I''ve search for a solution to my problem both on this site and on Google but I did not find a complete and adequate response. I need a circuit that switches two 12v sources (one that comes from a lead-acid battery powered by
The Schottky diodes prevent backflow to the LiFePO4 battery bank. Underway, off shore power, the Odyssey battery terminal voltage rapidly drops to 12.8 volts, and the LiFePO4 batteries (Bank 2) pick up the entire load until a transition occurs at 12.8 volts, where the Odyssey battery begins to take up the load.

The 48V battery switch reference design shows an implementation of an air-cooled high current disconnect switch for automotive 48 V batteries with hall sensor and shunt based current
Medium power lithium-ion batteries are suitable storage systems for providing islanding capabilities , , . The main functional requirement of energy storage systems (ESS), when used in microgrids, is to optimize the power flow, usually in terms of energy costs.
Many loads on the 48V power domain have a big capacitance like a DC-link capacitor or EMC filter at their input. Switching onto an uncharged capacitor will cause a high inrush current, limited only by the ESR of the capacitor as well as other resistances (cables, connectors, battery) in the system.
Channel B drives the MOSFETs for the DC-link precharge circuit. In order to improve functional safety there are two diverse methods implemented for current monitoring and overcurrent protection – shunt based current sensing on the low side and hall based current sensing with the TLE4972-AE35D5 on the high side.
The green curve marked “Short” shows the trigger for the short circuit switch. When the short is applied, the load current (violet curve “ILD”) starts to rise linearly. The current slew rate is determined by the cable inductance. As soon as the overcurrent threshold is reached, the gate driver 2ED4820-EM
