SI82F99EEE-IS3

Isolators - Gate Drivers Overview

The SI82F99EEE-IS3 is a dual-channel isolated gate driver from Skyworks Solutions, featuring Silicon Dioxide (SiO2) isolation technology. It provides 6 kV RMS isolation voltage and integrates Self-Voltage Detection (SelVCD) for enhanced safety. The device supports high-side and low-side configurations with Miller clamp functionality to prevent false turn-on. It operates within a supply voltage range of 3 V to 20 V and delivers an output current of 4 A. Packaged in a SOIC-14 surface-mount format, it ensures reliable signal transmission across isolated boundaries.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'EEE' against the manufacturer's latest datasheet to confirm pinout and package dimensions, as ordering codes define physical attributes. Ensure compliance with RoHS directives and check for automotive qualification status if applicable to the target application environment. Confirm availability through authorized distributors due to potential supply constraints.

Isolators - Gate Drivers Selection Notes

Select this component when 6 kV isolation is required alongside active Miller clamp protection. The SelVCD feature distinguishes it from standard drivers by detecting open-circuit conditions. Compare channel count and output current capabilities against load requirements. Consider the SOIC-14 footprint for PCB layout constraints relative to alternative packages.

Isolators - Gate Drivers Part Context

This part belongs to the Si82Fx family of isolated gate drivers designed for high-reliability power electronics. The series emphasizes durability through SiO2 insulation, offering superior performance over traditional polymer or air gap technologies. It targets applications demanding strict safety standards and precise timing control in high-frequency switching environments.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same family include variants with different UVLO thresholds or isolation ratings, such as the SI82F97 or SI82F98 series, provided they match the 6 kV requirement and SOIC-14 package. Cross-family replacements require verification of pin compatibility and isolation voltage levels.
