Unless you're using it to invert the logic - could be useful for that. If you want Hall output low to mean MOSFET active and vice versa, then use the NPN. Otherwise I'm with Max and Ron.
Hi everyone and thanks for the suggestions. this circuit is supposed to drive one or 2 coils as electromagnets, in short it's a dc motor control. My concern it's about the resistors that I should use between those components. I'll upload the circuit so you will have a better understanding.That device shows as a legacy product now.
Take as 10k resistor to +ve from the sensor output pin and feed output into a mosfet gate.
That is a logic level Mosfet which you don't necessarily need for 12v supply.
Cool. I sort of enjoy reverse engineering circuits and creating schematics, so I'll see if I can do that here.Probably the circuit I made on paper sucks! Lol this is the working one! The resistor are the same as the one I gave early. If I can do anything to improve it, will be good!
Can you measure the voltage (relative to ground) at the MOSFET gate and also across the motor when the motor is running?Hi, all is connected but I don't get too much power to the eletromagnet as when I conect it directly to the battery... anybody knows what I may do to have more power? May a condenser? Thanks
