SI8233AD-D-IS

Isolators - Gate Drivers Overview

The SI8233AD-D-IS is a dual-channel, galvanically isolated gate driver from the Si823x series by Skyworks Solutions. It utilizes capacitive coupling technology to provide high-speed signal transmission across isolation barriers. The device features a 5 kVRMS input-to-output isolation rating and supports up to 1500 VDC peak driver-to-driver isolation. It operates within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package. Key electrical parameters include a maximum propagation delay of 45 ns, rise/fall times of 12 ns, and a working supply current of 3.5 mA.

Isolators - Gate Drivers Feature Summary

• Provides complete galvanic isolation between input logic and output power stages using robust capacitive coupling technology.
• Features high electromagnetic immunity with a minimum common-mode transient rejection capability of 20 kV/µs for reliable operation in noisy environments.
• Integrates two independent drivers in a single package, supporting both high-side and low-side configurations for bridge applications.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters requiring robust isolation
• Automotive power electronics and battery management systems
• High-voltage switching power supplies and DC-DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D' indicates the correct isolation voltage rating and UVLO threshold for your design requirements. Confirm the package type matches your PCB footprint, as variations exist within the family. Check for AEC-Q100 qualification if automotive compliance is mandatory. Ensure compatibility with your control logic voltage levels before integration.

Isolators - Gate Drivers Selection Notes

Select this component when high isolation voltage and fast switching speeds are critical. The 5 kVRMS rating suits applications demanding significant safety separation. Consider the 16-SOIC package for board space constraints. Compare against lower-isolation variants if system requirements allow, or higher-current versions if driving larger MOSFETs/IGBTs is necessary.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, designed for industrial and automotive markets. It complements other Skyworks isolation products by offering integrated solutions for power stage control. The family emphasizes reliability through silicon dioxide isolation layers, replacing traditional magnetic transformers in many modern designs.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other Skyworks Si823x variants with similar pinouts but different isolation ratings or UVLO thresholds. Cross-reference with competitor parts offering comparable 5 kVRMS isolation and dual-channel functionality, ensuring package and electrical parameter alignment.
