Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS1R corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the wide-body SOIC-16 footprint matches the target PCB layout dimensions. Ensure the selected variant meets the necessary AEC-Q100 qualification standards if deployed in automotive-grade applications requiring strict reliability certifications.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with a wide-body package is required for enhanced creepage distances. Compare against other Si823Hx variants based on insulation voltage ratings and channel count. Consider the non-inverting logic requirement and the specific propagation delay characteristics relative to the switching frequency needs of the power stage design.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers, which utilizes Skyworks' proprietary capacitive isolation technology. The family offers various configurations including single and dual channels with different insulation voltages and package options. The wide-body SOIC-16 package distinguishes this model by providing increased physical spacing for high-voltage isolation requirements.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si823Hx family such as SI823H1BD or SI823H9AC, ensuring pinout compatibility and matching isolation voltage ratings. Verify that alternative components support the same SOIC-16 wide-body footprint and meet the required automotive temperature specifications.
