SI8235BB-D-IM1

Isolators - Gate Drivers Overview

The SI8235BB-D-IM1 is a dual-channel, galvanically isolated gate driver manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide signal isolation with a rated voltage of 2.5 kVrms. The device features an 8 V undervoltage lockout (UVLO) and delivers a peak output current of 4 A. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 12 ns, and a maximum pulse width distortion of 5.6 ns. It operates within a temperature range of -40°C to +125°C and is housed in a 14-pin QFN package.
