Overview
The UCC27324DGNR is a high-speed dual-MOSFET driver produced by Texas Instruments. It is part of the UCC2732x and UCC3732x family, designed to deliver 4-A source and 4-A sink peak current, making it highly effective for driving MOSFETs, particularly during the Miller plateau region. This device features a unique BiPolar and MOSFET hybrid output stage, enabling efficient current sourcing and sinking even at low supply voltages. Available in a thermally enhanced 8-pin PowerPAD MSOP package, it enhances long-term reliability by reducing thermal resistance.
