Overview
The UCC21550AQDWKRQ1 is an automotive-grade, dual-channel optically isolated gate driver from Texas Instruments. It features reinforced isolation with a 5 kVRMS rating and supports output currents of 4 A and 6 A. The device operates within a temperature range of -40°C to +150°C and utilizes a SOIC-14 package. Key electrical parameters include a maximum propagation delay of 45 ns, rise/fall times of 8 ns, and a power dissipation of 950 mW. Input voltage ranges up to 5.5 V, while output voltages span 13 V to 25 V.
Feature Summary
- Provides reinforced optical isolation for high-voltage noise immunity in automotive environments
- Supports flexible configurations including dual low-side, dual high-side, or half-bridge driving
- AEC-Q100 qualified for Grade 1 temperature performance ensuring automotive reliability
Applications
- Automotive electric vehicle (EV) traction inverters
- On-board chargers (OBC) and DC-DC converters
- Industrial motor drives requiring high isolation
Procurement Notes
Verify the specific suffix 'RQ1' confirms AEC-Q100 qualification and tape-and-reel packaging. Ensure the SOIC-14 footprint matches the design layout. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the datasheet revision to ensure compatibility with current design specifications.
Selection Notes
Select this component when automotive certification and high common-mode transient immunity are required. The dual-channel architecture simplifies half-bridge designs compared to single-channel alternatives. Consider the 5 kVRMS isolation barrier for safety-critical applications. Evaluate thermal management needs given the 950 mW power dissipation in the SOIC-14 package.
Part Context
This part belongs to the UCC21550x-Q1 family of automotive isolated gate drivers. It complements other TI solutions like the UCC21551 by offering specific isolation ratings and current capabilities tailored for electric powertrain systems. The series emphasizes robustness against electromagnetic interference in noisy automotive electrical environments.
Replacement Considerations
The UCC21550ADWKR is a non-automotive version with similar electrical characteristics but lacks AEC-Q100 qualification. Verify if automotive grade certification is mandatory for the target application before substituting.
