UCC5310MCDR

Overview

The UCC5310MCDR is a single-channel isolated gate driver from Texas Instruments, housed in an 8-pin SOIC (D) package. It provides galvanic isolation with ratings of 3kVrms or 5kVrms depending on configuration. The device features peak output currents of 2A for the high-side and 1A for the low-side outputs, with enhanced performance variants offering up to 4.3A and 2.2A respectively. Key electrical parameters include a maximum propagation delay of 75 ns, a rise time of 12 ns, and a power dissipation of 1.14 W. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates Miller clamp functionality to prevent false turn-on events during high dv/dt switching conditions.
• Utilizes capacitive coupling technology to achieve reinforced or basic isolation barriers without optical components.
• Provides single-channel drive capability with independent high-side and low-side output stages.

Applications

• Gate driving for silicon carbide (SiC) MOSFETs in high-frequency power converters.
• Isolated control interfaces for insulated-gate bipolar transistors (IGBTs).
• High-voltage bridge drivers in motor drives and industrial inverters.

Procurement Notes

Verify the specific isolation rating (3kVrms vs 5kVrms) required for your application design, as this may depend on the ordering suffix or configuration. Confirm that the SOIC-8 package thermal characteristics meet your system's heat dissipation requirements. Ensure compatibility with your logic input voltage levels before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel isolated drive solution with integrated Miller clamp protection is needed. Consider the UCC5310 series if capacitive coupling offers better reliability than optical alternatives for your environment. Evaluate the 2A/1A versus 4.3A/2.2A current capabilities based on the gate charge requirements of the target power switch.

Part Context

This part belongs to the UCC53x0 family of single-channel isolated gate drivers. It serves as a bridge between low-voltage control logic and high-voltage power switches. The 'DR' suffix indicates tape-and-reel packaging for automated assembly, distinguishing it from tube-packaged variants like the UCC5310MCD.

Replacement Considerations

Direct substitutes within the same family include the UCC5310MCD for non-reel packaging. For higher current requirements, consider the UCC5311 series. Verify pinout compatibility and isolation voltage ratings when cross-referencing with other manufacturers' isolated gate drivers.
