SI88241BD-ASR

Digital Isolators Overview

The SI88241BD-ASR is a Skyworks Solutions automotive-grade digital isolator featuring four independent channels. It provides 5000 Vrms isolation voltage and supports data rates up to 100 Mbps with a propagation delay of 18 ns. The device offers common-mode transient immunity of 40 kV/µs and operates within a supply voltage range of 3 V to 5.5 V. Packaged in a 20-SOIC (0.295 inch width) format, it is designed for high-reliability applications requiring robust signal integrity across isolated boundaries.

Digital Isolators Feature Summary

• Automotive-grade qualification for reliable operation in demanding environments
• High common-mode transient immunity ensuring signal stability during rapid voltage changes
• Integrated DC-DC converter capability for isolated power generation

Digital Isolators Applications

• Automotive battery management systems
• Electric vehicle charging infrastructure
• Inverter control circuits

Digital Isolators Procurement Notes

Verify the specific suffix ASR against official Skyworks documentation to confirm automotive grade status and reel packaging specifications. Ensure compatibility with 20-SOIC footprint requirements. Cross-reference RoHS compliance details directly from the manufacturer datasheet prior to integration into production schedules.

Digital Isolators Selection Notes

Select this component when automotive reliability standards are mandatory alongside high-speed digital isolation. The 4-channel configuration suits complex bus architectures. Verify that the 100 Mbps speed meets system timing constraints. Confirm that the 5000 Vrms isolation rating exceeds the circuit's peak voltage requirements for safety margins.

Digital Isolators Part Context

This part belongs to the Si88241 series of digital isolators from Skyworks Solutions. It shares architectural similarities with other members like the SI88240 and SI88243 but is distinguished by its specific automotive qualification and package variant. The series focuses on providing robust isolation solutions for industrial and transportation sectors.

Digital Isolators Replacement Considerations

The SI88240BD-IS and SI88243BD-IS are related family members but carry 'Not Recommended for New Designs' status. Direct substitution requires careful evaluation of pinout compatibility and functional differences between channel configurations and integrated converter options.
