I'm designing a system that can draw more than 4A from a LiFePo4 cell. I want to charge the cell using ADP5063. The datasheet states Continuous Drain Current as 2.1A. So I want to route discharge power around the charger when the system is in discharge (battery powered) mode. How can I safely connect the cell to the system load (boost converter) and the charger in parallel? I imagine disconnecting the cell+charger from the system using a gate MOSFET when wall power is available. Do you have a recommended / best practice circuit for this or is it a bad idea in general?
