Hi Ramesh,
Please note section 8.1.2 of the datasheet:
8.1.2 Optional Series Gate Resistor
In high current or high voltage applications, the low side predriver fault may assert due to noise in the system. In
this application, TI recommends placing a 47 to 120-Ω resistor in series with the low side output and the gate of
the low side FET. TI also recommends setting the dead time to 850 ns when adding a series resistor.
We hope this will solve your problem.
