SI8275GB-IS1

Isolators - Gate Drivers Overview

The SI8275GB-IS1 is a dual-channel, galvanically isolated gate driver from the Si827x series by Skyworks Solutions. It utilizes RF coupling technology to provide high common-mode transient immunity (CMTI) and operates with a 2.5 kVrms isolation voltage. The device features a 3 V UVLO threshold and supports output supply voltages between 4.2 V and 30 V. It delivers peak output currents of up to 4 A with propagation delays of 75 ns maximum. Designed for surface-mount installation in SOIC-8 packages, it functions within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity utilizing RF coupling technology

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1 against official Skyworks documentation to confirm package type and tape/reel specifications. Ensure compatibility with system isolation requirements and thermal management needs before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Isolators - Gate Drivers Selection Notes

Select this component when high CMTI and robust isolation are required for driving power switches. Compare channel count and isolation voltage against alternatives like the SI8271 series if lower voltage ratings suffice. Evaluate the 3 V UVLO threshold against input logic levels to ensure proper signal integrity during startup conditions.
