I’m looking for a circuit that can protect 3-6 Volts AA Batteries when a short-circuit happens. When the short-circuit happens, a second circuit (LED blinking) must be triggered and the batteries must be protected. The goal is that the LED won’t stop blinking until the short-circuit is undone. Could someone give me hand at selecting cheap suitable options for this application? E-fuse, p-channel mosfet, x2 transistor arrange, Ideal diodes, a Battery protector CI? The only requirement is that the circuit also operates when two 3Volts AA batteries are connected in series.
