To tackle this we should use a current limiting capacitor, I have a used a value of here. Here is the part of the code where the delay is not working, I set it up to eliminate any outside factors: Current flows out through Source. When you turn on a Mosfet by supplying the required voltage to the gate pin, it will remain on unless you supply 0V to the gate.

When a gate voltage is applied these pins gets closed. Perhaps I should post this in a separate topic, but it is a continuation of the project addressed above and may relate to the way that I am using power. You alo need to check the data sheet to see how well it performs with only 5v on the gate.

This mosfet can drive loads upto 23A and can support peak current upto A. Irfa datasheet pdf So my irfaa question is datadheet is the proper method for giving a motor more and less power? Tying the gate to the source with a high value resistor is a good plan as people have mentioned, such as 1Mohm, so that its safely off until setup has run. I maybe could have solved this with proper use of diodes, but after a few hours of messing around, I was still stumped.

I looked at the spec for a the IRF, and it looks like it needs 10V to switch it on. Both lowered resistance, but still kept maybe 2k ohms. Here are some examples, to illustrate what is available http: Current flows in through Drain. Meaning, they can be turned on or turned off by supplying the required Gate threshold voltage VGS. You simply need to drive its gate from a NPN transistor with pull-up to 12V — however the pump might be putting spikes onto the 12V rail which might be an issue.

Please note that some Vishay documentation may still make reference to the IEC definition. TL — Programmable Reference Voltage. The water pump is rated at 12V and 2. You might need something to increase the gate voltage for lower internal resistance.

Do you ratasheet what I did and turn the power on and off really fast? So if you are looking for a Mosfet to switch applications that consume high current with some logic level devices then this Mosfet will be a perfect choice for you. The below circuit shows how this mosfet behaves when the Gate voltage is applied 5V and not applied 0V. The last problem that I had was that the thing would overheat pretty bad after a datasheeet a few moments of the motor being on.

To avoid this problem we should always use a pull-down resistor R1here I have used a value of 10k. TOP 10 Related.

Tying the gate to the source with a high value resistor is a good plan as people have mentioned, such as 1Mohm, so that its safely off until setup has run. Such statements are not binding statements about the suitability of products for a particular application. Perhaps I should post this in a separate topic, but it is a continuation of the project addressed above and may relate to the way that I am using power. Available in To package Note: You simply need to drive its gate from a NPN transistor with pull-up to 12V — however the pump might be putting spikes onto the 12V rail which might be an issue. If not, what do you do, and again, what are the proper components to use?

Use Google Search box in upper right side of this page. Remember MOSFETS have an effectively infinite input resistance so if the gate is left floating it will pick whatever ions are floating around in the air, respond to any slight leakage currents that might be present. If not, what do you do, and again, what are the proper components to use? MarkT Brattain Member Posts: You might need something to increase the gate voltage for lower internal resistance. How to use IRFN: I maybe could have solved this with proper use of diodes, but after a few datasgeet of messing around, I was still stumped.
