SI8282DC-AS

Isolators - Gate Drivers Overview

The SI8282DC-AS is an automotive-grade, galvanically isolated gate driver designed for Silicon Carbide (SiC) and IGBT applications. It integrates a high-performance 4 A driver with a robust 2 W DC-DC converter, eliminating the need for external isolated power supplies. The device utilizes Skyworks' ISOdriver technology for reliable signal transmission across the isolation barrier. Key electrical characteristics include a peak output current of 4 A and a breakdown voltage supporting high-voltage switching environments.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AS' to confirm automotive grade qualification and tape-and-reel packaging configuration. Ensure the procurement source provides valid RoHS compliance documentation and original manufacturer traceability. Cross-reference the full part number against official Skyworks distribution channels to avoid counterfeit components, as availability may vary by region.

Isolators - Gate Drivers Selection Notes

Select this component when designing systems requiring integrated isolated power and high-current driving for wide-bandgap semiconductors. It is suitable for applications where board space is limited due to the elimination of external isolated supply requirements. Consider the thermal performance and package type relative to the system's heat dissipation capabilities.

Isolators - Gate Drivers Part Context

This device belongs to the Si828x ISOdriver family from Skyworks Solutions. The series focuses on providing compact, high-reliability solutions for power electronics. The SI8282 variant specifically targets high-current applications, distinguishing itself from lower-output models within the same product line through its enhanced drive strength and integrated power stage.

Isolators - Gate Drivers Replacement Considerations

Direct replacements must match the 4 A output current and integrated DC-DC specifications. Verify pinout compatibility and isolation voltage ratings before substitution. Consult Skyworks documentation for updated equivalents within the ISOdriver portfolio.
