THere are a bunch. But the LM5111/LM5112 or TPS812 (and the others in the same datasheet) will do it. THese are low-side drivers only. For high-side you would need either a floating (isolated) DC-DC converter, or more economically an IR2010 or some other IC like it.

Rds(on) is spec'ed at 10V. Vgs=+-20V (+-30V in the datasheet I looked at) is the absolute maximum limits, beyond which you may break down the gate.
What are you driving with the RFP460? Many applications just need a simple level translator, which can be done with an NPN and a couple of resistors.

the application is to drive dc-motor by PWM,the MOSFET is connected in low side,the PWM signal come from PIC output which is 5V so i need the gate driver to to drive the MOSFET gate from the PIC output.
the current will go through the MOSFET is typicaly 7-8A
i dont know how to determine the frequency?and which frequency you mean?
sorr for the lake question.
about the duety cycle for PWM
i have motor with 220 DC and ineed to varey the speed from 0 to full speed (2500rpm)
so the d.c will varey from 0 to 100%

i dont know if that you ask about
but in pwm i will varey the ton with constant T
so i think the frequency is constant
but i dont know whats the difference if it high or low frequency
