SI82394BB4-IS1R

Isolators - Gate Drivers Overview

The SI82394BB4-IS1R is a dual-channel galvanically isolated gate driver from the Si8239x series, manufactured by Skyworks Solutions. It features a 16-lead SOIC-Narrow package and provides 2500 Vrms isolation voltage. The device operates within a temperature range of -40°C to +125°C and supports AEC-Q100 qualification for automotive applications. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns, and an output current capability of 4 A. It utilizes non-inverting TTL logic configuration with an 8 V UVLO threshold.

Isolators - Gate Drivers Feature Summary

• Provides high electromagnetic immunity suitable for industrial environments
• Features integrated undervoltage lockout (UVLO) protection
• Supports automotive reliability standards through AEC-Q100 qualification

Isolators - Gate Drivers Applications

• Automotive power electronics systems
• Industrial motor control drives
• High-frequency switching power supplies

Isolators - Gate Drivers Procurement Notes

Verify that the specific suffix 'IS1R' corresponds to the tape-and-reel packaging variant rather than the tube-packaged 'IS1'. Confirm the 8V UVLO specification matches system requirements, distinguishing it from other variants like the CB4-IS1 which utilizes a 12V threshold. Ensure compatibility with the SI8239XISO-KIT development environment if applicable.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated gate driver with 2500 Vrms isolation and 4 A peak drive current is required. The 8V UVLO setting is critical for specific low-voltage gate drive applications. Consider the SOIC-Narrow package dimensions and the 40 ns propagation delay for timing-sensitive designs in automotive or industrial contexts.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of digital isolator gate drivers. It shares core specifications such as channel count, isolation voltage, and package type with siblings like the SI82394CB4-IS1, differing primarily in the UVLO threshold configuration and packaging format.

Isolators - Gate Drivers Replacement Considerations

The SI82394CB4-IS1 serves as a functional alternative within the same series but differs by utilizing a 12V UVLO threshold instead of 8V. Verify that the higher threshold does not conflict with the target gate drive voltage levels before substitution.
