SI8275AB-IM1

Isolators - Gate Drivers Overview

The SI8275AB-IM1 is a dual-channel, galvanically isolated gate driver from Skyworks Solutions. It utilizes capacitive coupling technology to provide high common-mode transient immunity (CMTI) of 200 kV/µs and an isolation voltage of 2500 Vrms. The device features a 14-pin QFN package with dimensions of 5x5 mm. Key electrical parameters include a maximum propagation delay of 75 ns, rise time of 16 ns, and fall time of 18 ns. It operates within a temperature range of -40°C to +125°C and consumes 10 mA of supply current. The output stage delivers up to 4 A peak current.
