SI8273GBD-AS1R

Isolators - Gate Drivers Overview

The SI8273GBD-AS1R is a dual-channel automotive-grade digital isolator gate driver manufactured by Skyworks Solutions. It features a 2500Vrms isolation voltage and high common-mode transient immunity (CMTI). The device operates within a temperature range of -40°C to +125°C and utilizes a 16-SOIC surface-mount package. Key electrical parameters include a maximum propagation delay of 75 ns, rise time of 16 ns, and fall time of 18 ns. It provides peak output currents of 1.8A for the high side and 4A for the low side, with an output supply voltage range of 4.2V to 30V.
