Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'C' indicates the 2.5kVrms isolation rating, distinct from other variants like 'D' which may offer higher ratings. Confirm the package type matches the design footprint requirements. Check for AEC-Q100 automotive qualification status if deploying in vehicle applications. Ensure compatibility with the system's logic voltage levels and isolation barrier requirements before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated gate driver with 2.5kVrms isolation is required. It is suitable for driving MOSFETs or IGBTs in half-bridge configurations. Consider the 4A peak current capability for moderate power applications. Evaluate the 60ns propagation delay against switching frequency requirements. Compare against other Si823x variants if higher isolation voltage or different packaging is needed.
