UCC27210DDAR

Gate Driver Overview

The UCC27210DDAR is a high-frequency half-bridge MOSFET gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs capable of driving N-channel MOSFETs with a peak output current of 4A for both sourcing and sinking. The device supports a maximum bootstrap voltage of 120V DC and operates within an 8V to 17V supply range, with absolute maximum ratings up to 20V. It exhibits fast switching characteristics, including a typical rise time of 7.2ns and fall time of 5.5ns under a 1000pF load. The input pins tolerate voltages from -10V to 20V independently of the power supply. It is housed in an SO-PowerPad-8 package and rated for operation between -40°C and +140°C.

Gate Driver Feature Summary

• Provides 4A peak source and sink currents to minimize switching losses during Miller plateau transitions
• Features TTL or pseudo-CMOS compatible inputs that are independent of the VDD supply voltage
• Supports direct interface with gate drive transformers without requiring rectification diodes

Gate Driver Applications

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

Gate Driver Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 PowerPAD package and 'R' denotes reel packaging when ordering. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the supplier provides valid traceability documentation. Cross-reference the manufacturer part number against official Texas Instruments databases to avoid counterfeit components. Check for any recent product change notices affecting specifications.

Gate Driver Selection Notes

Select this component for applications requiring robust high-side driving capabilities with a 120V bootstrap rating. It is suitable for designs needing fast propagation delay matching of approximately 2ns. Consider the independent input structure for simplified transformer coupling. Evaluate the thermal performance of the PowerPAD package for high-power density implementations. Ensure the control logic aligns with the specified TTL or pseudo-CMOS input thresholds.

Gate Driver Part Context

This device belongs to the UCC2721x series, which represents an evolution of the popular UCC27200 and UCC27201 drivers. It offers significantly improved performance with doubled peak output currents and reduced internal resistance. The series maintains compatibility with previous generations while enhancing durability and speed for modern power conversion topologies.

Gate Driver Replacement Considerations

UCC27210D serves as a tube-packaged alternative with identical electrical specifications. UCC27211 variants offer inverted logic options if signal phase reversal is required. Verify pinout compatibility and thermal pad connectivity when substituting.
