• Industrial inverter drives
• High-side and low-side gate driving

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'C' against official Skyworks documentation to confirm pinout and electrical characteristics, as suffixes often denote package or revision differences. Confirm availability status directly with the manufacturer or authorized distributors, as this part number may be subject to lifecycle changes or limited stock constraints.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with high CMTI is required for automotive-grade reliability. Ensure the input voltage range matches the control logic and that the SOIC-Wide-16 footprint fits the PCB layout. Verify thermal dissipation requirements given the operating temperature range and power dissipation specifications.

Isolators - Gate Drivers Part Context

This device belongs to the Si823x series of isolated gate drivers from Skyworks Solutions. The series is characterized by its use of silicon dioxide-based capacitive isolation technology, offering robust performance in high-voltage switching applications while maintaining small form factors and low power consumption compared to traditional magnetic isolators.

Isolators - Gate Drivers Replacement Considerations

Official direct replacements include the SI8235BB-D-IS. Verify functional equivalence regarding pinout and electrical parameters before substitution. Other variants in the Si823x family may serve as alternatives if specific suffix requirements differ.
