SI8650BB-AUR

Digital Isolators Overview

The SI8650BB-AUR is a Skyworks Solutions digital isolator featuring five forward channels with unidirectional signal transmission. It utilizes capacitive coupling technology to provide an isolation voltage of 2500 Vrms. The device supports data rates up to 150 Mb/s and operates within a supply voltage range of 2.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8 ns, rise and fall times of 4 ns, and a pulse width distortion of 0.2 ns. It functions at temperatures from -40°C to +125°C and consumes 7 mA of operating current. The component is housed in a QSOP-16 package.

Digital Isolators Feature Summary

• Provides galvanic isolation for five independent signal channels using capacitive coupling technology.
• Supports high-speed data transmission with a maximum rate of 150 Mb/s.
• Designed for automotive applications with extended temperature range capabilities.
• Features low power consumption suitable for energy-efficient system designs.

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable signal isolation
• Power electronics circuits requiring high-voltage barrier protection

Digital Isolators Procurement Notes

Verify the specific suffix 'AUR' corresponds to the reel packaging format when sourcing components. Confirm that the automotive grade designation aligns with project requirements. Ensure compatibility with the QSOP-16 footprint during PCB layout. Check for moisture sensitivity level compliance if storage conditions are critical. Validate that the 2500 Vrms isolation rating meets the safety standards of the target application environment.

Digital Isolators Selection Notes

Select this part for designs requiring five isolated channels with unidirectional data flow. Consider the 2500 Vrms isolation barrier for standard industrial or automotive voltage levels. Evaluate the 150 Mb/s speed against system timing requirements. Compare the 7 mA current draw against power budget constraints. Ensure the QSOP-16 package fits the available board space and manufacturing capabilities.

Digital Isolators Part Context

This component belongs to the Si865x family of digital isolators from Skyworks Solutions. The series offers various channel counts and isolation voltages. The SI8650 variant specifically provides five channels. The BB suffix indicates automotive qualification. The AUR suffix denotes tape and reel packaging for automated assembly processes.

Digital Isolators Replacement Considerations

SI8650BB-AU serves as a tube-packaged alternative within the same functional specification. SI8650EB-AUR is a similar automotive-grade option but may differ in specific qualification details. Verify pinout and parameter equivalence before substitution.
