Product Description
Product Overview
The Si827x isolators are 4 Amp ISOdrivers designed for driving power switches in power supply, inverter, and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, they offer industry-leading common-mode transient immunity (CMTI), tight timing specifications, and high reliability. Key features include separate pull-up/down outputs, driver shutdown on UVLO fault, and precise dead-time programmability, making them a cost-effective and flexible solution for isolated MOSFET/IGBT and SiC or GaN FET gate drive applications.
