UCC21551CDWKR is a 14-pin dual-channel reinforced-isolation gate driver with 4 A source and 6 A sink capability. The C suffix selects the 12 V nominal VDD UVLO option; use an output bias supply from 13.5 V to 25 V.

Best for

  • Isolated half-bridge gate drive
  • SiC MOSFET, MOSFET, and IGBT drive
  • Power conversion and inverter control

Avoid if

  • A lower output-bias UVLO threshold is required
  • The required gate-drive voltage is below 13.5 V
  • A package other than 14-pin DWK SOIC is required

Check before use

  • Verify VDD UVLO behavior for the C option.
  • Set and validate dead time using the DT resistor.
  • Place local low-ESR and low-ESL bypass capacitors close to VDD/VSS pins.
  • Validate creepage, clearance, and switch-node layout at system voltage.
