SI8230AB-AS

Isolators - Gate Drivers Overview

The SI8230AB-AS is a dual-channel, galvanically isolated gate driver from the Si823x series by Skyworks Solutions. It features high electromagnetic immunity and operates within an extended temperature range of -40°C to +125°C. The device provides 2.5 kVrms isolation voltage and supports both high-side and low-side configurations. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 20 ns each, and a quiescent supply current of 3.5 mA. It delivers a peak output current of 500 mA with an 8 V output voltage level. The component is housed in a narrow SOIC-16 package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS against official Skyworks documentation to confirm package type and tape/reel specifications. Ensure compatibility with system isolation requirements and thermal management needs. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any recent design changes or obsolescence notices from the manufacturer before finalizing procurement plans.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with moderate speed (45 ns delay) is required. It is suitable for applications needing 2.5 kVrms isolation rather than higher voltage ratings found in other series members. Consider the narrow SOIC-16 footprint for space-constrained designs. Verify that the 500 mA output current meets the gate charge requirements of the target power devices.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which utilizes Skyworks' proprietary capacitive coupling technology. Unlike magnetic or optical isolators, these devices offer superior reliability and smaller form factors. The SI8230AB-AS specifically targets automotive and industrial markets requiring robust isolation and high noise immunity.

Isolators - Gate Drivers Replacement Considerations

Direct replacements may include other parts within the Si823x family such as SI8230AC-AS or SI8230BD-IS3, depending on required isolation voltage and packaging preferences. Verify pinout compatibility and electrical specifications before substitution.
