SI82394AB4-IS1R

Isolators - Gate Drivers Overview

The SI82394AB4-IS1R is a dual-channel, galvanically isolated gate driver from the Si8239x series by Skyworks Solutions. It features capacitive coupling technology for high electromagnetic immunity and operates within an industrial temperature range of -40°C to +125°C. The device provides a peak output current of 4 A with a maximum propagation delay of 40 ns and rise/fall times of 12 ns. It utilizes a 16-pin SOIC-Narrow package and supports non-inverting logic configuration. Key electrical parameters include a 2500 Vrms isolation voltage, 5.5 V maximum input voltage, and a 6 V under-voltage lockout (UVLO) threshold.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling architecture ensures high common-mode transient immunity
• Dual-channel design supports high-side and low-side switching applications
• Industrial-grade reliability with AEC-Q100 qualification

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Power supply control circuits

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against official Skyworks documentation to confirm tape-and-reel packaging and exact UVLO thresholds. Ensure compatibility with system isolation requirements and thermal management needs for the SOIC-Narrow package. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring robust isolation in noisy environments. The 4 A drive strength suits medium-power MOSFETs and IGBTs. Consider the 6 V UVLO setting when designing gate drive loops. Verify that the 16-pin footprint matches the PCB layout constraints and that the operating temperature range meets environmental specifications.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It shares core architectural features with other variants in the series but differs in packaging and specific electrical thresholds. The 'IS1R' designation indicates a reel-packaged version of the standard IS1 variant, maintaining identical functional characteristics while altering logistics handling.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks datasheets for direct pin-compatible alternatives within the Si8239x family. Verify if other suffixes offer different UVLO levels or packaging options suitable for the application.
