Multisim Convergence Error MOSFET Gate Driver

[timbitss]

Hi,

I don't understand why I am receiving a convergence error when attempting to simulate my H-bridge circuit after introducing the TC4420 MOSFET gate driver.

Specifically, I am receiving this error when I supply the gate driver with a voltage of greater than 13 V, even though the datasheet attached below mentions a maximum Vdd = 18V. Does anyone know why this is the case? 

Thanks

I have had similar problems..I changed the RSHUNT value in Custom analysis options and got the driver to work.

Thanks! I also had to reduce the error tolerances but that was the missing link.
