I am trying to use a TP5100 for 1S Li-po charging. In my application, the 5V input is always connected to a battery charger IC. My system consumes 2A continuously.
When my battery is fully charged, it should have a voltage output of 4.2V and virtually no current, and the 5V input stays connected.
How is the system current is supposed to be drawn through the TP5100? The charger IC would not give out any current in this case, right?
