SI82394CD-ISR

Isolators - Gate Drivers Overview

The SI82394CD-ISR is a dual-channel digital isolator gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features capacitive coupling technology to provide galvanic isolation between input and output circuits. The device operates within a supply voltage range of 2.5 V to 5.5 V on the input side and supports up to 12 V on the output side. It delivers a peak output current of 4 A with a maximum propagation delay of 40 ns. The component is housed in a 16-SOIC package and offers an insulation voltage rating of 5000 Vrms.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling provides robust electromagnetic immunity
• Dual-channel configuration for independent control
• High peak output current capability for efficient switching

Isolators - Gate Drivers Applications

• Industrial motor drives
• Power supply inverters
• Isolated DC/DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ISR' corresponds to the tape-and-reel packaging variant rather than tube packaging when sourcing. Confirm that the 5000 Vrms insulation rating aligns with system safety requirements. Ensure the SOIC-16 footprint matches the PCB layout constraints. Cross-reference the operating temperature range with environmental conditions.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring high-speed switching with strong noise immunity. The dual-channel design simplifies circuit topology for half-bridge or full-bridge configurations. Consider the 4 A drive strength for medium-power MOSFETs or IGBTs. Verify compatibility with standard logic levels for the control interface.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It utilizes Skyworks' proprietary capacitive isolation technology. The series is known for high reliability and low skew characteristics. It serves as a bridge between low-voltage control logic and high-voltage power stages.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include SI82394BD-IS and SI82394CD-IS. Check if the alternative package type (tube vs. reel) meets assembly needs. Verify that the insulation voltage and channel count remain identical for functional equivalence.
