BQ24192: Battery drop issue while discharging

Part Number: BQ24192

Hi TI Team,

We are using BQ24192 charger chip in our custom design. 

When our system is drawing 2.5A constant current and if we remove the external input, the system draws 2.5A current from fully charged battery.

At that time, We are seeing 250mV difference between the voltage at battery terminals and voltage at system output (VSYS) which in turn causes the reduction of available voltage to the entire system.

To clarify, voltage at battery terminals is 250mV greater than that at system output.

Please help us to debug this issue further.

Note: Battery was full charged when migrating from external input to Battery.
