UCC21330BDR is a dual-channel 3 kVRMS isolated gate driver with strong 4 A source and 6 A sink outputs, suited to high-side, low-side, and half-bridge power switching.

Best for

  • Isolated half-bridge gate drive
  • SiC MOSFET and IGBT switching stages
  • High-voltage DC/DC converters

Avoid if

  • The output supply cannot remain above the 8 V UVLO operating requirement
  • A non-isolated gate driver is sufficient
  • The design requires a documented product-page or EDA-model URL not provided in the source data

Check before use

  • Verify VDDA-VSSA and VDDB-VSSB voltage ranges and UVLO margin
  • Set RDT for measured system dead-time requirements
  • Keep local VDD-VSS bypass capacitors and gate-drive loops short
