SI8234AB-AS

Isolators - Gate Drivers Overview

The SI8234AB-AS is a half-bridge based IGBT/MOSFET driver from the Si823x series, manufactured by Skyworks Solutions. It features a 2.5 kVrms galvanic isolation barrier and operates within an input voltage range of 4.5 V to 5.5 V. The device utilizes a 16-pin SOIC-16 (PDSO16) package with a maximum height of 1.75 mm. It supports an operating temperature range from -40 °C to +125 °C and holds AEC-Q100 qualification for automotive applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm pinout and electrical characteristics, as ordering codes may vary. Ensure compatibility with the required 16-pin SOIC package dimensions and thermal management requirements for the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel half-bridge driver with automotive reliability is required. The 5 V UVLO threshold distinguishes it from variants with different thresholds. Confirm that the 4 A peak output current capability meets the gate charge requirements of the target power devices.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of ISOdrivers, which are designed for robust performance in noisy environments. The family includes various configurations with different isolation voltages and UVLO settings, all sharing similar digital isolation technology and packaging options for flexible system integration.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks datasheets for direct substitutes such as SI8234AB-D-IS or SI8234BB-D-IS. Verify that alternative parts match the 2.5 kV isolation rating, 16-pin SOIC package, and AEC-Q100 qualification status before substitution.
