N-Channel mosfet with TTL
MOSFET Driver 8V to 48V Power. The input threshold is TTL/CMOS compatible but may. MOSFET, which returns through a low valued drain sense resistor to supply. I have been trying to make a pulse generator using Arduino Uno Rev 3 to drive MOSFET driver, which then drive MOSFET, by using TTL signal from Arduino. (5V in as Vcc and about 4.8 V in as TTL signal) I am currently using Arduino Uno Rev 3 to supply voltage to MOSFET driver, IXDN614PI, which is connected to a MOSFET. I'm trying to drive a 12V valve with a TTL signal from my motion controller. After various suggestions, I'm trying a mosfet to drive the circuit. LTC4441/LTC4441-1 1 44411fa Typical applicaTion FeaTures DescripTion N-Channel MOSFET Gate Driver The LTC®4441/LTC4441-1 is an N-channel MOSFET gate driver that can supply up to 6A of peak output current.

I'm trying to drive a 12V valve with a TTL signal from my motion controller. After various suggestions, I'm trying a mosfet to drive the circuit. Specifically, I am using this mosfet: http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=60832&Row=533489&Site=US
I have the TTL connected to a 10k resistor, which then connects to the gate. The source is connected to the negative end of a 12V power supply. The drain is connected to the the negative lead of the valve, with an ultra fast 100V axial diode connected in parallel with the valve. The positive lead the valve connects to the positive end of the 12V power supply.
When I power on the power supply, the mosfet appears to be already conducting, as the valve begins to dispense its fluid. Sending the 5V TTL signal appears to have no effect. What did I do wrong?
