SI82394AD4-IS

Isolators - Gate Drivers Overview

The SI82394AD4-IS is a galvanically isolated gate driver from the Si8239x series, manufactured by Skyworks Solutions. It features a 16-pin SOIC-Wide package and supports two channels with non-inverting logic configuration. The device operates within a temperature range of -40°C to +125°C and has a maximum power dissipation of 2.1 W. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns each, and an insulation voltage of 2500 Vrms. It utilizes TTL logic inputs.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation for high-speed signal transmission between control and power stages.
• Features high electromagnetic immunity suitable for noisy industrial environments.
• Includes undervoltage lockout (UVLO) functionality to ensure reliable operation.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• High-voltage switching applications

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' against official Skyworks documentation to confirm the exact insulation rating and package variant, as datasheets may list variations such as IS3 or AS3 with different insulation voltages like 3250 Vrms. Ensure the component meets AEC-Q100 requirements if automotive qualification is needed, noting that some variants in this family carry this certification while others may not.

Isolators - Gate Drivers Selection Notes

Select this component when a 16-pin wide SOIC package is required for thermal or layout reasons compared to narrower packages. Consider the 2500 Vrms insulation rating against system safety standards. Evaluate the 40 ns propagation delay and 12 ns transition times against the switching frequency requirements of the target power devices. Confirm compatibility with 2.5 V to 5.5 V input logic levels.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of digital isolators and gate drivers. The family offers various channel counts and package options, including 14-pin and 16-pin configurations. The AD4 designation typically indicates a specific pinout and feature set within this series, designed for robust isolation in power electronics.

Isolators - Gate Drivers Replacement Considerations

Check for SI82394AD4-IS3 or SI82394BD4-IS as potential alternatives, but verify differences in insulation voltage (e.g., 3250 Vrms vs 2500 Vrms) and package type (SOIC-14 vs SOIC-16). Ensure any substitute maintains the same channel count and logic configuration.
