SI8274GB1-IM1

Isolators - Gate Drivers Overview

The SI8274GB1-IM1 is a single-channel, galvanically isolated gate driver from Skyworks Solutions. It features a 14-pin QFN package and operates with a 2.5 kVrms isolation voltage. The device supports PWM input signals and includes a 3 V undervoltage lockout (UVLO). Key electrical parameters include a maximum propagation delay of 105 ns, a rise time of 16 ns, and a fall time of 18 ns. It delivers a peak output current of 4 A and dissipates up to 1.2 W of power. The component functions within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IM1' against official Skyworks documentation to confirm pinout and packaging details. Confirm that the 3 V UVLO specification aligns with target system requirements. Check for end-of-life notifications or alternative recommendations if long-term availability is critical. Ensure compliance with RoHS directives as indicated in manufacturer records.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with 3 V UVLO is required. Consider the 14-QFN package for space-constrained designs. Evaluate the 105 ns propagation delay against switching frequency needs. Compare against other Si827x variants if dual-channel or different UVLO thresholds are necessary.

Isolators - Gate Drivers Part Context

This part belongs to the Si827x family of digital isolators utilizing RF coupling technology. It provides high-speed data transmission across isolation barriers without optical components. The series is designed for applications demanding high reliability and fast switching speeds in electrically noisy environments.
