Default Atmega8 to drive a motor

Hi,
I looking at driving a half amp 12v pump from an atmega8 or 168
through a mosfet. What is the recommended mosfet for this application? I
have done heaps of snooping online but am getting quite bamboozled.

Thanks in advance, regards

Darren

how many volts VCC to the atmega? (how many to ground?)

what's the stall current of the pump?
or how high does current spike when starting?

are you switching low side or high side of the pump supply?

12V negative to ground?

Bye.
