That one is not too bad, Rds(on) is quoted at 70 milliohms @ 4v 10A, 50 milliohms @ 5v 12A.
Bear in mind that the power dissipation is I^2*R. So at 10A and 50 milliohms this is 5W and you will need a heatsink. You might consider something like http://uk.farnell.com/stmicroelectronics/stu95n2lh5/mosfet-n-ch-25v-80a-ipak/dp/1752195 which has Rds(on) of 5 milliohms typical at 5v and 10A, so won't need a heatsink as long as you drive it hard enough to switch fast (indeed, that device is not in a TO220 case, so heatsinking it is not easy). Or you could play safe and go for http://uk.farnell.com/stmicroelectronics/stp85n3lh5/mosfet-n-ch-30v-80a-to-220/dp/1752172 which comes in a TO220 case.
