UCC27201ADPRR

Overview

The UCC27201ADPRR is a high-frequency, half-bridge gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs capable of driving two N-channel MOSFETs in a half-bridge configuration. The device supports a maximum bootstrap voltage of 120V and operates with a supply voltage range of 8V to 17V. It delivers a peak output current of 3A for both sourcing and sinking. Key electrical characteristics include an 8ns rise time and a 7ns fall time under a 1000pF load. The component is housed in an 8-pin VSON package and is rated for operation across a temperature range of -40°C to 140°C.

Feature Summary

• Independent high-side and low-side drivers allow flexible control within half-bridge, full-bridge, and multi-switch converter topologies.
• Integrated 120V bootstrap diode simplifies circuit design by eliminating the need for external high-voltage components.
• Enhanced ESD input structure improves robustness against electrostatic discharge events during handling and operation.
• Negative voltage handling capability on the HS pin ensures reliable performance in noisy power environments.

Applications

• Half-bridge and full-bridge DC-DC converters
• Two-switch forward converters
• Active clamp forward converters
• High-voltage synchronous buck converters

Procurement Notes

Verify the specific suffix 'DPRR' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required automotive or industrial grade specifications. Cross-reference the datasheet revision date to validate the technical parameters provided. Confirm RoHS compliance status through the manufacturer's official product information system before finalizing procurement.

Selection Notes

Select this component when a compact solution is required for driving N-channel MOSFETs in high-frequency switching applications. The integrated bootstrap diode reduces board space and component count compared to discrete solutions. Consider the 3A peak current capability for moderate-power loads. Verify that the 120V bootstrap rating aligns with the maximum bus voltage of the target application. Ensure the operating temperature range meets the environmental requirements of the end-use system.

Part Context

This device belongs to the UCC27200A/1A series of high-speed MOSFET drivers from Texas Instruments. It builds upon the legacy UCC27200/1 architecture with improvements such as enhanced ESD protection and negative voltage tolerance. The series is designed for telecom, datacom, and commercial power supplies. The UCC27201 variant specifically provides 3A drive strength, distinguishing it from lower-current counterparts in the family.

Replacement Considerations

The UCC27201DRMR is a documented alternative within the same series offering identical electrical performance. Verify pin compatibility and thermal characteristics when substituting between different package types such as SOIC-8 and VSON. Ensure that any replacement maintains the 120V bootstrap rating and 3A output current specifications required by the original design.
