UC3914N TI Power Management IC | 18-PDIP | Dual 1A Gate Driver, 4.5V-18V

Product Overview

The UC3914N from Texas Instruments is a high-performance dual non-inverting gate driver designed for driving MOSFETs and IGBTs in power conversion applications. Housed in an 18-pin PDIP package, it provides two independent output channels capable of sourcing and sinking up to 1A peak current. With a wide supply voltage range of 4.5V to 18V, the UC3914N is suitable for a variety of power management systems, including switch-mode power supplies, motor drives, and DC-DC converters. Its robust design includes undervoltage lockout (UVLO) protection and thermal shutdown, ensuring reliable operation in demanding environments.
