This affects what is best to use. Vijay Anand Chandrasekaran 45 1 Here is one that seems will work with 3V sparkfun. The connection is as follows Source 3. A datashwet transistor in saturation may even be enough to switch a small WiFi module. I have to go with high side switch only.

I am working in Delhi. I may need around mA for my WiFi. A VERY undemanding spec. Your circuit seems correct in principle.

If you pick through a bin of these you MAY find some that work somewhat better than others and some that MAY work well enough for you – but maybe not, and this cannot be guaranteed.

My load current may vary from 0 to mA. Q2 can be a single adequately rated PNP or several smaller ones in parallel. So now the Vgs is Mosfets are incredibly sensitive to static and I have destroyed many like this.

If you look at graph in the datasheet of current vs gate-source voltage Fig 3 and extrapolate down to 3V you will see that almost no current will flow. Sign up using Email and Password.

Although they usually seem to fail on rather than off. Do you want some specific parts recommended or is the above good enough? Why is my Dataseet chip not powering up?

It’s best to give components like that a solid connection to the ground plane without any pinch points. Any help would be appreciated. Also make sure you are using a static wrist strap and anti static bags. So a Darlington may not do what you want but a single bipolar may. Sign up using Facebook. Yes i am connecting the gate to the ground so that i get Vbe can be say 0. Can you please suggest me some MOSFETs specific parts which are locally available or which people often use for their research?

The part has a beta of typical range. You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth. Thank you for understanding my problem.

If you draw a Darlington cct you will see it is different. Instead of switching 3. Post as a guest Name. The IRFN – data sheet here needs about Email Required, but never shown. Thank you for the link.

Resistor values are liable to be about right – play as required. Sign up or log in Sign up using Google. There are many Gnd pins in WiFi chip and they are all connected so i have no option of disconnecting all the ground pins to make a low side switch. I dqtasheet using darlington pair but the voltage drop is around 1. You are right, using darlington i got 1. You mention mA WiFi current.

I have no idea what could be the issue? Lower beta transistors can be used with smaller values of R4. To do that with eg 0.
