Overview
The UCC21320QDWKRQ1 is an automotive-grade, isolated dual-channel gate driver featuring a 3.75 kVRMS isolation rating. It provides a 4 A peak source current and a 6 A peak sink current per channel. The device supports input supply voltages (VCCI) ranging from 3 V to 18 V for interfacing with digital or analog controllers. The output drive supply (VDD) can operate up to 25 V. It utilizes capacitive coupling technology for signal transmission across the isolation barrier.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- High-speed capacitive isolation barrier for noise immunity
- Dual independent channels for high-side and low-side driving
Applications
- Driving power MOSFETs in automotive inverters
- Driving IGBTs in traction and motor control systems
- Driving SiC MOSFETs in high-efficiency power conversion
Procurement Notes
Verify the complete part number including suffixes such as 'Q1' for automotive qualification and 'RQ1' for tape-and-reel packaging. Confirm that the specific revision matches the design requirements. Ensure compatibility with the intended controller interface voltage levels before procurement.
Selection Notes
Select this component when automotive reliability and high peak current capability are required. The 4A/6A output strength suits medium-power applications. Verify that the system isolation voltage requirements do not exceed the 3.75 kVRMS rating. Consider thermal management for the SOIC-14 package under continuous load conditions.
Part Context
This device belongs to the UCC21320-Q1 family of isolated gate drivers. It is designed specifically for harsh automotive environments requiring robust isolation between control logic and high-voltage power stages. The Q1 designation indicates compliance with automotive quality standards.
Replacement Considerations
Direct substitutes include other Texas Instruments automotive isolated gate drivers within the same series, provided they meet the 3.75 kVRMS isolation and 4A/6A current specifications. Verify pinout compatibility and electrical parameters before substitution.
