UCC27321DGN General Description

Texas Instruments' UCC27321DGN is a high-performance dual gate driver IC that serves a wide array of power electronics applications. Its unique capability to drive both high-side and low-side MOSFETs or IGBTs in half-bridge, full-bridge, and synchronous buck configurations makes it a versatile solution for various systems. The wide input voltage range of the UCC27321DGN makes it suitable for applications such as motor control, power inverters, and DC-DC converters, offering flexibility for engineers and designers. With a typical propagation delay of 13ns and a maximum output current of 9A, this IC enables fast switching transitions, leading to reduced power losses and improved efficiency in power electronics systems. Additionally, the UCC27321DGN features internal under-voltage lockout (UVLO) protection, over-current protection, and thermal shutdown to ensure its reliability and protect it from potential damage. Packaged in a small-outline IC package (SOIC) with 8 pins, the UCC27321DGN offers compactness and ease of integration, making it a compelling choice for demanding power electronics applications
