The irl2203ns handles 82 ~ 110A @ 10v drive. Running a 12v supply I have used a PNP/NPN driver. Basically pnp emitter to 12v and collector to gate of FET. A base bias keeps the PNP in the off region and finally a npn pulls the pnp base bias low to turn on the FET. Works like a charm every time I have used this. Largest load I have used thus far is 75A and no problem @ 2kHz.
