UCC21330BDR

Overview

The UCC21330BDR is a dual-channel isolated gate driver from Texas Instruments, housed in a 16-pin SOIC package. It features a 4A peak source and 6A peak sink current capability, supporting power MOSFETs, SiC, GaN, and IGBT transistors. The device operates with a supply voltage range of 8V to 25V and includes UVLO protection for all supplies. Key electrical parameters include a typical propagation delay of 33 ns, maximum pulse width distortion of 5 ns, and a maximum VDD turn-on delay of 10 μs. It offers a CMTI greater than 125 V/ns and functions within a junction temperature range of -40°C to +150°C.

Feature Summary

• Dual-channel configuration supports two low-side, two high-side, or half-bridge topologies.
• Programmable deadtime and disable function allow precise switching control and simultaneous output shutdown.
• Integrated surge elimination filter suppresses input transients shorter than 5 ns.
• Capacitive coupling provides isolation with high common-mode transient immunity.

Applications

• On-board battery chargers
• High-voltage DC-DC converters
• Automotive HVAC systems
• Automotive body electronics

Procurement Notes

Verify the specific suffix 'BDR' corresponds to the 16-SOIC package and tape-and-reel packaging format. Confirm AEC-Q100 qualification status if automotive grade requirements are mandatory. Ensure the design accounts for the 125 V/ns CMTI rating relative to the application's dv/dt conditions. Validate that the 4A/6A drive strength matches the target power device gate charge requirements at the intended operating voltage.

Selection Notes

Select this component when a dual-channel isolated driver with programmable deadtime is required for compact designs. It is suitable for applications needing robust noise immunity via integrated filtering and high CMTI. Consider the wide operating temperature range for harsh environments. Verify compatibility with CMOS/TTL logic inputs and ensure sufficient PCB space for the 16-SOIC footprint and isolation creepage distances.

Part Context

The UCC21330 family belongs to Texas Instruments' series of isolated gate drivers designed for high-efficiency and high-power-density applications. This specific part number denotes the commercial-grade version in a standard SOIC package, distinct from the automotive-qualified Q1 variants. It shares core functionality with other members of the family but differs in qualification standards and specific package options available across the product line.

Replacement Considerations

Direct replacements include other UCC21330 variants such as UCC21330QDRQ1 for automotive applications or UCC21330BDWR for different packaging. Cross-family alternatives like UCC21520 offer similar isolation but may differ in channel count or drive strength. Always verify pinout compatibility and electrical specifications before substitution.
