SI8234BB-D-IS1

Isolators - Gate Drivers Overview

The SI8234BB-D-IS1 is a dual-channel, current-isolated gate driver manufactured by Skyworks Solutions Inc. It features two completely isolated drivers within a single package, providing up to 5 kVRMS input-to-output isolation and 1500 VDC peak driver-to-driver isolation. The device operates with an 8V UVLO threshold and supports high-side and low-side configurations. It delivers a peak output current of 4 A and functions within a temperature range of -40°C to +125°C. The component is housed in a 16-SOIC narrow package (SOIC-Narrow-16) and is qualified under the AEC-Q100 standard for automotive applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1' corresponds to the SOIC-Narrow-16 package variant, as other suffixes like 'IS' indicate wide packages. Confirm AEC-Q100 automotive qualification status if required for your application. Check datasheet for humidity sensitivity level and reflow soldering profile constraints. Ensure voltage ratings match system requirements.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with 5 kVRMS rating is necessary. Consider the 4 A peak drive current capability for driving MOSFETs or IGBTs. Evaluate the 16-pin narrow SOIC footprint against board space constraints. Verify compatibility with TTL logic inputs and 8V UVLO thresholds before integration into the design.
