UCC21551CQDWKRQ1 is an automotive-qualified, reinforced-isolation dual gate driver intended for high-side, low-side, and half-bridge MOSFET, SiC MOSFET, or IGBT drive.

Best for

  • Automotive high-voltage DC-DC converters
  • On-board battery chargers
  • Half-bridge SiC MOSFET or IGBT gate drive

Avoid if

  • A gate-bias supply below the C-version UVLO operating range is required
  • Independent output overlap is needed while programmed interlock dead time is enabled

Check before use

  • Confirm VDDA/VSSA and VDDB/VSSB supply margins against UVLO thresholds
  • Measure gate ringing and output transients at the driver pins
  • Check PCB isolation, creepage, clearance, and thermal design
