SI88622ED-AS

Overview

The SI88622ED-AS is a dual-channel digital isolator from Skyworks Solutions, featuring an integrated isolated DC-DC converter. It provides two unidirectional data channels with a maximum data rate of 100 Mbps and a typical propagation delay of 18 ns. The device supports a supply voltage range of 3 V to 5.5 V and operates within a temperature range of -40°C to +125°C. It offers up to 5000 Vrms isolation voltage and utilizes SOIC-20 packaging.

Feature Summary

• Integrates a fully-controlled isolated DC-DC converter for power delivery across the isolation barrier
• Provides high-speed digital isolation with low propagation delay and jitter
• Includes safety features such as undervoltage lockout and thermal shutdown

Applications

• Industrial automation systems
• Hybrid electric and electric vehicles
• Isolated power supplies
• Motor control applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and electrical characteristics. Ensure compatibility with required isolation ratings and operating temperatures before integration into the design.

Selection Notes

Select this component when a combined signal isolation and isolated power solution is required in a single package. Consider the external transformer requirements and layout constraints associated with the integrated flyback converter topology.

Part Context

This part belongs to the Si88x2x family of dual digital isolators with integrated DC-DC converters. It shares architectural similarities with other members of the series but differs in channel configuration and specific pin assignments for the power stage controls.
