UCC27201ADDAR

Overview

The UCC27201ADDAR is a high-frequency N-channel MOSFET gate driver from Texas Instruments, housed in an 8-SO-PowerPad package. It integrates a half-bridge configuration with independent high-side and low-side drivers. The device supports a maximum bootstrap voltage of 120V and operates on a supply voltage range of 8V to 17V. It delivers a peak output current of 3A for both sourcing and sinking. Key timing parameters include an 8ns rise time and a 7ns fall time under a 1000pF load. The component functions within a junction temperature range of -40°C to +140°C.

Feature Summary

• Integrates a 120V bootstrap diode directly on the die to simplify external circuitry.
• Features enhanced ESD input structures designed for robust performance in noisy power environments.
• Provides independent control for high-side and low-side drivers with matched propagation delays.

Applications

• Half-bridge and full-bridge converter topologies
• Two-switch forward converters
• Active clamp forward converters

Procurement Notes

Verify the specific suffix ADDAR corresponds to the SO-PowerPad-8 package when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for applications requiring high-speed switching with integrated bootstrap functionality. The SO-PowerPad package offers improved thermal dissipation compared to standard SOIC variants. Consider the 120V bootstrap rating when designing high-voltage half-bridge circuits where external diodes are undesirable.

Part Context

This part belongs to the UCC27201A series, which enhances the legacy UCC27200/1 family. The A-series introduces improved noise immunity and higher voltage tolerance on the HS pin. It is engineered for commercial and industrial power management systems requiring reliable MOSFET control.

Replacement Considerations

The UCC27201DR serves as a functional equivalent in an 8-SOIC package. Verify pinout compatibility and thermal performance differences between the PowerPAD and standard SOIC footprints before substitution.
