On page 24 of the part datasheet: www.ti.com/.../bq24618.pdf the battery detection flow chart and all the info below it (including the graph) implies that if VFB is above VRECH then the battery is absent. However, in the upper right-hand corner of the flow chart there is a paragraph that states: "The battery detection routine runs on power up, or if VFB falls below VRECH due to removing a battery or discharging a battery". If the VFB below VRECH means that the battery is present, why would removing the battery bring VFB below VRECH? Is there something I'm missing?
Thanks,
