i am using the Maxim 6643 for a cooling project. the maxim PWM output drives a FET, but its not clear to me if the FET needs to be one that is rated as having logic level FET gate. my project uses fans that are 30A at full power.
IR has a FET that has logic level gate (http://www.irf.com/product-info/datasheets/data/irlz44n.pdf). does "logic level" mean full rated current @ 5v on gate?
do you see a issue driving two of these FET gates directly from the Maxim? when is a FET gate driver needed?
