SI8271ABD-AS

Isolators - Gate Drivers Overview

The SI8271ABD-AS is a single-channel, galvanically isolated gate driver from the Si8271 series by Skyworks Solutions. It features a SOIC-8 surface-mount package and operates within a temperature range of -40°C to +125°C. The device supports an input voltage range of 2.5 V to 5.5 V with TTL logic compatibility. Key electrical parameters include a maximum propagation delay of 75 ns, rise time of 16 ns, and fall time of 18 ns. It provides 2.5 kVrms isolation voltage and draws 10 mA of operating supply current while delivering 4 mA output current at a 5 V output voltage level.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity for reliable operation in noisy environments
• Integrated under-voltage lockout (UVLO) for stable driver performance
• Low latency and skew characteristics for precise timing control

Isolators - Gate Drivers Applications

• Industrial motor drives
• Power supply gate driving

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm packaging type and regional availability constraints. Ensure the selected variant matches the required isolation voltage and UVLO specifications for the target application environment before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with low propagation delay is required alongside robust galvanic isolation. The single-channel configuration suits applications needing independent control of one switch. Consider the SOIC-8 footprint for PCB layout compatibility and verify thermal dissipation requirements given the 1.1 W power dissipation rating.

Isolators - Gate Drivers Part Context

This part belongs to the Si8271 family of ISOdrivers, designed for high-performance isolated gate driving. The series emphasizes high CMTI and low latency, making it suitable for modern power conversion topologies. The ABD-AS designation indicates a specific automotive-grade or industrial-grade variant within the broader product line.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks datasheets for direct pin-compatible alternatives within the Si8271 family that may offer different insulation ratings or packaging options. Verify functional equivalence regarding propagation delay and output current capabilities before substituting.
