SI823H9CD-IS4R

Isolators - Gate Drivers Overview

The SI823H9CD-IS4R is a galvanically isolated single-channel gate driver from the Si823Hx series, manufactured by Skyworks Solutions. It features a wide operating supply voltage range of 10.5 V to 26 V for both the source and drain sides. The device provides a peak output current of 2 A and supports high-speed switching with a maximum propagation delay of 75 ns. It utilizes silicon isolation technology to achieve a reinforced isolation voltage rating of 5 kVrms. The component is housed in an 8-lead Small Outline package (SSO-8) and is designed for surface-mount installation.
