R4 then not needed but does no harm. 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.

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

You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth. BCxx has a typical saturation voltage of about 0.

Vbe can be say 0. BCxx7 data sheet here See Fig 9. Home Questions Tags Users Unanswered. Are you doing that?

Resistor values are liable to be about right – play as required. 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. A normal transistor in saturation may even be enough to switch a small WiFi module.

The connection is as follows Source 3. If you draw a Darlington cct you will see it irf540n different. A VERY undemanding spec. Sign up using Facebook. They are much more common, cheaper and usually have a lower on resistance than p-channel for the price.

Any help would be appreciated. I have no idea what could be the issue? Thank you for the link. Thank you for understanding my problem.


The problem is the WiFi module is designed such darasheet i have given provision to switch the 3.

You are right, using darlington i got 1. I am working in Delhi. R3 is ‘or safety’ to ensure Q2 turns off.

Is that the maximum and is that certain? Do you want some specific parts recommended or is the above good enough?

The IRFN – data sheet here needs about Russell McMahon k 9 This affects what is best to use. Lower values of R4 may be needed to get low enoughy saturation voltage. Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. Q2 can be a single adequately rated Datasheet or several smaller ones in parallel.
