    Hi Karthik,

    You can expect the VEE2 of the driver to be able to handle much more than 300V.

    The maximum that it can handle is in the kV range.

    Hope this addresses your concern!

    Regards,

    Hiroki

    Hi Karthik,

    UCC5350-Q1 is an isolated gate driver. The gate driver an withstand 990VDC in D package and 2121VDC in DWV package from primary side ground to secondary side ground (GND1 to VEE2). The isolation specs are located in table 6.6 Insulation Specifications for D Package and table 6.7 Insulation Specifications for DWV Package.

    Either package would be able to withstand 300V on VEE2 with respect to primary side ground GND1.

    Best regards,

    Andy Robles

    Hi Karthik, 

    All of our available PSpice models are on the TI.com product page. In this case we only have the UCC5350-Q1 transient PSpice model available. 

    Thanks,
