hello guys
i repair a ups recently and i was surprised they are using an op amp(LM324) and i wasn't quite sure why they are using it so i tracked the connections using my microscope.
I came out with a schematic which you will find in the attachments.
MY question is what might be the function of the op amp here ?
Also kindly post a quick analysis for the circuit.
Notes:
1-pin 4 and 11 are the power supply pins.
2-If you find something illogical, tell me and i will review the pcb to correct the error in my schematic.
