Here is one that seems will work with 3V sparkfun. Yes i am connecting the gate to the ground so that i get Q2 can be a single adequately rated PNP or several smaller ones in parallel. Post as a guest Name. On page 2 of the data sheet it says Vgsth is -2V min and -4V max.

The only problems are: For low saturation voltage both Darlington pair and Sziklai pair are bad because they “steal their own drive” as they turn. I tried using darlington pair but the voltage drop is around 1. It’s datwsheet to give components like that a solid connection to the ground plane without any pinch points.

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.

I would recommend against switching the ground side on complex components like a WiFi module. They are much more common, cheaper and usually have a lower on resistance than p-channel for the price. This affects what is best to use. R3 is ‘or safety’ to ensure Q2 turns off. The falling poutput voltage “steals” drive from the input so Vc2 out can never be less than 1 x Vbe or more.

You mention mA WiFi current. datawheet

Lower values of R4 may be needed to get low enoughy saturation voltage. Thank you for the link. Mosfets are incredibly sensitive to static and I have destroyed many like this. Best likelihood, based on all evidence and the data sheet, is that even though your load current needed is tiny – the Vgsth value is so far above your drive voltage that it just sits and grins iirf9540n you.

All the circuit samples in the data sheet use 10V as the gate voltage. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

The IRFN – data sheet here needs about A normal transistor would do and i experimented too.

Why is my WiFi chip not powering up? Do you have easy access to a range datasgeet parts? But the voltage drop is around 0.

Russell McMahon k 9 My WiFi chip works fine with 2. Email Required, but never shown. Vbe can be say 0. So a Darlington may not do what you want but a single bipolar may. The part has a beta of typical range.

Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. Thank you for understanding my problem. I have no idea what could be the issue?

Is that the maximum and is that certain? Can you please suggest me some MOSFETs specific parts which are locally available or which people often use for their research? Your available Vgs max is Sign up or log in Sign up using Google.

I have to go with high side switch only. The problem is the WiFi module is designed such that i have given datasgeet to switch the 3. For irf9540nn if in eg Mumbai or Bangalore there are many suppliers. Your circuit seems correct in principle. 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.

Lower beta transistors can be used with smaller values of R4.
