SI8273GA-AM1R

Isolators - Gate Drivers Overview

The SI8273GA-AM1R is a digital isolator gate driver from Skyworks Solutions, part of the Si827x series. It features a single channel with high common-mode transient immunity (CMTI) and operates within an extended temperature range of -40°C to +125°C. The device utilizes radio frequency coupling technology for galvanic isolation. It supports input voltages between 2.5 V and 5.5 V and drives outputs with supply voltages ranging from 4.2 V to 30 V. The component is housed in a 14-VDFN package and is designed for high-speed applications requiring low latency.
