UCC21330CQDRQ1

Overview

The UCC21330CQDRQ1 is an automotive-grade, dual-channel isolated gate driver designed for high-power density applications. It features a 3kVRMS isolation barrier with a minimum common-mode transient immunity (CMTI) of 125V/ns. The device provides a peak source current of 4A and a peak sink current of 6A, supporting power MOSFETs, SiC, GaN, and IGBT transistors. It operates within a junction temperature range of -40°C to +150°C and supports supply voltages up to 25V. Key electrical parameters include a typical propagation delay of 33ns, maximum pulse width distortion of 5ns, and maximum VDD turn-on delay of 10μs. The component is housed in a SOIC-16 package.

Feature Summary

• Configurable as two low-side, two high-side, or half-bridge drivers
• Integrated programmable dead time and disable function for simultaneous output shutdown
• Built-in surge elimination filter suppresses input transients shorter than 5ns
• Under-voltage lockout (UVLO) protection provided for all power supplies

Applications

• On-board battery chargers
• High voltage DC-DC converters
• Motor drives

Procurement Notes

Verify the specific suffix 'CQDRQ1' against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the procurement channel sources components directly from authorized distributors to guarantee AEC-Q100 qualification status and traceability. Cross-reference the ordering part number with the manufacturer's latest datasheet revision to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this component when designing systems requiring galvanic isolation between control logic and power stages. It is suitable for applications demanding robust noise immunity, indicated by the high CMTI rating. Consider its dual-channel architecture for cost-effective implementation of half-bridge or full-bridge topologies. Verify that the required peak drive current aligns with the 4A source and 6A sink capabilities of the device.
