SI88622ED-ISR

Overview

The SI88622ED-ISR is a general-purpose digital isolator from Skyworks Solutions, featuring two unidirectional channels in a 20-SOIC package. It operates on a 3 V to 5.5 V supply with a typical propagation delay of 17.5 ns and rise/fall times of 2.5 ns. The device provides 5000 Vrms isolation and supports data rates up to 100 Mb/s. It exhibits a minimum common-mode transient immunity of 40 kV/µs and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Features integrated DC-DC converter for isolated power generation
• Supports high-speed digital signal transmission at 100 Mb/s
• Includes shutdown functionality for power management

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics interfaces for motor control applications
• General-purpose digital communication links across voltage domains

Procurement Notes

Verify the specific suffix 'ED' indicates the correct package width and pinout configuration for your PCB layout. Confirm that the integrated DC-DC converter requirement aligns with your system's power architecture. Ensure compatibility with the 20-SOIC footprint dimensions. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when bidirectional isolation is not required due to its unidirectional channel design. Consider the integrated DC-DC converter if isolated power is needed without external components. Evaluate the 40 kV/µs CMTI rating against noise environments. Compare thermal dissipation capabilities within the SOIC-20 package for your specific operating conditions.

Part Context

This part belongs to the Si8862x series of digital isolators designed for industrial applications. It complements other variants like the SI88622ED-IS which uses tube packaging instead of reel. The series emphasizes high reliability and low power consumption for demanding electronic environments.
