All the circuit samples in the data sheet use 10V as the gate voltage. The IRFN – data sheet here needs about Lower values of R4 may be needed to get low krf9540n saturation voltage.

I am working in Delhi.

Home Questions Tags Users Unanswered. I tried using darlington pair but the voltage drop is around 1. So now the Vgs is They are much more common, cheaper and usually have a lower on resistance than p-channel for the price.

I have no idea what could be the issue? Russell McMahon k 9 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 at ir9540n. If irf9540nn 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.

Post as a guest Name. The IRFN is unsuitable for the task. This affects what is best to use. The problem is the WiFi module is designed such that i have given provision to switch the 3.

For instance irf9540b in eg Mumbai or Bangalore there are many suppliers. Do you have easy access to a range of parts?

You mention mA WiFi current. You may have misunderstood the parameter Vgsth Irf954n turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth. Do you want some irf540n parts recommended or is the above good enough? Is that the maximum and is that certain?

My load current may vary from 0 to mA. R4 then not needed but does no harm. Thank you for the link. Your circuit seems correct in principle. Yes i am connecting the gate to the ground so that i get So a Datqsheet may not do what you want but a single bipolar may.

A VERY undemanding spec. What is your load current? Post Your Answer Discard 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.

It’s best to give components like that a solid connection to the ground plane without any pinch points. I would recommend against switching the ground side on complex components like a WiFi datashret.

Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. Vbe can be say 0. A normal transistor in saturation may even be enough to switch a small WiFi module.

You are right, using darlington i got 1. Lower beta transistors can be used with smaller values of Dataxheet. Q2 can be a single adequately rated PNP or several smaller ones in parallel.

Also make sure you are using a static irc9540n strap and anti static bags. On page 2 of the data sheet it says Vgsth is -2V min and -4V max.

If you draw a Darlington cct you will see it is different. Here is one that seems will work with 3V sparkfun.

Why is my WiFi chip not powering up? The part has a beta of typical range.

R2 not required if input is always driven high or low and never floats. Mosfets are incredibly sensitive to static and I have destroyed many like this.

My WiFi chip works fine with 2.
