SI8274GA1-IM1

Isolators - Gate Drivers Overview

The SI8274GA1-IM1 is a single-channel digital isolated gate driver manufactured by Skyworks Solutions, Inc. It utilizes RF coupling technology to provide galvanic isolation with a rated voltage of 1000 Vrms. The device operates within an extended temperature range from -40°C to +125°C and features a maximum propagation delay of 75 ns. It supports a supply voltage range of 4.6 V to 30 V and delivers peak output currents up to 4 A. The component is housed in a 14-VDFN package.

Isolators - Gate Drivers Feature Summary

• Provides high-speed signal transmission via RF coupling technology for reliable data integrity
• Ensures electrical safety through robust galvanic isolation capabilities
• Supports wide operating supply voltage ranges for flexible system integration

Isolators - Gate Drivers Applications

• Industrial motor control systems requiring isolated gate driving
• Power conversion circuits needing high common-mode transient immunity
• Inverter and converter topologies utilizing insulated gate bipolar transistors or MOSFETs

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'GA1' against official Skyworks documentation to confirm the 1000 Vrms isolation rating, as other variants in the series may offer different insulation levels. Ensure the 'IM1' designation matches the required 14-VDFN surface-mount package configuration. Cross-reference the manufacturer part number directly with the latest datasheet to validate current availability status and any potential end-of-life notifications before finalizing procurement plans.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with 1000 Vrms isolation is required. Consider the 75 ns propagation delay and 4 A peak output current against load requirements. Compare against higher isolation variants like the GB1 series if system safety standards demand 2.5 kVrms. Evaluate the 14-VDFN footprint constraints against PCB layout limitations.

Isolators - Gate Drivers Part Context

This part belongs to the SI827x family of digital isolators, which leverage Skyworks' proprietary RF coupling technology. Unlike traditional optical couplers, these devices offer superior performance in terms of speed, reliability, and size. The SI8274 variant specifically provides dual-channel options, while the GA1 suffix denotes the single-channel configuration with 1000 Vrms isolation.
