SI8652BB-AS1R

Digital Isolators Overview

The SI8652BB-AS1R is a Skyworks Solutions digital isolator featuring five channels with three forward and two reverse directions. It operates within a supply voltage range of 2.375 V to 5.5 V and supports data rates up to 150 Mb/s. The device provides an insulation voltage of 2500 Vrms and utilizes capacitive coupling technology. Key timing parameters include an 8 ns propagation delay, 4 ns rise/fall times, and a pulse width distortion of 4.5 ns. It is qualified under AEC-Q100 standards for automotive applications and functions reliably between -40°C and +125°C.

Digital Isolators Feature Summary

• Integrates five independent signal paths with configurable unidirectional polarity
• Employs capacitive coupling for high-speed digital isolation
• Includes a shutdown control pin for power management
• Meets automotive reliability requirements through AEC-Q100 qualification

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication
• Industrial motor drives with galvanic isolation needs
• Power inverter systems utilizing high-voltage separation
• General-purpose digital isolation in noisy environments

Digital Isolators Procurement Notes

Verify the specific suffix AS1R indicates reel packaging when sourcing components. Confirm that the BB variant corresponds to the standard 2500 Vrms insulation rating rather than higher voltage options. Ensure compatibility with SOIC-16 footprint dimensions during PCB layout. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Digital Isolators Selection Notes

Choose this component when five isolated channels are required in a single package. The unidirectional configuration suits applications where signal flow is strictly one-way across the isolation barrier. Consider the 150 Mbps speed limit against system bandwidth requirements. The automotive qualification makes it suitable for harsh operating environments compared to commercial grade alternatives.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators from Skyworks Solutions. The family combines high-speed signal isolation with robust performance characteristics. These devices are designed to replace traditional optocouplers in modern electronic designs. The series offers various channel counts and insulation ratings to suit different application constraints.

Digital Isolators Replacement Considerations

SI8652BB-B-IU shares identical electrical specifications but uses QSOP-16 packaging instead of SOIC-16. Verify pinout compatibility before substitution due to potential mechanical differences. Other Si865x variants may offer different channel configurations or insulation voltages.
