I know this has been talked about to death, but I can't seem to find an answer despite looking thru the better portion of the internets, and having an EE friend of mine review it.
I have a super simple circuit. Microcontroller to mosfet that isn't switching a load per say. It's kind of a cascading network of FETs. Eventually the FET will have a load, but not right off the bat.
I've attached an example of how I'm controlling just one FET in the network. The gate goes high and turns the N channel mosfet on. When the gate goes low however, the mosfet stays on despite having a pull down resistor.
The mosfet is a logic level so i'm driving it directly from the micro. I've attached some docs for more info.
Any help is greatly appreciated. My apologies for the crudeness of the schematic.
