You are right, using darlington i got 1. Lower values of R4 may be needed to get low enoughy saturation voltage. Sign up using Email and Password.

So a Darlington may not do what you want but a single bipolar may. Sign up or log in Sign up using Google.

But the voltage drop is around 0. Yes i am connecting the gate to the ground so that i get A VERY undemanding spec. Normal transistors BC is switching only mA. R2 not required if input is always driven high or low and never floats.

Do you have easy access to a range of parts? It’s best to give components datasheeet that a solid connection to the ground plane without any pinch points.

A normal transistor in saturation may even be enough to switch a small WiFi module. Why datasheeet my WiFi chip not powering up?

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. The only problems are: BCxx7 data sheet here See Fig 9. This would not be good. The falling poutput voltage “steals” drive from the input so Vc2 out can never be less than 1 x Vbe or more.

Instead of switching 3. You mention mA WiFi current. You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth. Are you doing that? Post as a guest Name. I may need around mA for my WiFi. I am working in Delhi. Also make sure you are using a static wrist strap and anti static bags.

Vbe can be say 0. Here is one that seems will work with 3V sparkfun. The IRFN – data sheet here needs about I tried using darlington pair but the dwtasheet drop is around 1.

What is your load current?

Any help would be appreciated. BCxx has a typical saturation voltage of about 0. The connection is as follows Source 3. I have no idea what could be the issue? Your circuit seems correct in principle.

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 irf9504n. A wide range of small bipolar PNPs will dataxheet.
