Will Vout follow Vin when no battery is present when using bq21040 ?

Battery detection performs when no battery is connected. Please see figure 28 in the datasheet.

Thanks Jing Zou. I am not sure I follow. Figure 28 in the datasheet shows regulation of Vin ?

It is a typo. Please see figure 20. Detail description for battery detection routine can be found in section 8.4.9.
