SI8274AB1-AM1

Isolators - Gate Drivers Overview

The SI8274AB1-AM1 is a dual-channel digital isolator gate driver from Skyworks Solutions, utilizing RF coupling technology for galvanic isolation. It features a 2500 Vrms isolation voltage and operates within a supply range of 4.2V to 30V on the output side. The device supports high-speed switching with typical rise and fall times of 10.5ns and 13.3ns, respectively. Maximum propagation delays are specified at 75ns (TPLH) and 60ns (TPHL). It provides peak output currents of 4A and functions reliably across an extended temperature range of -40°C to +125°C in a 14-LGA package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AM1 against official Skyworks documentation to confirm the 14-LGA package and dual-channel configuration. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the datasheet for exact pin assignments and recommended operating conditions before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with high peak current capability is required. The 4A output drives IGBTs or MOSFETs efficiently. Consider the 14-LGA package size for space-constrained designs. Verify that the 2500Vrms isolation rating meets your system's safety requirements and that the operating temperature range aligns with your environmental conditions.

Isolators - Gate Drivers Part Context

Part of the Si827x series of digital isolators, the SI8274AB1-AM1 leverages Skyworks' proprietary RF coupling technology. This series is designed for high-reliability applications where traditional optical isolators may fail due to aging or limited lifetime. The AM1 variant specifically targets automotive and industrial markets needing robust, long-lasting isolation solutions.

Isolators - Gate Drivers Replacement Considerations

Check for direct replacements within the Si827x family such as SI8274AB1-IS1 or SI8274AB1-AS1R if package differences are acceptable. Verify channel count and isolation voltage ratings match. Confirm availability status as some variants may be discontinued.
