SI8275AB-AM1

Isolators - Gate Drivers Overview

The SI8275AB-AM1 is a dual-channel, galvanically isolated gate driver utilizing Skyworks' proprietary RF coupling technology. It provides 2500Vrms isolation voltage with high common-mode transient immunity (CMTI). The device features a peak output current of 4A and supports an output supply voltage range of 4.2V to 30V. Key electrical parameters include a maximum propagation delay of 75ns, typical rise/fall times of 10.5ns/13.3ns, and a pulse width distortion of 8ns. It operates within a temperature range of -40°C to +125°C and is housed in a 14-QFN (5x5) package.
