Overview
The UCC27322DR is a high-speed, single-channel gate driver produced by Texas Instruments. It is part of the UCC2732x/UCC3732x family, known for delivering 9 A of peak drive current in an industry-standard pinout. This driver is designed to handle the largest of MOSFETs, particularly in systems requiring high Miller current due to high dV/dt transitions. The UCC27322DR eliminates the need for additional external circuits, reducing space, design complexity, and assembly costs. It is available in an 8-pin SOIC (D) package and also in a thermally enhanced MSOP PowerPAD™ package, which improves thermal performance and long-term reliability.
