SI82397AD-IS

Isolators - Gate Drivers Overview

The SI82397AD-IS is a dual-channel galvanically isolated gate driver from Skyworks Solutions, housed in a 16-pin SOIC-Wide package. It features a 5 kVrms isolation voltage and a 6 V undervoltage lockout (UVLO). The device supports a supply voltage range of 5.5 V to 30 V and delivers peak output currents of 4 A. Key electrical parameters include a maximum propagation delay of 40 ns, with rise and fall times of 12 ns each. It operates within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm pinout and functional variations. Ensure compatibility with your system's isolation requirements and thermal management strategy. Cross-reference the datasheet for exact operating conditions and derating curves before finalizing component selection for production.

Isolators - Gate Drivers Selection Notes

Select this component when high-voltage isolation and fast switching speeds are required for dual-MOSFET applications. Consider the 16-pin SOIC-Wide package for PCB layout constraints and thermal dissipation needs. Verify that the 6 V UVLO threshold aligns with your gate drive logic levels and supply voltage stability.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of digital isolators designed for power switching applications. It combines two independent channels in a single package to reduce board space. The series is engineered for reliability in harsh environments, featuring silicon dioxide isolation technology for long-term performance and safety compliance.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si8239x family, such as variants with different UVLO thresholds or isolation ratings. Ensure any replacement maintains the same 16-pin SOIC-Wide footprint and electrical characteristics to avoid redesigning the PCB layout or power stage.
