Overview
The UCC21520AQDWRQ1 is an automotive-grade, isolated dual-channel gate driver designed for high-speed power switching applications. It features a 5.7-kVRMS isolation rating and delivers a peak output current of 4 A source and 6 A sink. The device supports operation up to 5 MHz with a maximum propagation delay of 30 ns, rise time of 6 ns, and fall time of 7 ns. It operates within a supply voltage range of 6.5 V to 25 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-SOIC surface-mount format, it includes CMOS/TTL compatible logic inputs.
Feature Summary
- Provides galvanic isolation via capacitive coupling technology with a 5.7-kVRMS rating
- Optimized for high-frequency switching with best-in-class propagation delay and pulse-width distortion
- Automotive qualification compliant with AEC-Q100 standards for reliability
Applications
- Driving power MOSFETs, IGBTs, and SiC MOSFETs
- Automotive inverter and converter circuits
- High-density motor drive systems
Procurement Notes
Verify the specific suffix Q1 confirms automotive grade status and AEC-Q100 compliance. Ensure the SOIC-16 package matches board layout requirements. Confirm moisture sensitivity levels and reflow soldering profiles align with assembly capabilities. Validate that the 5.7-kVRMS isolation rating meets system safety standards.
Selection Notes
Select this component when high-speed switching above 1 MHz is required alongside robust galvanic isolation. The dual-channel architecture suits half-bridge and full-bridge topologies. Consider the 6 A sink capability for driving low-impedance loads efficiently. Verify input logic compatibility with standard CMOS or TTL signals.
Part Context
This part belongs to the UCC21520 series of isolated gate drivers from Texas Instruments. It represents the automotive-qualified variant (Q1) of the commercial UCC21520DW. The series utilizes capacitive isolation to replace traditional magnetic couplers, offering higher bandwidth and smaller form factors for modern power electronics.
Replacement Considerations
The UCC21520DW is the commercial equivalent without automotive qualification. Verify if AEC-Q100 certification is mandatory for the target application before substituting.
