SI8652AB-AS1

Digital Isolators Overview

The SI8652AB-AS1 is a five-channel automotive digital isolator from Skyworks Solutions, featuring three forward and two reverse unidirectional channels. It utilizes capacitive coupling technology to provide an insulation voltage of 2500 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and consumes 5.6 mA of operating current. The component is housed in a 16-pin SOIC-Narrow package and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Digital Isolators Procurement Notes

Verify the specific suffix 'AS1' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel configuration. Ensure that the AEC-Q100 qualification status aligns with your project's reliability requirements. Cross-reference the 2500 Vrms insulation rating with system safety standards before finalizing procurement.

Digital Isolators Selection Notes

Select this component when high-speed isolation is required for automotive environments. The 150 Mb/s data rate suits fast communication protocols. Consider the 16-pin SOIC-Narrow footprint for PCB layout constraints. Verify that the 2500 Vrms isolation level meets the specific circuit voltage requirements compared to higher-rated variants.

Digital Isolators Part Context

This part belongs to the Si865x series of digital isolators. It shares the same core architecture as other members like the SI8652BC but differs in insulation voltage ratings and packaging options. The series is designed for robust performance in noisy electrical environments typical of modern vehicle architectures.

Digital Isolators Replacement Considerations

The SI8652BB-B-IS1R offers similar channel counts and speed but features a QSOP-16 package. The SI8652BC-B-IS1 provides higher insulation voltage (3750 Vrms) in a SOIC-Narrow-16 package. Verify pinout compatibility and thermal characteristics before substitution.
