SI88640BD-ASR

Isolators - Gate Drivers Overview

The SI88640BD-ASR is a unidirectional digital isolator from the Si88640 series, manufactured by Skyworks Solutions. It features four independent channels housed in a SOIC-24 surface-mount package. The device supports data rates up to 100 Mb/s with a propagation delay of 18 ns and rise/fall times of 25 ns. It operates on a supply voltage between 3 V and 5.5 V, drawing 13.3 mA of operating current. The isolator provides 5000 Vrms insulation voltage and functions within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Unidirectional signal transmission across four isolated channels
• High insulation voltage capability for safety-critical isolation
• Operation without a dedicated shutdown control pin
• Compliant with RoHS environmental standards

Isolators - Gate Drivers Applications

• Industrial automation systems requiring galvanic isolation
• Power electronics gate drive circuits
• Medical equipment signal isolation
• Data acquisition systems with high noise environments

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix ASR indicates tape-and-reel packaging when ordering. Confirm that the SOIC-24 footprint matches your PCB design constraints. Ensure the unidirectional channel configuration aligns with your circuit topology requirements before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring four-channel unidirectional isolation with moderate speed requirements. Consider the SOIC-24 package size relative to available board space. Verify that the 100 Mb/s data rate meets your system's communication needs and that the 5000 Vrms isolation rating satisfies safety standards.

Isolators - Gate Drivers Part Context

This part belongs to the Si88640 family of digital isolators designed for robust performance in noisy environments. It serves as an interface solution between low-voltage logic and higher-voltage power stages. The device replaces traditional optocouplers in many modern designs due to its smaller size and consistent performance characteristics.
