SI8283DC-IS

Isolators - Gate Drivers Overview

The SI8283DC-IS is an automotive-grade, galvanically isolated gate driver designed for Silicon Carbide (SiC) and IGBT applications. It integrates a high-performance isolated DC-DC converter with a single-channel gate driver. The device features a 5000Vrms isolation voltage and a common-mode transient immunity of 35kV/µs. Key electrical parameters include a peak output current of 4A, propagation delays of 50ns maximum, and pulse width distortion of 5ns maximum. It operates within a supply voltage range of 2.8V to 5.5V and supports junction temperatures from -40°C to 125°C.

Isolators - Gate Drivers Feature Summary

• Integrates a robust isolated DC-DC converter to eliminate the need for external isolated power supplies.
• Provides high common-mode transient immunity suitable for noisy switching environments in power electronics.
• Optimized for driving wide-bandgap devices like SiC MOSFETs and traditional IGBTs with fast switching characteristics.

Isolators - Gate Drivers Applications

• Automotive traction inverters
• On-board chargers (OBC)
• DC-DC converters in electric vehicles

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' corresponds to the tape-and-reel packaging format when ordering. Confirm that the component meets AEC-Q100 automotive qualification requirements for your target application environment. Ensure compatibility with the required isolation voltage ratings and thermal management solutions for the final assembly.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with integrated isolated power is required for SiC or IGBT switches. Consider the 4A peak current capability and 50ns delay for high-frequency switching applications. Verify that the 24-SOIC package fits the PCB layout constraints and that the operating temperature range aligns with the system's thermal design.

Isolators - Gate Drivers Part Context

This part belongs to the Skyworks Si8283 series of automotive isolated gate drivers. The series is characterized by its integration of the isolated DC-DC converter, which simplifies system design compared to discrete isolation solutions. The 'DC' designation typically indicates the use of Skyworks' proprietary capacitive coupling technology for signal and power transmission across the isolation barrier.

Isolators - Gate Drivers Replacement Considerations

Direct replacements must be verified against the official Skyworks cross-reference list. Alternative parts should match the 24-SOIC package, 5000Vrms isolation rating, and integrated DC-DC functionality. Generic gate drivers without integrated isolation power are not direct substitutes due to additional BOM complexity.
