SI8655BA-ASR

Digital Isolators Overview

The SI8655BA-ASR is a unidirectional automotive digital isolator from the Si865x series, manufactured by Skyworks Solutions. It features five forward channels with no reverse channels, housed in a 16-SOIC package. The device supports data rates up to 150 Mb/s and offers an insulation voltage of 1000 Vrms using capacitive coupling technology. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a pulse width of 5 ns. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation for high-speed digital signals via capacitive coupling technology.
• Designed specifically for automotive applications meeting AEC-Q100 qualification standards.
• Supports high common-mode transient immunity to ensure signal integrity in noisy environments.

Digital Isolators Applications

• Automotive battery management systems
• Electric vehicle motor control interfaces
• Inverter gate drive circuits
• On-board charger communication links

Digital Isolators Procurement Notes

Verify that the specific suffix 'ASR' corresponds to the required tape-and-reel packaging configuration rather than tube packaging. Confirm that the SOIC-16 body width matches the target PCB footprint constraints. Ensure the component meets the specific AEC-Q100 grade requirements for the intended automotive application environment.

Digital Isolators Selection Notes

Select this component when a unidirectional five-channel isolator is required for automotive power electronics. It is suitable for designs needing 1 kV isolation with high-speed data transmission capabilities. Consider the thermal dissipation characteristics of the SOIC-16 package for high-density layouts.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, which utilizes Skyworks' proprietary silicon dioxide (SiO2) isolation technology. The family provides robust performance for industrial and automotive markets, offering superior reliability compared to traditional optical or magnetic isolators.

Digital Isolators Replacement Considerations

SI8655BA-AS: Identical functional specifications but supplied in tube packaging instead of reel. SI8655BA-B-IS1R: Similar 5-channel isolator with shutdown functionality and different minimum supply voltage specifications.
