SI86S660BB-AUR

Digital Isolators Overview

The SI86S660BB-AUR is a six-channel unidirectional SPI digital isolator from Skyworks Solutions, designed for automotive applications. It features capacitive coupling technology with a 2500Vrms isolation voltage and supports data rates up to 150Mbps. The device operates within a supply voltage range of 2.25V to 5.5V and withstands a minimum common-mode transient immunity of 150kV/µs. It is housed in a 16-SSOP package (0.154" width) and complies with AEC-Q100 standards for operation across a temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

• Six-channel unidirectional signal isolation using capacitive coupling technology
• Automotive-grade reliability certified under AEC-Q100 standards
• High-speed data transmission capability supporting up to 150Mbps
• Robust noise immunity with a minimum common-mode transient rejection of 150kV/µs

Digital Isolators Applications

• Automotive electronic control unit (ECU) communication interfaces
• Inverter gate drive circuits in electric vehicles
• Battery management system (BMS) isolated communication links
• On-board charger (OBC) signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'AUR' indicates tape-and-reel packaging when sourcing components. Confirm that the automotive grade designation aligns with project requirements for AEC-Q100 compliance. Ensure the 16-SSOP footprint matches the target PCB layout dimensions. Cross-reference the datasheet revision date to confirm current electrical specifications before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component for designs requiring high channel density in a compact surface-mount package. The 150kV/µs CMTI rating makes it suitable for noisy environments typical in power electronics. Consider the 2.25V to 5.5V operating range for compatibility with various logic levels. The unidirectional configuration is ideal for one-way data transfer applications where feedback channels are not required.

Digital Isolators Part Context

This part belongs to the Si86S6x series of automotive digital isolators. It complements other variants like the SI86S660BB-AU which offers tube packaging instead of reel. The series provides scalable isolation solutions for complex automotive networks, balancing performance with size constraints in modern vehicle architectures.

Digital Isolators Replacement Considerations

SI86S660BB-AU serves as a parameter-equivalent alternative differing primarily in packaging format rather than electrical function.
