Overview
The UCC21521DWR is a galvanically isolated dual-channel gate driver from Texas Instruments, housed in a 16-pin SOIC package. It delivers a peak source current of 4 A and a sink current of 6 A. The device supports an operating temperature range from -40°C to +125°C with a maximum propagation delay of 30 ns. Key timing characteristics include a rise time of 6 ns and a fall time of 7 ns. It features a power dissipation rating of 1.05 W and provides 5.7 kVRMS isolation capability for driving power MOSFETs, IGBTs, and SiC MOSFETs.
Feature Summary
- Provides universal configuration support for dual low-side, dual high-side, or half-bridge topologies
- Integrates programmable deadtime control and enable functionality for precise switching management
- Offers reinforced electrical isolation suitable for demanding power electronics applications
Applications
- Driving silicon carbide (SiC) MOSFETs in high-frequency power converters
- Controlling insulated-gate bipolar transistors (IGBTs) in industrial motor drives
- Implementing half-bridge configurations in DC-DC conversion systems
Procurement Notes
Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-SOIC footprint matches the target PCB layout dimensions. Ensure the component meets RoHS compliance standards as indicated by the manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when high-speed switching with robust isolation is required for wide-bandgap semiconductors. The integrated programmable deadtime simplifies design complexity compared to discrete solutions. Consider the thermal performance limits defined by the 1.05 W power dissipation rating under continuous operation conditions within the specified temperature range.
Part Context
This part belongs to the UCC21521 series of isolated gate drivers designed for modern power electronics. It complements other variants like the UCC21521CDWR and UCC21521ADWR, which share similar electrical characteristics but may differ in packaging or qualification levels. The series addresses the growing demand for efficient isolation in next-generation energy conversion systems.
Replacement Considerations
Direct substitutes include UCC21521CDWR and UCC21521ADWR. Verify pinout compatibility and ensure the alternative variant meets the same isolation voltage and current drive requirements for seamless integration into existing designs.
