Re: battery charger
Is there sufficient voltage difference between the source and drain to turn fully on and off? I thought that a MOSFET requires a Vds of a couple volts, NMOS or PMOS... is this wrong?
Plus as the batteries charge, the voltage will increase. The FET would need to be able to stay turned off as the battery voltage increased to (and possibly past) the regulated +5v source.
When I have a bit of time I'm going to play around with a circuit... but I would appreciate some input on this.
Thanks
