SI88422BD-ASR

Overview

The SI88422BD-ASR is a dual-channel digital isolator from Skyworks Solutions, featuring an integrated isolated DC-DC converter. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s with a typical propagation delay of 18 ns. The device provides 5000 Vrms isolation and functions across a temperature range of -40 °C to +125 °C. Packaged in a 16-pin SOIC, it includes two unidirectional reverse channels without forward channels or shutdown functionality.

Feature Summary

Integrates high-speed digital isolation with an on-chip isolated DC-DC converter for power delivery.
Utilizes silicon dioxide capacitive isolation barrier for robust signal transmission.
Features fully-integrated secondary sensing feedback controlled converter with dithering for low EMI.

Applications

Industrial automation systems
Hybrid electric and electric vehicles
Isolated power supplies

Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm package type and reel specifications. Ensure compatibility with required isolation ratings and thermal management strategies before finalizing component selection for production.

Selection Notes

Select this part when a compact solution combining dual-channel isolation and isolated power generation is required. Verify that the primary side input voltage does not exceed 5.5 V, as this model lacks external switch driver capabilities found in higher-voltage variants.

Part Context

This component belongs to the Si88x2x family, which integrates Skyworks' digital isolation technology with isolated DC-DC converters. The series offers various channel configurations and power options to support diverse industrial and automotive interface requirements.
