SI82398AD-IS

Isolators - Gate Drivers Overview

The SI82398AD-IS is a dual-channel, galvanically isolated gate driver from the Si8239x series by Skyworks Solutions. It features capacitive coupling technology with a 5000 Vrms isolation voltage and operates within a -40°C to +125°C temperature range. The device provides non-inverting logic configuration in a 16-SOIC package. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns, and a peak output current of 4 A. It supports a supply voltage range of 6.5 V to 24 V with a 6 V UVLO threshold.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology for high electromagnetic immunity
• Dual-channel configuration with independent high-side and low-side drivers
• Non-inverting logic input configuration
• Automotive qualification under AEC-Q100 standards

Isolators - Gate Drivers Applications

• Industrial motor control systems
• Automotive power electronics
• High-voltage switching applications requiring galvanic isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' corresponds to the standard tube packaging variant rather than reel options like 'ISR'. Confirm that the 6 V UVLO specification matches the target circuit requirements. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for RoHS compliance status as indicated in official documentation before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 5 kVrms isolation is required. The 4 A peak current capability suits medium-power MOSFET or IGBT driving. The 6 V UVLO setting is suitable for lower gate drive voltage applications compared to 8 V or 12 V variants. Consider the 16-SOIC package width for thermal and spacing constraints in dense layouts.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It shares core specifications with other variants like SI82398BD-IS but differs in undervoltage lockout thresholds and specific insulation ratings. The 'AD' designation typically indicates specific pinout or feature sets within the broader product line.

Isolators - Gate Drivers Replacement Considerations

SI82398BD-IS offers similar functionality with an 8 V UVLO threshold. SI82398CB4-IS1 provides a 12 V UVLO option. Verify pinout compatibility and isolation voltage requirements when substituting these related parts.
