U3115D is a SOP-8 half-bridge gate driver for high-side and low-side N-channel MOSFET or IGBT control up to a 300 V switching node.

Best for

  • 300 V half-bridge MOSFET or IGBT stages
  • Applications needing bootstrap high-side drive
  • Designs using active-low low-side control logic

Avoid if

  • A high-side supply cannot be refreshed by bootstrap operation
  • The controller requires active-high LIN without logic inversion
  • The switching node exceeds the specified 300 V operating range

Check before use

  • Verify HIN and LIN polarity against the U3115D truth table.
  • Validate bootstrap capacitor operation across duty cycle, load, and temperature.
  • Check gate resistance, dead time, and switching-node transient margin.
