Overview
The UCC37322DGNG4 is a single 9-A high-speed low-side MOSFET driver produced by Texas Instruments. This component is designed to provide high gate drive current, particularly during the Miller plateau region of MOSFET switching transitions. It features a unique hybrid output stage that combines bipolar and MOSFET transistors, known as TrueDrive, which allows for efficient current delivery even at low supply voltages. The device includes an enable function for better control over the operation of the driver applications and is available in thermally enhanced packages such as the 8-pin MSOP PowerPAD™ (DGN) package, which significantly reduces thermal resistance and improves long-term reliability.
