In my circuit making experience when faced with a problem wherein I need to switch a high current load with a MOSFET, my go-to solution has always been finding a better MOSFET that can handle the current and has low enough resistance in order for thermals to become not a problem.
I am exploring the option of using 2 (possibly more) same model MOSFETs in parallel driven by the same MOSFET driver to guarantee simultaneous turn on. Is this a good idea?
Paralleling MOSFETs in my opinion would solve two problems at the same time. Paralleling them means that I would get theoretically half the "on" resistance which also means that thermals would also be reduced.
A counter argument to this would be if the MOSFETs don't turn on at the same time, for a brief period of time one of the MOSFETs will be subjected to currents possibly higher than its rating. A solution to this is have both MOSFETs be driven by the same driver pin. This will slow the turn on/off time depending on the capabilities of the driver. A further solution is to choose a MOSFET that carries the full current in the first place, meaning you are just solving the thermal problem.
In my opinion I have a good idea, but what bothers me is I have not seen any circuits that do this. That implies that my thinking might be flawed.
What are your thoughts about this?
