Hello guys! First time here!
I am currently working on a power supply for a medical application where I have to charge an NiMH 12V battery when the voltage across it is lower than a certain point. So, for that matter, I am using a non-inverting Schmitt trigger, that is to make sure to charge only when necessary and bringing the battery back to its nominal point. The problem is, I am not sure if the LM317 constant current source (200mA) will negatively affect (that is fry!) the LM358 when it is not charging the battery (when the battery GND is not connected). I ordered the PCB, but now that it's on the way, I am having a little doubt over it. Could you guys tell me if I messed up on that part?
Thanks to all of you,
Jeff
