SI8275ABD-IS1R

Isolators - Gate Drivers Overview

The SI8275ABD-IS1R is a dual-channel galvanically isolated gate driver from Skyworks Solutions, housed in a 16-SOIC package. It features high common-mode transient immunity of 200 kV/µs and an isolation voltage of 2500 Vrms. The device operates within a temperature range of -40°C to +125°C and includes a 5 V under-voltage lockout (UVLO). Key electrical parameters include a maximum propagation delay of 75 ns, with typical rise and fall times of 10.5 ns and 13.3 ns respectively. It delivers peak output currents of 1.8 A and 4 A for low-side and high-side channels.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against the manufacturer datasheet to confirm pinout configuration and UVLO thresholds. Ensure the 16-SOIC package dimensions match the target PCB footprint. Cross-reference the AEC-Q100 qualification status if automotive reliability standards are required for the end application.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with asymmetric drive strength is necessary. The 4A peak current capability suits medium-power switching devices. Consider the 75 ns delay limit for timing-sensitive topologies. Verify that the 2500 Vrms isolation rating meets the system's safety requirements.
