SI88422ED-AS

Overview

The SI88422ED-AS is a dual-channel digital isolator from the Si88x2x family manufactured by Skyworks Solutions. It integrates an on-chip isolated DC-DC converter capable of delivering regulated output voltages of 3.3 V or 5.0 V, with peak power up to 5 W using external components. The device supports data rates up to 100 Mbps and features a typical propagation delay of 18 ns. It provides 5000 Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. The component utilizes capacitive coupling technology and is housed in a 16-pin SOIC-Wide package.

Feature Summary

Integrates a fully-controlled isolated DC-DC converter with secondary sensing feedback for low EMI.
Provides two unidirectional digital isolation channels with high-speed data transmission capabilities.
Features user-adjustable switching frequency and soft-start functionality for system safety.

Applications

Industrial automation systems
Hybrid electric and electric vehicles
Isolated power supplies

Procurement Notes

Verify the specific ordering suffix 'AS' against the manufacturer's official documentation to confirm pinout and feature configuration. Ensure that the required external transformer and passive components match the datasheet specifications for the intended input and output voltage levels. Confirm compliance with relevant safety certifications such as UL, CSA, and VDE for the final application design.

Selection Notes

Select this component when a combined solution for signal isolation and isolated power generation is required. The integrated DC-DC converter reduces the need for separate power supply components. Consider the 16-pin wide SOIC package for layout requirements and verify that the primary side voltage does not exceed the limits for the internal switch configuration.

Part Context

This part belongs to the Si88x2x series, which combines Skyworks' digital isolation technology with an integrated isolated DC-DC converter. The series offers options for different channel configurations and DC-DC features. The SI88422ED-AS specifically denotes a variant within this family designed for general-purpose isolation applications with integrated power conversion capabilities.
