• Isolated DC-DC converter topologies demanding compact form factors

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1R' corresponds to the reel packaging variant rather than tube packaging when sourcing. Confirm that the 2.5 kVrms isolation rating aligns with your system's safety requirements. Ensure the narrow-body SOIC-16 footprint matches your PCB layout constraints. Check for any recent updates to the datasheet regarding operating conditions or recommended circuit parameters before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when automotive certification (AEC-Q100) is mandatory for the application. Choose this part if a narrow-body SOIC-16 package is required to save board space compared to standard SOIC variants. Consider this driver for designs requiring 2.5 kVrms isolation with capacitive coupling technology instead of magnetic transformers. Verify that the 3 V to 5.5 V logic supply range fits your microcontroller or controller interface levels.

Isolators - Gate Drivers Part Context

This device belongs to the Si823Hx family of isolated gate drivers from Skyworks Solutions. The family utilizes silicon dioxide (SiO2) based capacitive isolation technology. Other members in the series offer varying isolation voltages and channel counts, such as single-channel or higher voltage ratings, but share similar operational principles and package options like SOIC-8, SOIC-14, and SOIC-16.
