  LM5105: PSpice simulation - dead time doesn't change

  TI Thinks Resolved

  Part Number: LM5105 Dear Team, Could you please help with my customer question below ? When I ran the PSpice model the dead time doesn’t change even if I change the RDT resistor. Is this correct behavior ? Best regards, Nir.

  LM5105: Lower gate drive voltage

  TI Thinks Resolved

  Part Number: LM5105 Is there a way to lower the LO and HO gate drive voltage on the LM5105 device? I am currently testing out a circuit that uses the LM5105 to drive the FETs of a H-bridge (see schematic). The H-bridge is driving an inductive load....

  LM5105: not working in continuous mode with the N channel fets at about 16VDC and above.

  TI Thinks Resolved

  Part Number: LM5105 We are trying to use the LM5105 to drive two N channel FETS that will control the 50V B+ to the drain of a RF power GAN transistor. We chose this IC, due to ability to quickly turn on and off our 50V B+ rail. We would like CW as well...
