SI82E99AEE-IS3R

Isolators - Gate Drivers Overview

The SI82E99AEE-IS3R is a dual-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features silicon dioxide (SiO2) insulation technology providing a 6 kV RMS isolation rating and SELVCD certification. The device integrates high-side and low-side drivers in a 14-pin SOIC package. It operates with a supply voltage range of 3 V to 20 V for the input side and supports output voltages from 5 V to 30 V. Key electrical parameters include a maximum propagation delay of 40 ns, rise time of 8.3 ns, and fall time of 8.6 ns. It functions within a temperature range of -40°C to +125°C and consumes 2.04 mA of operating supply current.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 6 kV isolation rating meets the safety standards applicable to your target market, such as IEC 60747-17. Ensure the SOIC-14 footprint matches your PCB layout constraints and thermal management requirements before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a 6 kV isolation barrier is necessary between control logic and high-voltage power stages. The dual-channel architecture simplifies design by combining high-side and low-side driving capabilities. Consider the 40 ns propagation delay and 8.3/8.6 ns transition times for high-frequency operation needs. The wide operating temperature range supports deployment in demanding industrial environments without additional derating.

Isolators - Gate Drivers Part Context

This part belongs to the SI82E99 family of isolated gate drivers from Skyworks Solutions. These devices utilize proprietary SiO2 insulation technology, offering superior durability compared to traditional polymer or transformer-based isolators. The family is engineered for robust performance in harsh electromagnetic environments common in power electronics.

Isolators - Gate Drivers Replacement Considerations

Direct replacements must match the 6 kV isolation rating and dual-channel configuration. Verify pinout compatibility with the SOIC-14 package. Check if alternative models offer similar propagation delays and UVLO thresholds to ensure circuit stability during replacement scenarios.
