TPS25750EVM: 2S battery charging current is limited 0.2A

Part Number: TPS25750EVM
Other Parts Discussed in Thread: TPS25750, BQ25731

When I test TPS25750EVM board, I encountered a problem. I have shorted D2.

If I set TPS25750 in sink or source mode, 2S battery_2A charging current, the charging current is limited to 0.2A. I have tested for many times.

One of our customer will use TPS25750 under 2S battery condition.

But 4S battery, the charging current will be right as the tool setting. I have tested 2A 3A and it operate normally.

Could please give me some advice?
