SI8452AB-A-IS1

Overview

The SI8452AB-A-IS1 is a general-purpose digital isolator from Skyworks Solutions, featuring five channels with three forward and two reverse unidirectional paths. It utilizes capacitive coupling technology to provide galvanic isolation with a voltage rating of 2500 Vrms. The device supports data rates up to 1 Mbps and operates within a supply voltage range of 2.7 V to 5.5 V. It offers a propagation delay of 35 ns and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Features a mixed channel configuration with three forward and two reverse unidirectional paths
• Includes a shutdown function for power management control

Applications

• General purpose digital isolation in industrial systems
• Isolation for sensor interfaces requiring low data rates
• Power electronics control circuit isolation

Procurement Notes

Verify the specific datasheet version for the SI8452AB-A-IS1, as product attributes such as insulation voltage and data rate may vary significantly from similar model numbers like the SI8452BA series. Confirm that the 2500 Vrms isolation rating and 1 Mbps speed match your design requirements before procurement.

Selection Notes

Select this component when a mixed directionality configuration (3 forward, 2 reverse) is required alongside moderate isolation voltage. Ensure the 1 Mbps data rate suffices for the application, as higher-speed variants exist within the same package family. Verify compatibility with the 2.7 V to 5.5 V logic levels.

Part Context

This part belongs to the SI8452BA/AA/AB series of digital isolators. It shares the SOIC-Narrow-16 package and basic operational principles with other members but differs in isolation voltage ratings and channel configurations. It is distinct from the SI8452BA series which typically offers higher data rates and different isolation voltages.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Skyworks resources for current alternatives or obsolescence notices.
