SI8282BC-ASR

Isolators - Gate Drivers Overview

The SI8282BC-ASR is an automotive-grade, galvanically isolated gate driver designed for Silicon Carbide (SiC) and IGBT applications. It integrates a high-voltage dc-dc converter to provide power across the isolation barrier without external components. The device features a single channel with both inverting and non-inverting outputs, supporting peak output currents of 4 A. It operates within a supply voltage range of 2.8 V to 5.5 V and delivers a maximum output voltage of 30 V. The component is qualified under AEC-Q100 standards and housed in a 20-pin SOIC package.

Isolators - Gate Drivers Feature Summary

• Integrated dc-dc converter eliminates need for external isolated power supply
• Capacitive coupling technology provides high reliability and immunity to magnetic fields
• Automotive qualification ensures compliance with rigorous reliability standards

Isolators - Gate Drivers Applications

• Silicon Carbide (SiC) transistor switching control
• Insulated Gate Bipolar Transistor (IGBT) gate drive
• Automotive power electronics systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix ASR indicates reel packaging configuration. Confirm that the BC variant corresponds to the intended pinout and functional configuration for your design. Ensure the supplier source is authorized to guarantee authenticity given the automotive grade requirements. Check current availability status as distribution may be restricted.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with integrated power generation is required for SiC or IGBT switches. The integrated dc-dc simplifies board layout by removing auxiliary transformer requirements. Consider the 4 A peak current capability for driving medium-power devices. Verify thermal management needs for the SOIC-20 package under continuous operation conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Skyworks Si8282 series of automotive isolated gate drivers. It complements other variants like the SI8283 and SI8284 which offer different channel counts or configurations. The series utilizes Skyworks' proprietary capacitive isolation technology for robust signal transmission across high potential differences in electric vehicle and industrial power applications.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other Skyworks Si828x series parts such as SI8283 or SI8284 if channel count differs. Cross-brand replacements require matching isolation voltage, peak current, and package dimensions. Verify that alternative drivers support the same integrated dc-dc functionality to maintain system architecture simplicity.
