SI8233AB-D-IM1

Isolators - Gate Drivers Overview

The SI8233AB-D-IM1 is a dual-channel isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide galvanic isolation with a rated insulation voltage of 2.5 kVrms. The device features high-side and low-side outputs capable of delivering up to 4 A peak output current. It operates within a supply voltage range of 9.4 V to 24 V for the output stage and accepts TTL-compatible logic inputs between 4.5 V and 5.5 V. Key electrical characteristics include a maximum propagation delay of 45 ns, rise and fall times of 12 ns, and a power dissipation rating of 1.2 W. The component is qualified under AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to +125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D' indicates the required isolation voltage level (2.5 kVrms) versus other variants like 'B' or 'C'. Confirm the 'IM1' package designation matches the QFN-14 footprint requirements for your PCB layout. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number against Skyworks official databases to avoid counterfeit components, as this part may have specific lifecycle statuses such as active or obsolete depending on the region.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2.5 kVrms isolation is required for space-constrained designs using the QFN-14 package. It is suitable for applications demanding fast switching speeds with 45 ns propagation delay. Consider alternative packages like SOIC if leaded connections are preferred over surface mount QFN. Verify that the system's common-mode transient immunity requirements align with the datasheet specifications before finalizing the design.

Isolators - Gate Drivers Part Context

The SI8233AB-D-IM1 belongs to the Si823x family of isolated gate drivers from Skyworks Solutions. This series leverages silicon isolation technology to replace traditional magnetic transformers. The AB variant specifically denotes the 2.5 kVrms isolation rating. The IM1 suffix identifies the 14-lead QFN package format. This family is designed to offer flexibility in grounding configurations and supports both positive and negative voltage supplies for the output stage.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks documentation for direct pin-to-pin replacements within the Si823x family, such as SI8233BB-D-IM or SI8233BD-D-ISR, noting differences in isolation voltage ratings and package types. Verify that any substitute maintains the 2.5 kVrms isolation requirement and 4 A peak current capability. Ensure the replacement part supports the same QFN-14 footprint or requires PCB re-layout.
