SI88422ED-ASR

Overview

The SI88422ED-ASR 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 capacitive coupling technology. The component is housed in a 16-pin SOIC package.

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 high common-mode transient immunity
Includes thermal protection and undervoltage lockout features for reliable operation

Applications

Industrial automation systems
Hybrid electric and electric vehicles
Isolated power supplies
Motor control circuits
Data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and feature set. Confirm that the required external transformer and passive components match the design guide specifications for the intended input and output voltage configuration. Ensure compliance with automotive qualification requirements if applicable to the target application environment.

Selection Notes

Select this component when a combined signal isolation and isolated power solution is required in a single package. Verify that the primary side input voltage exceeds 5.5 V, as this device is designed for high-voltage configurations requiring external power switches. Check that the system requires only two unidirectional channels and does not need bidirectional or shutdown functionality, which are available in other variants within the Si88x2x family.

Part Context

This part belongs to the Si88x2x family of dual digital isolators with integrated DC-DC converters. The 'ED' suffix typically denotes a wide-body SOIC package suitable for higher isolation ratings. The 'ASR' suffix indicates a reel packaging option. Other variants in the series may offer different channel counts, bidirectional capabilities, or internal switch configurations.
