SI82398CD4-AS

Isolators - Gate Drivers Overview

The SI82398CD4-AS is a dual-channel digital isolator gate driver from Skyworks Solutions, designed for automotive applications. It features capacitive coupling technology providing 2500 Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. The device delivers a peak output current of 4A with a maximum propagation delay of 40 ns. It utilizes a 16-SOIC package and includes an undervoltage lockout (UVLO) threshold of 12V.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling architecture ensures high electromagnetic immunity and reliable signal transmission across the isolation barrier.
• Automotive-grade qualification supports deployment in demanding vehicle electronic environments.
• Integrated UVLO mechanism protects connected power devices by preventing operation during insufficient supply conditions.

Isolators - Gate Drivers Applications

• Automotive motor control systems
• High-voltage power conversion circuits
• Industrial inverter drives

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm automotive grade status and pinout compatibility. Ensure the 12V UVLO threshold aligns with your system's power rail requirements before integration. Cross-reference the SOIC-16 footprint dimensions with your PCB layout guidelines to guarantee mechanical fit.

Isolators - Gate Drivers Selection Notes

Select this component when automotive reliability and high-speed switching are required. The 12V UVLO setting suits systems where the gate drive supply remains stable above this threshold. Consider the 4A peak current capability for driving medium-power MOSFETs or IGBTs efficiently without external buffering.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It shares core architectural traits with other variants but differs in UVLO thresholds and packaging options. The CD4-AS designation specifically indicates the wide-body SOIC package and automotive qualification level within the broader product line.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include SI82398BD4-IS and SI82398AD-IS, provided their respective UVLO thresholds (8V and 6V) match the application needs. Verify that the alternative part maintains the same 16-SOIC package and 4A output current capability to ensure electrical compatibility.
