SI8234BB-AS

Isolators - Gate Drivers Overview

The SI8234BB-AS is a dual-channel, galvanically isolated gate driver from the Si823x series by Skyworks Solutions. It features a 2.5 kVrms isolation voltage and an 8 V undervoltage lockout (UVLO). The device operates within a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC-Wide package. It provides high-side and low-side outputs with a maximum propagation delay of 45 ns, rise/fall times of 12 ns, and a power dissipation rating of 1.2 W.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation for driving high-speed power MOSFETs and IGBTs
