R4 then not needed but does no harm. Home Questions Tags Users Unanswered. Sign up or log in Sign up using Google. This affects what is best to use. Lower values of R4 may be needed to get low enoughy saturation voltage.
I tried using darlington pair but the voltage drop is around 1. Q2 can adtasheet a single adequately rated PNP or several smaller ones in parallel. So a Darlington may not do what you want but a single bipolar may. While figs 1 and 2 suggest the 3.
IRF IRFN Power MOSFET P-Channel 23A V
BCxx has a typical saturation voltage of about 0. To do that with eg 0. Russell McMahon k 9 On page 2 of the data sheet it says Vgsth is -2V min irf954n -4V max. A normal transistor would do and i experimented too. Can you please suggest me some MOSFETs specific parts which are locally available or which people often use for their research? R2 not required if input is always driven high or low and never floats. If you draw a Darlington cct you will see it is ifr9540n.
Do you want some specific parts recommended or is the above good enough? For instance if in eg Mumbai or Bangalore there are many suppliers. They are much more common, cheaper and usually have xatasheet lower on resistance than p-channel for the price. 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.
What is your load current? The IRFN – data sheet here needs about This would not be good. The part has a beta of typical range. Is that the maximum and is that certain? Email Required, but never shown. However, the graphs are for typical datashet. A normal transistor in saturation may even be enough to switch a small WiFi module.
You are right, using darlington i got 1. I have to go with high side switch only. Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop.
Yes i am connecting the gate to the ground so that i get Thank you for the link. Dataheet may need around mA irr9540n my WiFi. I am working in Delhi. All the circuit samples in the data sheet use 10V as the gate voltage. Resistor values are liable to be about right – play as required. Sign up using Email and Password. Vbe can be say 0. Your available Vgs max is Vijay Anand Chandrasekaran 45 1 R3 is ‘or safety’ to ensure Q2 turns off.
It’s best to give components like that a solid connection to the ground plane without any pinch points. But the voltage drop is around 0.
IRFN – Infineon Technologies
The only problems are: I am able to get it in bangalore and mumbai but they are taking long time for shipping say weeks. Are you doing that? The IRFN is unsuitable for the task.
IRF9540N MOSFET. Datasheet pdf. Equivalent
A FET becomes attractive: Any help would be appreciated. My WiFi chip works fine with 2. Why is my WiFi chip not powering up?
I have no idea what could be the issue? Do you have easy access to a range of parts?
