-8 package and reel packaging configuration as listed in official documentation. Confirm RoHS compliance status and ensure the component meets the required operating temperature range specifications before integration into final designs.

Selection Notes

Select this component when a 3 A drive capability and 120 V bootstrap rating are required for N-channel MOSFETs. The SOIC-8 package suits applications needing standard surface-mount assembly. Consider the integrated bootstrap diode characteristics and 1 ns delay matching for high-frequency performance requirements.

Part Context

This part belongs to the UCC27201A series, which enhances the legacy UCC27200/1 family with improved ESD protection and negative voltage handling. It is engineered for robust performance in noisy power environments, offering greater control flexibility compared to previous generations through independent channel operation.

Replacement Considerations

The UCC27201DR serves as a direct functional equivalent within the same product family, sharing identical electrical specifications and pinout configurations while differing primarily in package type and manufacturing lot details.
