SI8237AC-AS1

Isolators - Gate Drivers Overview

The SI8237AC-AS1 is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions. It features a 2500 Vrms isolation rating and operates with an 8 V under-voltage lockout (UVLO). The device provides high peak output currents of 500 mA for both high-side and low-side channels. It utilizes capacitive coupling technology for signal transmission across the isolation barrier. The component is housed in a 16-pin SOIC package and supports TTL logic inputs.

Isolators - Gate Drivers Feature Summary

• Dual-channel configuration supporting independent high-side and low-side drive applications
• Capacitive coupling technology ensures robust galvanic isolation between input and output domains
• High electromagnetic immunity designed for reliable operation in electrically noisy environments

Isolators - Gate Drivers Applications

• Solid-state transformer architectures needing high-frequency switching isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS1 against official Skyworks documentation to confirm pinout and electrical characteristics. Ensure compatibility with system voltage levels and isolation requirements before integration. Cross-reference datasheet revisions to avoid discrepancies in timing parameters or packaging details during procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2500 Vrms isolation is required. Consider the 500 mA peak current capability for driving medium-power MOSFETs or IGBTs. Evaluate the 8 V UVLO threshold against the available supply rails to ensure proper turn-on behavior under varying load conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers. The family shares common architectural features such as capacitive isolation and high-speed propagation. Variants within the series differ primarily in isolation ratings, UVLO thresholds, and package options, allowing designers to tailor solutions for specific voltage and form-factor constraints.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks documentation for direct replacements within the Si823x series. Verify that alternative parts match the 2500 Vrms isolation and 500 mA output current specifications. Confirm pin-to-pin compatibility if substituting in existing layouts.
