SI8283EC-ASR

Isolators - Gate Drivers Overview

The SI8283EC-ASR is an automotive-grade, galvanically isolated gate driver designed for Silicon Carbide (SiC) and IGBT power devices. It integrates a high-voltage DC-DC converter to provide isolated power, eliminating the need for external isolated supplies. The device features a single-channel output with inverting or non-inverting logic options. It operates within an extended temperature range of -40°C to +125°C and is housed in a 24-pin Wide Body SOIC package. The component meets AEC-Q100 qualification standards for automotive reliability.

Isolators - Gate Drivers Feature Summary

• Integrated isolated DC-DC converter eliminates requirement for external isolated power supply
• High voltage isolation capability suitable for SiC and IGBT switching applications
• Automotive grade construction compliant with AEC-Q100 reliability standards

Isolators - Gate Drivers Applications

• Isolated gate driving for Silicon Carbide (SiC) MOSFETs in electric vehicle inverters
• Gate drive stages for Insulated Gate Bipolar Transistors (IGBTs) in industrial motor drives
• High-frequency switching circuits requiring robust galvanic isolation between control and power domains

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ASR' corresponds to the required tape-and-reel packaging configuration during procurement. Confirm that the ECAD model matches the physical footprint of the 24-SOIC package for accurate PCB layout integration. Ensure design compliance with the specified operating temperature range and isolation voltage ratings for the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when an integrated isolated power solution is required for high-power semiconductor switching. It is appropriate for designs needing simplified bill of materials by removing discrete isolated supply components. Consider its automotive qualification if the end product requires AEC-Q100 compliance. Evaluate the single-channel architecture against system channel count requirements before finalizing the selection.

Isolators - Gate Drivers Part Context

This part belongs to the Skyworks Si8283 family of automotive isolated gate drivers. The family shares core technology but varies in packaging and pinout configurations. The SI8283EC-ASR specifically denotes the version packaged in reels for automated assembly processes, distinguishing it from tube-packaged variants within the same functional series.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other Skyworks Si8283 variants such as SI8283ED-ASR or SI8283EC-AS, provided the packaging format and electrical characteristics align with the existing design constraints. Cross-manufacturer replacements require careful verification of isolation voltage, propagation delay, and peak current drive capabilities.
