Gate Drivers

120 V bootstrap driver4 A gate driverTTL inputHalf bridgePowerPAD SOIC-8

UCC27211DDAR is a fast 120 V bootstrap half-bridge MOSFET driver with independent TTL-compatible high-side and low-side inputs in a thermally enhanced SOIC-8 package.

Best for

  • Half-bridge N-channel MOSFET stages
  • Synchronous buck power stages
  • High-frequency isolated power converters

Avoid if

  • The controller cannot guarantee non-overlap between high-side and low-side commands
  • The high-side switch must remain on indefinitely without a bootstrap refresh interval
  • Gate-drive voltage below the 8 V recommended operating minimum is required

Check before use

  • HI and LI timing and external dead-time implementation
  • High-side MOSFET gate charge and bootstrap capacitor voltage droop
  • HS transient voltage and PCB loop inductance
  • Current availability from the intended supplier
