Constant current from AA nimh (down to 0.8V)
Hello.
I'm trying to design a circuit to drain a single AA nimh battery at a constant current down to 0.8V.
I was going to try an LM317 or an LM431, but they're voltage references are 1.25V and 2.5V, so since the battery needs be drained down to 0.8V those two ICs won't work -- right?
I'm trying to build this as cheaply and with as few components as possible. Any ideas?
