MAX5064AATC+ BBM

[rpdavis]

Hello, I’m new to Multisim and am having trouble with the MAX5064AATC+ model in Multisim 14.  I selected it because it has break before make but when I run the simulation I get a big surge of current when the FET’s turn on and off.  I have adjusted the BBM resistor and it does affect the timing  but I cannot stop the FET’s from both being on at the same time.

Any help would be greatly appreciated.

Here is more information, the model has a problem when I tie INH+ low and INH- hi and the DH output still pules with INL input pules.  But when I reverse it and apply the pulse input to INH and tie INL for a fixed hi output the DL does not pulse.  But if I tie INL for a low output the DH gives a sign wave amplitude 40V to about 43V.  The conclusion I come to is that the model is incorrect and I don’t know enough knowledge to fix it.

Hi;

Can you attach the schematic to try to reproduce the issue?

hello PedroMunoz 

Thanks for the reply.

Please check the attachment of the first message.  I tried to attach the actual MAX5064.ms14 but ".ma14" is not an acceptable attachment.
