SI8652BB-AS1

Digital Isolators Overview

The SI8652BB-AS1 is a five-channel digital isolator from the Si865x series, manufactured by Skyworks Solutions. It features three forward and two reverse channels with unidirectional signal transmission. The device operates on a supply voltage range of 2.375 V to 5.5 V and supports data rates up to 150 Mb/s. It provides an insulation voltage of 2.5 kVrms using capacitive coupling technology. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a pulse width distortion of 4.5 ns. It is qualified under AEC-Q100 standards for automotive applications and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates five independent digital isolation channels with a configuration of three forward and two reverse paths.
• Utilizes capacitive coupling technology to provide galvanic isolation between circuit domains.
• Includes an integrated shutdown pin for power management control.
• Meets automotive reliability requirements through AEC-Q100 qualification.

Digital Isolators Applications

• Automotive electronic control units requiring high-reliability signal isolation
• Industrial automation systems needing robust noise immunity
• Power electronics interfaces for motor drives and inverters

Digital Isolators Procurement Notes

Verify the specific suffix AS1 indicates automotive grade qualification and tube packaging. Confirm the QSOP-16 package variant matches your PCB footprint requirements. Ensure the design accounts for the specified humidity sensitivity level during storage and reflow soldering processes. Cross-reference the datasheet for exact thermal dissipation limits relative to ambient operating conditions.

Digital Isolators Selection Notes

Select this component when five isolated channels are required in a single package. The 2.5 kVrms rating suits applications with moderate isolation voltage needs. Consider the 150 Mb/s data rate capability for high-speed communication links. The unidirectional nature defines the signal flow directionality constraints. Verify compatibility with the 2.375 V to 5.5 V supply voltage range of the target system.

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 integrated DC/DC converter options in other variants. The SI8652BB-AS1 specifically targets automotive markets, distinguishing itself through AEC-Q100 certification. It shares core technological foundations with other members like the SI8652BD-B-IS but differs in insulation ratings and packaging.

Digital Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching channel count, insulation voltage, and package dimensions. Verify that any replacement maintains the same unidirectional signal path configuration and AEC-Q100 automotive qualification status if required.
