SI88622BD-AS

Overview

The SI88622BD-AS is a Skyworks Solutions digital isolator featuring two unidirectional channels in a 20-pin SOIC package. It operates on a supply voltage range of 3 V to 5.5 V with a typical operating current of 7.5 mA. The device supports data rates up to 100 Mb/s and provides an insulation voltage of 5000 Vrms. Key timing parameters include a propagation delay of 18 ns, rise/fall times of 2.5 ns, and pulse width distortion of 4.5 ns. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal transmission between isolated domains.
• Features unidirectional channel configuration designed for specific input-output signal routing requirements.
• Includes high common-mode transient immunity capabilities to maintain signal integrity in noisy environments.

Applications

• Industrial communication interfaces requiring robust signal isolation
• General-purpose digital isolation in mixed-signal systems
• Automotive electronic control units needing certified isolation barriers

Procurement Notes

Verify the exact suffix 'AS' against official Skyworks documentation to confirm pinout and electrical specifications. Ensure compatibility with the 20-SOIC footprint during PCB layout. Confirm that the unidirectional channel count meets system design needs before ordering. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a 2-channel unidirectional isolator is required with a 20-pin form factor. Compare the 18 ns propagation delay against system timing budgets. Evaluate the 7.5 mA supply current against power constraints. Consider the 5000 Vrms isolation rating relative to the application's safety standards.

Part Context

This part belongs to the Si8862x series of general-purpose digital isolators from Skyworks Solutions. It utilizes proprietary iCoupler chip-scale transformer technology to provide isolation without external magnetics. The series is designed for applications demanding high reliability and low power consumption in compact packages.

Replacement Considerations

SI88622BC-ISR is listed as a substitute option. Verify functional equivalence regarding channel directionality and package dimensions before replacement.
