Overview
The UCC21550BDWKR is a dual-channel reinforced isolated gate driver from Texas Instruments, housed in a 14-pin SOIC package. It features a peak output current of 4 A source and 6 A sink. The device provides 5 kVRMS isolation voltage and operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum propagation delay of 45 ns, with rise and fall times of 8 ns each. Power dissipation is rated at 950 mW.
Feature Summary
- Supports universal configurations including dual low-side, dual high-side, or half-bridge driving applications.
- Provides reinforced insulation capability for safety-critical signal transmission between isolated domains.
Applications
- Industrial motor drives
- Solar microinverters
- Switched-mode power supplies
Procurement Notes
Verify the specific suffix 'BDWKR' against the manufacturer's official ordering guide to confirm tape-and-reel packaging and lead-free status. Ensure the design supports the required thermal management for the specified power dissipation. Confirm that the 5 kVRMS isolation rating meets the system's safety standards requirements.
Selection Notes
Select this component when dual-channel isolation with programmable deadtime is required. It is suitable for applications needing high-speed switching with robust noise immunity. Consider the 14-SOIC package constraints for PCB layout. Verify input voltage compatibility with the control logic interface.
Part Context
This part belongs to the UCC21550 family of optically isolated gate drivers. It shares core specifications with variants like the UCC21550ADWKR but may differ in manufacturing lot or specific qualification certifications. The family is designed for high-reliability power conversion systems requiring galvanic isolation.
Replacement Considerations
Direct substitutes include other UCC21550 variants such as UCC21550ADWKR. Verify pinout compatibility and isolation ratings before substitution. Cross-reference with UCC21550BDWR for reel versus cut-tape differences if applicable.
