UCC21520DW

The UCC21520DW is a high-performance, isolated dual-channel gate driver developed by Texas Instruments. It is designed to efficiently drive MOSFETs and IGBTs in various power conversion applications. Key features include a 5.7 kV RMS reinforced isolation, which ensures robust separation between the input and output stages, and a high common-mode transient immunity (CMTI) greater than 100 V/ns, minimizing noise interference. The device offers flexible output configurations, supporting both dual low-side, dual high-side, and half-bridge arrangements. It provides peak output currents of up to 4 A and 6 A, allowing it to handle demanding power requirements. The UCC21520DW includes an interlock feature to prevent both outputs from being high simultaneously, enhancing safety in half-bridge applications. It operates over a wide temperature range from -40°C to 125°C, making it suitable for harsh environments. Moreover, the driver features undervoltage lockout (UVLO) protection for both input and output sides, ensuring reliable operation. Its small 16-pin SOIC package facilitates compact designs in industrial, automotive, and renewable energy systems.
