SI8284CC-IS

Isolators - Gate Drivers Overview

The SI8284CC-IS is a galvanically isolated gate driver from Skyworks Solutions, designed for SiC and IGBT applications. It features integrated DC-DC conversion, eliminating the need for external isolated power supplies. The device operates within a supply voltage range of 2.5 V to 5.5 V and delivers an output current of 84 mA with a peak capability of 4 A. Key electrical parameters include a maximum propagation delay of 50 ns, rise time of 5.5 ns, and fall time of 8.5 ns. It supports a maximum output voltage of 30 V and functions reliably between -40°C and +125°C. The component is housed in a 24-SOIC package and holds AEC-Q100 qualification.

Isolators - Gate Drivers Feature Summary

• Integrates a high-reliability DC-DC converter to provide isolated power, removing the requirement for separate isolated supply rails.

Isolators - Gate Drivers Applications

• Gate driving for Silicon Carbide (SiC) field-effect transistors
• Gate driving for Insulated Gate Bipolar Transistors (IGBTs)
• Industrial motor drive systems requiring high common-mode transient immunity

Isolators - Gate Drivers Procurement Notes

Verify that the specific part number suffix matches the required packaging configuration, as variations exist between tube and reel formats. Confirm that the procurement channel provides official Skyworks documentation to ensure authenticity. Check for AEC-Q100 certification status if automotive compliance is mandatory for the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with built-in power management is required. It is suitable for designs aiming to reduce bill-of-materials count by integrating the isolated supply. Consider the 24-SOIC footprint constraints and the 50 ns propagation delay limits against switching frequency requirements. Ensure the input logic levels are compatible with the CMOS interface specifications.

Isolators - Gate Drivers Part Context

This part belongs to the Si828x family of ISOdriver gate drivers, which utilize capacitive coupling technology for signal isolation. The series is engineered to replace traditional optocouplers in high-performance power electronics. The integration of the DC-DC converter distinguishes it from basic isolators, offering a complete solution for driving wide-bandgap semiconductors like SiC MOSFETs.
