Could someone help me with designing a IC in Multisim.
I am a complete Newbie to
electronics and Multisim and am trying hard to teach myself, if someone
could show me what this kind of circuit would look like in Multisim
then I think it would be a huge help.
The project is a solar charger charging
4AA NiMH batteries which at night turns the load on, the load is 36
LEDs connected in parallel. I know they will all light up as I
have done the test and they all light up and draw 3.6 V and last
for about 8 hours.
So I want to build a IC that switches the
load on at night and I want to use the PVC's as the switch so at night
the circuit is turned on and during the day it is turned off and the
batteries start charging. These kind of devices can be bought at
most hardware stores so it's not a unique idea.
If some one could mail me a .ms file I could load it up and understand how it all works and it would set me on my way.
The best way is to use the primative models i.e 2n2222a, or lm741, >>>> devices that have models defined in the master database and use them in a "schematic" to build a "spice" model.
Basically the full schematic would run as a "subcircuit" and route to your IC pins that your designing and will interlink with the subcircuit as the PHYSICAL pins to the device your trying to design. I've done that for the LM3914 device and it works very well.
