my idea is to create a “general purpose” board with a MOSFET gate driver and the appropriate MOSFET for it. This board should be able to work with the logic level signal output of 3.3V/5V and have the capability to drive LED strips, PC fans or kind of “anything” that needs a little bit more juice and is controllable via PWM.
So I found the UCC27517 which is able to source and sink 4A Peak.
Now my question is, what are those 4A linked to.
The maximal Drain/Source current of the MOSFET?
Or is that the total load that is coming up when the MOSFET gate is driven?
Should I not be able to drive a logic level MOSFET directly from the output of the microcontroller?
What is the driver internally supposed to do better than the direct output of the microcontroller?
And yes, I know there are plenty of resources on google that may explain the topic, but those brought me just more confusion.
