I'm using the DC2039 in order to test the LTC4015 for charging LiFePO4 battery and interfacing the load voltage supply through VSYS. The problem is that measuring the current consumption of my load with a external voltage supply the current is above (15 A) the VSYS output current (10 A). Reading the LTC4015 datasheet it only mentions that changing the RSNSB you can increase the MAX_ CHARGE_CURRENT but never mention the maximum current capability at VSYS. How can I increase the VSYS current output ? I was thinking by tying the VIN and VSYS pin of two LTC4015 , like two LTC4015 in parallel but just one of them wil charge the battery. Is this convinient or possible? if not, which could be the solution to increase the output current at VSYS? Or the output current value depends of the MOSFET (ideal diodes) of the board?
