SI88441EC-IS

Digital Isolators Overview

The SI88441EC-IS is a Skyworks Solutions digital isolator featuring four channels with integrated DC-DC converter capability. It utilizes capacitive coupling technology to provide an isolation voltage of 3750 Vrms. The device supports unidirectional signal transmission at data rates up to 100 Mb/s, with a propagation delay of 18 ns and rise/fall times of 2.5 ns. It operates within a supply voltage range of 3 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a SOIC-Wide-20 format, it meets AEC-Q100 automotive qualification standards.

Digital Isolators Feature Summary

• Provides robust capacitive coupling isolation rated at 3750 Vrms for enhanced safety
• Features low propagation delay and fast transition times for high-frequency signal integrity
• Automotive qualified under AEC-Q100 standards for reliable operation in demanding environments

Digital Isolators Applications

• Automotive powertrain and battery management systems
• Industrial motor control and drive applications
• Grid infrastructure and renewable energy inverters
• Medical equipment requiring high isolation barriers

Digital Isolators Procurement Notes

Verify the specific suffix 'EC' confirms the 3750 Vrms insulation rating and SOIC-Wide-20 package variant. Confirm AEC-Q100 qualification status if automotive compliance is required. Check manufacturer lifecycle status as some related variants may be NRND. Ensure compatibility with si88xxxiso-kit development tools for validation.

Digital Isolators Selection Notes

Select this component when a 3750 Vrms isolation barrier is sufficient compared to higher-rated 5 kV variants. The integrated DC-DC converter reduces external component count. Consider the SOIC-Wide-20 package for thermal performance and board space. Verify channel configuration matches the application's directional signal requirements.
