SI88220BD-IS

Digital Isolators Overview

The SI88220BD-IS is a unidirectional digital isolator featuring two channels with integrated DC-DC converters. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an isolation voltage of 5000 Vrms using capacitive coupling technology. Key electrical parameters include a propagation delay of 18 ns, rise and fall times of 2.5 ns, and a pulse width distortion of 7 ns. It functions reliably across a temperature range of -40°C to +125°C and is housed in a SOIC-Wide-16 package.

Digital Isolators Feature Summary

• Integrates a 2W DC-DC converter for isolated power generation
• Utilizes capacitive coupling for high reliability and noise immunity
• Supports unidirectional signal transmission with dual channels

Digital Isolators Applications

• Industrial automation systems requiring robust signal isolation
• Power electronics applications involving high-voltage switching
• Motor drive circuits needing reliable gate driver isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' corresponds to the tube packaging format rather than reel variants. Confirm that the component meets AEC-Q100 qualification requirements if automotive compliance is necessary for the target application. Ensure the design accounts for the integrated DC-DC converter's power delivery capabilities during system integration.

Digital Isolators Selection Notes

Select this component when high isolation voltage and integrated power conversion are required in a compact form factor. The unidirectional nature suits applications where signal flow is strictly one-way. Consider the SOIC-Wide-16 package for thermal management and ease of PCB layout compared to smaller packages.

Digital Isolators Part Context
