SI8275DB-IS1

Isolators - Gate Drivers Overview

The SI8275DB-IS1 is a dual-channel galvanically isolated gate driver from Skyworks Solutions, designed for high-speed power switching applications. It features an isolation voltage of 2.5 kVrms and supports a supply voltage range of 4.2 V to 30 V. The device provides peak output currents of 1.8 A (high) and 4 A (low), with maximum propagation delays of 75 ns and pulse width distortion under 8 ns. Operating temperatures span from -40°C to +125°C, housed in a 16-SOIC package.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity ensures reliable signal transmission in noisy environments.
• Integrated undervoltage lockout protects against improper operation during low supply conditions.
• Deglitching circuitry filters out short-duration input spikes to prevent false triggering.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Switched-mode power supplies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1' corresponds to the required insulation and configuration parameters. Confirm that the 16-SOIC package matches the PCB footprint requirements. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the datasheet revision to confirm compatibility with existing design documentation.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed isolation with robust transient immunity is required. The dual-channel architecture allows for driving complementary switches or half-bridge configurations efficiently. Consider the 4 A peak current capability for driving medium-power MOSFETs or IGBTs without external amplification.

Isolators - Gate Drivers Part Context

This part belongs to the Si827x series of radio-frequency coupled isolators. These devices utilize Skyworks' proprietary capacitive coupling technology to provide electrical isolation between control and power domains. The series is optimized for industrial and automotive applications requiring high reliability and fast switching speeds.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same family include the SI8275DBD-IS1 variant, which offers identical electrical characteristics but utilizes a different surface-mount package format. Verify pin-to-pin compatibility before substitution.
