SI86S620EE-AS4

Digital Isolators Overview

The SI86S620EE-AS4 is a Skyworks Solutions automotive-grade digital isolator featuring two unidirectional channels with an inverting output configuration. It utilizes capacitive coupling technology to provide robust signal isolation rated at 6.0 kVrms. The device operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical specifications include a propagation delay of 13 ns, with rise and fall times of 2.5 ns maximum. It offers a pulse width distortion of 3.5 ns and a minimum pulse width capability of 6.7 ns. The component is housed in an SSO-8 package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• High-voltage isolation via capacitive coupling technology
• Inverting output logic configuration for signal inversion
• Unidirectional channel design for specific signal flow requirements

Digital Isolators Applications

• Automotive electronic control units (ECUs)
• Electric vehicle battery management systems
• Automotive sensor interface circuits
• Vehicle communication bus isolation

Digital Isolators Procurement Notes

Verify the exact suffix AS4 against official Skyworks documentation to confirm packaging and tape-and-reel specifications. Ensure the inverting output characteristic aligns with system logic requirements. Confirm AEC-Q100 compliance status through current datasheets. Validate that the SSO-8 footprint matches the target PCB layout constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high-voltage isolation is required for automotive environments. The inverting output feature necessitates consideration of downstream logic levels. Verify that the 150 Mb/s data rate suffices for the application's bandwidth needs. Ensure the 6.0 kVrms isolation rating meets safety standards. Compare against non-inverting variants if signal polarity preservation is critical.

Digital Isolators Part Context

This part belongs to the Si86S6x series of digital isolators from Skyworks Solutions. It shares the core capacitive isolation architecture with other models in the family but differs in its specific automotive qualification, inverting output configuration, and 6.0 kVrms isolation rating. It complements lower-voltage or bidirectional variants within the broader interface IC portfolio.

Digital Isolators Replacement Considerations

The SI86S620EE-IS4 is a documented non-inverting variant within the same series. Substitution requires verification of logic polarity differences due to the inverting nature of the AS4 model. Ensure the replacement maintains the required 6.0 kVrms isolation and automotive qualification standards.
