Can mosfet driver supply continuous current of 2Amps?

[Aankur]

Hello

I am using a MOSFET driver circuit to supply power from one section to another section in my design.
I need to pass 2Amps current from one section to another section in my design.
I have selected SI2301 (p-channel mosfet) and SI2302 (n-channel mosfet).
My application is a continuous running application.

For how long can the MOSFET driver circuit supply a continuous current of 2 Amps?

Thanks

You cannot increase the current and keep the voltage the same continuously without another source.

Short answer no. This P-channel mosfet is only rated at -2.3A  at its best probably more like -1.5A on a pcb in a warm enclosure. Its life will be short and smokey. How about a SI2371?
You want the lowest Rdson*Id you can afford (Id more like 5A) for relaibility. In fact a 5A device may well be cheaper. The NMOS only has to sink a few mA making R3 superfluous. You can get away with the most lowly npn With R65 increased to 10k.
