Product Introduction

Overview

The UCC27425DGNR is a high-speed dual MOSFET driver from Texas Instruments, part of the UCC2742x family. This component is designed to deliver large peak currents into capacitive loads, making it suitable for applications requiring high current drive capability. The UCC27425 specifically features one inverting channel (A) and one non-inverting channel (B), providing flexibility in driving external MOSFETs. Available in a thermally enhanced 8-pin PowerPAD™ MSOP package (DGN), this driver enhances long-term reliability by drastically lowering thermal resistance.
