SI82394CD-IS3R

Isolators - Gate Drivers Overview

The SI82394CD-IS3R is a dual-channel galvanically isolated gate driver from Skyworks Solutions, designed for high-speed switching applications. It features a 12 V under-voltage lockout (UVLO) and operates within an extended temperature range of -40 °C to +125 °C. The device provides a maximum propagation delay of 40 ns, with rise and fall times of 12 ns each. It supports a peak output current of 4 A and delivers an output voltage of 8 V. The component is housed in a 14-pin SOIC-Wide package and offers an insulation voltage of 3250 Vrms. Power dissipation is rated at 2.1 W, and it meets AEC-Q100 automotive qualification standards.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology enables high electromagnetic immunity and reliable signal isolation.
• Dual-channel configuration supports independent control of high-side and low-side switches.
• Automotive-grade qualification ensures reliability in demanding operating environments.

Isolators - Gate Drivers Applications

• Motor drive systems requiring isolated gate control
• Inverter circuits in electric vehicle powertrains
• Industrial motor controllers needing high noise immunity

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R corresponds to the reel packaging format as indicated in distributor listings. Confirm that the 12 V UVLO variant matches the system requirements, distinguishing it from other variants like the BD series which may feature different UVLO thresholds or pinouts. Ensure the SOIC-Wide-14 footprint aligns with the PCB design guidelines provided in the official datasheet.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 12 V UVLO is required for automotive or industrial applications. Compare against the SI82397CD-IS3R if identical electrical characteristics are needed but different ordering suffixes apply. Consider the SI82394BD4-AS if an 8 V UVLO threshold or tube packaging is preferred instead of the reel format associated with the IS3R suffix.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of capacitive isolators, which utilize Skyworks' proprietary iCoupler technology. The family includes various configurations differing by channel count, UVLO levels, and packaging options. The SI82394CD-IS3R specifically targets applications requiring robust isolation with fast switching speeds and automotive certification.

Isolators - Gate Drivers Replacement Considerations

The SI82397CD-IS3R is a confirmed substitute within the same series offering similar electrical performance. Other members of the Si8239x family may serve as alternatives depending on specific UVLO and packaging requirements.
