My dilemma is am new to this field so is there any other better power MOSFET for high voltage switching application and driver for dahasheet same. That just will make your circuit much easier and save you a transistor and resistor.

Sometimes a MCU seems to be driving a mosfet correctly, but only a careful measurement will show the mosfet is not getting fully turned on, overheating and wasting power.

Backyard controller design Eric’s Arcana and RiderX. R1 is just there to limit the current through the gat, coming from a microcontroller pin. For a mA current you then need a seriesresistor of 33 Ohm. The is somewhat better: Yes im using Arduino to control the circuit. Try just to test without the converter, 3.

What type of step up converter are you using? You are limited to a current of about mA. The two P-channel mosfet will be driven by transistors. Thank you for this very good explanation. Or am I overlooking something? This site uses Akismet to reduce spam. Whats about this, I have check in the datasheet and seems to work very well at TTL levels even with a lot of Amps.


The 20 Volt you probably saw in the datasheet, but that is the max voltage on the gate. The irf doesnt need 20 Volt tu dtasheet on. This will need a good heatsink if the load is datahseet for more than a second or two, but it is no issue if it gets millisecond pulses every few seconds.

Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)

The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement. Is this what you mean? For a Datadheet it is a bit on the edge. I bought it and it works with Arduino. Good luck with your project. The battery is ok and gives a steady 4 volts. The datasheet mentioned a current between 21 Amperes Amperes for driving led.

More and more cheap Mosfets.

I presume you are aware of the designcriteria of an H-bridge and the chances of shorting your PSU if you dont do the switching correctly. But if it is working for you, that is good. Anyway, depending on your circuit, I am not sure if you need a logic level P fet as often there is transistor driving the mosfet.


It is not expensive: Thanks in advance, Ruben. Thanks, perhaps we are just discussing terminology here.

I am using this converter: The dissipation then is 5x5x0. Sorry, your blog cannot share posts by email. It doesnt look dedicated to a steppermotor though, more to drive a rgular DC motor. Well, you would need to put an inverter before the circuit i provided, either by a logical gate or with yet another transistor. Who can tell me what should I improve i my schematic?

The input capacitance is best chosen as low as possible. Somehow Logic P channel mosfetsarent as plentiful.

Well what an amazing article. It already switches on at much lower voltages, albeit not completely, but the optimal voltage is around Volt. The only caveat using those AO parts, is their size: Thank you for the clear explanation.
