I found the PCB layout but seemed to have lost the schematic. Since SG3525 has complementary outputs with dead time. You need to couple (OR) both the outputs and drive the MOS.

The current sense input works on a pulse by pulse limiting followed by a soft start for persistent overload.
Thank you Sougata.
I'm sorry to strees you. Could I ask even a Paint-made schematic of what do you mean?
Maybe you mean take the signal from output A and B and connect to the input of an OR gate?
Then from the output of the OR gate, drive a logic mosfet. Correct?

I've found this info:

Is that a good application, in your opinion?
