Overview
The UCC21520QDWQ1 is an automotive-grade, dual-channel isolated gate driver designed for high-performance power switching applications. It features a peak output current capability of 4A source and 6A sink, supporting the drive of power MOSFETs, IGBTs, and SiC MOSFETs. The device provides 5700 Vrms isolation voltage and high common-mode transient immunity of 100V/ns. It operates within a supply voltage range of 6.5V to 25V per channel and includes an 8V undervoltage lockout (UVLO). The component is housed in a 16-pin SOIC package with a wide operating temperature range from -40°C to 125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- High common-mode transient immunity of 100V/ns for noise resilience
- Dual-channel architecture with independent input and disable pins
- Robust isolation barrier rated at 5700 Vrms
Applications
- Automotive motor drives
- High-current inverter circuits
- SiC and GaN power stage driving
Procurement Notes
Verify that the specific order quantity matches the manufacturer's minimum packaging requirements, typically tape and reel formats for this series. Confirm the presence of the Q1 suffix to ensure automotive grade compliance and AEC-Q100 certification are included in the shipment documentation. Cross-reference the date code and lot number against the latest Texas Instruments quality notifications to ensure component integrity and traceability before final acceptance.
Selection Notes
Select this component when automotive reliability and high-speed switching performance are required for isolated gate drive applications. The 6A sink current capability makes it suitable for driving large capacitive loads or fast-switching wide-bandgap devices like SiC MOSFETs. Ensure the system design accommodates the 16-pin SOIC thermal dissipation limits and utilizes the dual-input feature if signal redundancy or logic control flexibility is needed.
Part Context
This device belongs to the UCC21520 family of isolated gate drivers from Texas Instruments. It shares functional similarities with the standard UCC21520 but is specifically qualified for automotive environments. The Q1 designation indicates adherence to stricter automotive quality and reliability standards compared to commercial variants.
Replacement Considerations
The UCC21520DW serves as a non-automotive equivalent. Verify that the application does not require AEC-Q100 certification if substituting with the commercial version.
