I use IRF2804's to switch various current loads up to 50 A, using a Micrel 5014 (or 5015) driver. The driver can be easily controlled with a signal directly from the uC. The control threshold is about 2 V. The 2804's have a really low on-resistance, only 2 milli-ohms, and I don't use any heat sink at all up to 10 A or so. At 50 A I use a modest heat sink, but have yet to even feel it get warm. They are spec'd up to 75 A continuous. Pretty amazing little gizmos.
