  • LM5101A vs LM5102/LM5105 bootstrap diode losses

    Kevin Heppell
    Kevin Heppell
    Other Parts Discussed in Thread: LM5105 , LM5102 In comparing the datasheets for the LM5100/LM5101x with the datasheets for the LM5102 and LM5105, there is roughly a factor of 3.5x increase in boot-strap diode dissipation for the 02 and 05 parts for similar…

  • RE: LM5100A: LM5100A using issues

    Richard Herring

    Hello Thomas, For compatibility with 3.3V CMOS, I assume for the driver inputs, the LM5100A will not be compatible. The LM5100A has high turn on thresholds of 5.4V typical. Within this driver family the LM5101A is compatible since the threshold is 2.3V…

    Other Parts Discussed in Thread: LM5101A Hi, I've been working with the LM5101A for a week now and have been having some trouble getting a signal out of the HO output of the IC. Right now these drivers will be sending a signal to a half H-bridge that…

    Hi, Hui, The LM5101 isn't recommended for new designs. There is an LM5101A which is recommended, and has a model. You can use the model in the LM5101A web page for either device, though. Another alternative is one of our newer devices, UCC27282 which…

    Hello Viabhav, If you are running simulations, you can find the simulation models in the LM5101A product folder which should have the TTL compatible inputs. Please confirm if this addresses your question, or you can post additional questions on this thread…

    Hello Cheney, As you have likely seen from the datasheets the LM5101A and UCC27201 are similar half bridge drivers with 100V HS voltage rating and 3A drive current. The differences are mainly in two areas. The VDD rating of the UCC27201 recommended is…
