SI823H9AD-AS4

Isolators - Gate Drivers Overview

The SI823H9AD-AS4 is a galvanically isolated single-channel gate driver from Skyworks Solutions, designed for automotive applications. It features a 5.0 kV isolation rating and utilizes silicon dioxide (SiO2) technology for high reliability. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. Packaged in an 8-pin Wide Body SOIC (SOIC-8), it provides robust signal transmission across isolation barriers.

Isolators - Gate Drivers Feature Summary

• Utilizes silicon dioxide dielectric technology for reliable galvanic isolation
• Designed specifically for automotive grade environments with AEC-Q100 qualification
• Provides high electromagnetic immunity for stable operation in noisy power systems

Isolators - Gate Drivers Applications

• Automotive power management systems
• High-voltage motor control circuits
• Industrial inverter drives

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS4 corresponds to the tube packaging format when ordering. Confirm that the component meets AEC-Q100 requirements for your specific automotive application tier. Ensure compatibility with the 8-SOIC footprint during PCB layout. Cross-reference the manufacturer datasheet for moisture sensitivity handling instructions prior to assembly.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring a single-channel driver with high isolation voltage in an automotive context. Consider the 8-pin package constraint against available board space. Evaluate the 5.0 kV rating against system insulation requirements. Compare propagation delay specifications if high-speed switching is critical for the target load.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx series of isolated gate drivers. It complements dual-channel variants like the SI823H6AD-AS3 by offering a simplified single-driver solution. The series leverages Skyworks' proprietary SiO2 isolation technology, distinguishing it from traditional optocoupler or capacitive isolation alternatives in the market.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other single-channel automotive isolated gate drivers with similar 5kV ratings and SOIC-8 packages. Verify pinout compatibility before replacing. Check if alternative parts meet the same AEC-Q100 qualification standards required for the original design.
