It provides 2500 Vrms isolation voltage and supports a common-mode transient immunity of 150 kV/µs. The device operates on a supply voltage range of 2.25 V to 5.5 V, with typical rise and fall times of 2.5 ns and maximum propagation delays of 42 ns. It is housed in a 16-SSOP package and meets AEC-Q100 automotive qualification standards for operation between -40°C and +125°C.

Digital Isolators Feature Summary

• Capacitive coupling technology ensures galvanic isolation without magnetic interference
• High common-mode transient immunity supports reliable signal transmission in noisy environments
• Automotive-grade qualification ensures durability under extreme temperature conditions

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication
• Industrial motor drive systems needing high-speed signal isolation
• Power conversion circuits utilizing isolated gate driver interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'AUR' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm AEC-Q100 compliance status through official Skyworks documentation prior to integration. Ensure input voltage levels match the specified 2.25 V to 5.5 V operational range for proper functionality.

Digital Isolators Selection Notes

Select this component when high-speed bidirectional or unidirectional isolation is required in automotive applications. Compare against standard industrial grades if extended temperature ranges or higher isolation voltages are necessary. Evaluate channel count requirements as this model strictly provides four unidirectional paths within a single package.

Digital Isolators Part Context

The SI86SQ44 series belongs to Skyworks' automotive-grade digital isolator family designed for robust performance in electric vehicles. These devices utilize proprietary capacitive isolation technology to replace traditional optocouplers, offering superior speed and reliability. The EB variant specifically targets evaluation and development phases within automotive design cycles.

Digital Isolators Replacement Considerations

SI86SQ44BB-AU serves as a parameter-equivalent alternative within the same product line. Verify package compatibility and supply chain availability before substitution. Cross-reference datasheet specifications to ensure identical electrical characteristics for seamless integration.
