SI8274AB4D-IMR

Isolators - Gate Drivers Overview

The SI8274AB4D-IMR is a dual-channel digital isolator gate driver manufactured by Skyworks Solutions Inc. It utilizes radio frequency (RF) coupling technology to provide galvanic isolation with a rating of 2500 Vrms. The device features high common-mode transient immunity (CMTI) of 200 kV/μs and latch-up immunity of 400 kV/μs. It supports a supply voltage range of 4.6 V to 30 V for the output side and includes a 5 V under-voltage lockout (UVLO). The component is housed in a 14-LGA (5x5) package and operates within a temperature range of -40°C to +125°C.
