Hi Folks!
This will be my first time posting on this forum (or any forum for that fact), I normally get all my information from already existing posts, however I have decided to come out from living under a rock and join the community, maybe help in answering some questions.
Im a self taught electronics engineer, I have been at it for about 2 years now
Anyways I am designing an analogue Balance charging system. I am using PNP transistors to transfer the current to the next battery if that battery in the series is overcharging then the rest. Now this is good and all but it still leaks a little bit of current when it is switched off because I am using a MOSFET to switch the PNP on and off.
I also dont want the balance charging system to make calculations in the first few seconds when the charger is first turned on because the batteries take a while to get to their "charging settle state" voltage.
So now I am going to use a combination of a SPST electromagnetic switch, PNP and MOSFET to do the job.
SO! what is the smallest and cheapest SPST switch that you can buy? or is there a better way of doing this?
Cheers!
Mathew
