I have a Lipo battery in my circuit with a LM317-based charger. Don’t judge me please It is a through-hole prototype before going to SMD parts.
I’m worried about what happens when the battery completely discarges and get damaged.
How can I protect the battery? Can someone suggest a simple way to disconnect the battery electronically at a certain voltage level?
I’m thinking either a P-channel logic level MOSFET on the positive supply or an N-channel on the return (before the 1 ohm current sense resistor).
Any other suggestions?
