SI8234AD-D-IS

Isolators - Gate Drivers Overview

The SI8234AD-D-IS is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It features a 5 kVrms isolation voltage and operates within a temperature range of -40°C to +125°C. The device supports high-side and low-side configurations with TTL logic inputs between 4.5 V and 5.5 V. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 12 ns each, and a maximum turn-on/turn-off delay of 60 ns. It has a power dissipation of 1.2 W, operates at 3.5 mA supply current, and is housed in a 16-SOIC-Wide package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D-IS' corresponds to the SOIC-Wide-16 package and tube packaging format as listed in official Skyworks documentation. Confirm that the 5 V UVLO specification matches the system requirements, distinguishing it from variants with different undervoltage lockout thresholds. Ensure compatibility with the SI8234-KIT development resources if prototyping is planned.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated gate driver with 5 kVrms isolation and AEC-Q100 certification is required. It is suitable for applications needing high-side and low-side drive capabilities with TTL input compatibility. Consider the 16-SOIC-Wide package for surface-mount assembly and verify thermal management needs against the 1.2 W power dissipation rating.
