SI8275ABD-IM1R

Isolators - Gate Drivers Overview

The SI8275ABD-IM1R is a dual-channel galvanically isolated gate driver from Skyworks Solutions, utilizing radio frequency (RF) coupling technology. It features a peak output current of 4A and supports an output supply voltage range of 4.2V to 30V. The device provides 2500Vrms isolation voltage with a minimum common-mode transient immunity of 200kV/µs. Propagation delays are limited to 75ns for both high-to-low and low-to-high transitions, with pulse width distortion under 8ns. Typical rise and fall times are 10.5ns and 13.3ns respectively. It operates within a temperature range of -40°C to 125°C and is housed in a 14-QFN (5x5) package.

Isolators - Gate Drivers Feature Summary

• Employs RF capacitive coupling technology for high-speed signal transmission across the isolation barrier.
• Delivers robust common-mode transient immunity to ensure reliable operation in electrically noisy environments.
• Provides independent control for two separate channels with optimized propagation delay matching.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Power supply gate driving

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IM1R' corresponds to the tape-and-reel packaging configuration as indicated by official documentation. Confirm that the component meets required safety certifications such as UL, CSA, VDE, or CQC for the intended application region. Ensure compatibility with the specified 14-QFN footprint during PCB layout review.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching and strong noise immunity are critical requirements. The dual-channel architecture allows for efficient half-bridge or full-bridge configurations. Consider the 4A peak drive capability for driving medium-power MOSFETs or IGBTs without external amplification.
