SI8283CD-IS

Isolators - Gate Drivers Overview

The SI8283CD-IS is a single-channel, galvanically isolated gate driver from Skyworks Solutions Inc., designed for driving SiC and IGBT power devices. It utilizes capacitive coupling technology to provide high-voltage isolation with an integrated DC-DC converter. The device operates within a supply voltage range of 2.5 V to 5.5 V on the logic side and supports output voltages up to 30 V. Key electrical parameters include a peak output current of 4 A, a propagation delay of 50 ns, and rise/fall times of 10.5 ns and 13.3 ns respectively. It features AEC-Q100 qualification and operates between -40°C and +125°C in a 24-SOIC package.

Isolators - Gate Drivers Feature Summary

• Integrates a high-reliability DC-DC converter for robust isolated power delivery without external components.
• Provides high common-mode transient immunity (CMTI) suitable for noisy switching environments.
• Supports both inverting and non-inverting logic configurations for flexible control interface integration.

Isolators - Gate Drivers Applications

• Gate driving for Silicon Carbide (SiC) MOSFETs in high-frequency power converters.
• Isolated control interfaces for Insulated Gate Bipolar Transistors (IGBTs).
• Automotive traction inverters and onboard chargers requiring AEC-Q100 compliance.

Isolators - Gate Drivers Procurement Notes

Verify that the specific suffix 'IS' corresponds to the standard SOIC-24 package variant rather than the reel-based 'ISR' version if tube packaging is required. Confirm that the integrated DC-DC converter specifications meet the target load requirements. Ensure input signal levels are compatible with the specified logic voltage range before implementation.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with an internal power source is needed for SiC or IGBT applications. It is appropriate for designs prioritizing high CMTI and automotive reliability over multi-channel integration. Compare against the SI8281 series if lower output current is sufficient, or the SI8282 series if different pinout compatibility is required.
