SI88442BC-AS

Isolators - Gate Drivers Overview

The SI88442BC-AS is a digital isolator manufactured by Skyworks Solutions Inc., designed for general-purpose applications. It features four channels with two forward and two reverse paths, operating in a unidirectional polarity configuration without a shutdown function. The device supports data rates up to 100 Mb/s and provides an insulation voltage of 5000 Vrms. It operates within a supply voltage range of 3 V to 5.5 V, exhibiting a maximum propagation delay of 18 ns and rise/fall times of 2.5 ns. The component is housed in a SOIC-20 package, suitable for surface mount installation, and functions reliably across temperatures from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation with high common-mode transient immunity capabilities
• Supports bidirectional signal transmission through dedicated forward and reverse channel pairs
• Operates with low pulse width distortion for precise timing integrity

Isolators - Gate Drivers Applications

• Industrial automation control systems requiring isolated signal interfaces
• Power electronics monitoring circuits needing high-voltage isolation
• General-purpose digital communication links between isolated domains

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm pinout and electrical characteristics match project requirements. Ensure compliance with RoHS standards and moisture sensitivity levels during storage and reflow processes. Cross-reference the SOIC-20 footprint dimensions with PCB layout guidelines to prevent assembly errors. Confirm that the unidirectional polarity specification aligns with the intended signal flow direction in the target circuit design.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed digital isolation is required alongside robust thermal performance. The 100 Mb/s data rate suits moderate-speed communication protocols. Consider the 5000 Vrms insulation rating for safety-critical applications. The absence of a shutdown feature simplifies logic but requires careful power sequencing. Evaluate the SOIC-20 package size constraints relative to available board space and thermal dissipation needs.
