SI8652BC-AS1

Digital Isolators Overview

The SI8652BC-AS1 is an automotive-grade digital isolator from the Si865x series, manufactured by Skyworks Solutions. It features a 16-pin SOIC package with five channels configured as three forward and two reverse. The device utilizes capacitive coupling for isolation, supporting data rates up to 150 Mb/s with a propagation delay of 8 ns. It operates on a supply voltage between 2.5 V and 5.5 V, consuming 5.6 mA. Key electrical parameters include an insulation voltage of 3750 Vrms, rise/fall times of 4 ns, and pulse width distortion of 0.2 ns. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Applications

• Automotive battery management systems
• Inverter control circuits
• Motor drive interfaces

Digital Isolators Procurement Notes

Verify that the specific part number includes the 'BC' suffix to confirm automotive grade compliance and AEC-Q100 certification. Ensure the 'AS1' suffix matches the required tape-and-reel or tube packaging format specified in the official datasheet. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and moisture sensitivity levels prior to procurement.

Digital Isolators Selection Notes

Select this component when asymmetric signal flow is required, specifically needing three unidirectional channels in one direction and two in the opposite. It is suitable for designs requiring 3750 Vrms isolation with low power consumption. Consider the 16-pin SOIC footprint for PCB layout constraints. This model is appropriate for applications where standard symmetric isolators do not fit the directional logic requirements of the system architecture.

Digital Isolators Part Context

This device belongs to the Si865x family of ultra-low power digital isolators. It shares core architectural similarities with other members like the SI8650BC-AS1 but differs in channel polarity distribution. While the SI8650 offers five forward channels, the SI8652 provides a hybrid configuration. Both utilize Skyworks' capacitive isolation technology and are designed for robust performance in electric vehicle and industrial power conversion applications.

Digital Isolators Replacement Considerations

The SI8652BC-B-IS1 is a verified substitute offering identical electrical specifications and channel configuration. It maintains the same 3.75 kVrms isolation rating and 150 Mb/s data rate. Verify that the alternative package variant meets the thermal and mechanical requirements of the existing design before substitution.
