SI8234AB-D-IM

Isolators - Gate Drivers Overview

The SI8234AB-D-IM is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It features a 14-LGA (5x5 mm) surface-mount package and supports high-side and low-side configurations. The device provides 2.5 kVrms isolation voltage and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 12 ns, and a peak output current of 4 A. It requires an input voltage between 4.5 V and 5.5 V and consumes 3.5 mA of quiescent supply current.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D-IM' corresponds to the 14-LGA package and 2.5 kVrms rating during sourcing. Confirm AEC-Q100 automotive qualification status if required for your application. Check datasheet revisions for any pinout or parameter updates before finalizing design integration.

Isolators - Gate Drivers Selection Notes

Select this component when a compact 14-pin LGA footprint is preferred over SOIC packages. Ensure the system requires 2.5 kVrms isolation rather than higher ratings found in other series variants. Verify that the TTL-compatible input logic aligns with the controller interface.
