Overview
The UCC21331CDR is a dual-channel isolated gate driver from Texas Instruments, housed in a 16-pin SOIC (D) package. It provides peak output currents of 4A and 6A for its two channels. The device features a 3.0kVRMS isolation barrier and operates within a junction temperature range of -40°C to +150°C.
Feature Summary
- Supports universal configurations including dual low-side, dual high-side, or half-bridge driving applications.
- Provides robust signal isolation with a 3.0kVRMS barrier for safety and noise immunity.
- Capable of delivering high peak source and sink currents to efficiently drive power switches.
Applications
- Industrial motor drives
- Inverter systems
- Switched-mode power supplies
Procurement Notes
Verify the specific suffix 'CDR' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the AEC-Q100 Grade 1 qualification meets your automotive reliability standards if applicable. Ensure the 16-SOIC footprint matches your PCB design constraints before finalizing orders.
Selection Notes
Select this component when a dual-channel solution with basic isolation is required for bridge topologies. The 4A/6A current capability suits medium-power switching applications. Consider the 150°C maximum junction temperature for high-thermal environments where standard 125°C devices may be insufficient.
Part Context
This part belongs to the UCC21331x family of isolated gate drivers. It utilizes capacitive coupling technology to transmit signals across the isolation barrier. The family includes variants with different current ratings and pinout configurations to support diverse power electronics designs.
Replacement Considerations
Check for UCC21330 or UCC21332 equivalents if different current ratings are needed. Verify pin compatibility with other UCC213xx series devices before substitution.
FAQ
What isolation technology does the UCC21331CDR use?
It uses capacitive coupling technology to provide galvanic isolation between the input and output sides.
Is the UCC21331CDR qualified for automotive applications?
Yes, it is AEC-Q100 qualified with Device Temperature Grade 1.
