I'm working on this project with a group, and we have reached a point were we are lost.
The goal that is trying to be accomplished how is a simulation of the attached picture.
What you looking at is four electromagnets (shown in the deep red) that push and pull the magnet in the center. That...
I haven't been able to find any Voltage Regulator ICs that can handle currents greater than 10 amps.
What I'm seeking with this thread is information on pass transistors. Basically how to calculate the values needed.
As a general idea of what I'm trying to accomplish, would it be possible to...
The circuit is this way in order to gain an understanding as to what goes into the making of the chip. In short reverse engineering the ic and putting it on display in an exploded display.
Here's an update.
I've ditched the transistor switch all together in favor of a power mosfet.
The automated part of it has changed as well, it is not a difference amplifier checking the charge across the cell. The problem with feeding it directly into the comparator was that comparator was not...
I would say the 2N3904 its not on your list but if talking about it for the purpose of learn I'd go for something that is going to be cheap to replace if say it burns out.

Are you planning on actually building it?
You may prefer maybe just 4 Op Amp outputs as the scale of logic for the Priority Encoder grows exponentially for every given input, which means your going to need some extra bread boards.
Okay so I've come up with a simple circuit and I'm pretending the battery is a lithium Ion battery.
The 4.2 source is supposed to be a LM317T and the 3.6 battery is the Li-Ion.
So what happens is that the voltage reference is set approximately 99% of full battery charge. When it reaches it...
I've been doing some searching for creating a lithium battery model in mutlisim ( so far with no luck)
But I did find this interesting Google Book,

Alright will do.
Its the Op Amp part I'm a little stuck on because as I've seen in Google searches it involves a sense resistor which I'm afraid will effect the constant voltage and current parameters I'm trying to work to.
I've been looking all over the internet(Google) for some idea on making a lithium battery charger, or the basic principle behind it without the need of complex micro controllers.
What I've been finding is completed designs but not really any in-depth theory or formulas.
What I'm basically...
Re: How can I set up a binary counter to count in bcd?
I was able to correct the propagation delay by using a small cap(104) connected from the output of the AND gate to ground.
