I wanted to design a circuit to select a battery pack between three packs. batteries nominal voltage is 48V and there are two main packs and an auxiliary pack for failure situations. by powering on the system one of the main packs should be used until its voltage drops to 40V and then the second main pack should be inserted into the circuit. So, I need a prioritized ideal diode for achieving the mentioned specification. I wonder if you could guide me to select a suitable component in this regard.
