can anybody help me figure out what transistor would work to run a 12v 19a solenoid valve from an arduino pin?
any help is greatly appreciated.
any help is greatly appreciated.
can you suggest a model of logic level FET and driver that would work for this?if you are really throwing down 19 Amps, I would suggest a MOSFET driver between the controller and the FET. You can then use the 5V (or whatever it is) control signal and drive the FET with 12V for lower Rds(on) and there will be no chance of damaging the controller pin.
For low speed switching (Less than 1Khz):im not sure how to calculate what ratings i need for the logic level FET. Do i need an RDS equal to the power of my pin?
