Overview
The UCC21521ADW is a dual-channel isolated gate driver from Texas Instruments, housed in a 16-SOIC package. It provides galvanic isolation with a rating of 5.7 kVRMS. The device supports peak output currents of 4 A and 6 A for low-side and high-side configurations respectively. It operates within an extended temperature range of -40°C to +125°C. Key electrical specifications include a maximum propagation delay of 30 ns. The component features programmable deadtime and enable functionality, designed for robust performance in power conversion applications.
Feature Summary
- Universal topology support for dual low-side, dual high-side, or half-bridge configurations
- Integrated programmable deadtime control to prevent shoot-through
- High-voltage galvanic isolation barrier rated at 5.7 kVRMS
- Enable pin functionality for precise channel control
Applications
- Half-bridge power converter topologies
- Dual low-side switching applications
- Dual high-side switching applications
- Industrial motor drive systems
Procurement Notes
Verify the specific suffix 'DW' corresponds to the SOIC-16 package variant when sourcing. Confirm that the order quantity aligns with the manufacturer's standard reel packaging requirements. Ensure the procurement documentation explicitly references the UCC21521ADW part number to distinguish it from other variants in the UCC21521 family. Check for moisture sensitivity labeling as indicated in product attributes.
Selection Notes
Select this component when a dual-channel isolated driver with integrated deadtime is required. The 5.7 kVRMS isolation rating suits applications demanding reinforced insulation. Consider the 4A/6A current capability for driving medium-power GaN or SiC devices. The wide operating temperature range makes it suitable for industrial environments. Ensure the PCB layout accommodates the 16-SOIC footprint and isolation creepage distances.
Part Context
The UCC21521ADW belongs to the UCC21521 series of isolated gate drivers. This series is characterized by its flexibility in supporting various bridge configurations through internal logic. The ADW suffix specifically denotes the automotive-grade or extended temperature variant in the SOIC-16 package. It complements other Texas Instruments isolation products by providing a complete solution for high-speed switching control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Users should consult official Texas Instruments documentation for cross-reference information or contact technical support for compatible alternatives.
