BQ24610: BQ24610 LED CHARGE NOT OFF WITHOUT AC/DC ADAPTER INPUT

Part Number: BQ24610

Tool/software:

Hi guys,

I'm using BQ24610 with BQ40Z50RSMT-R1 for Battery Management. When I plug the AC/DC adapter input, BQ24610 is charging and the red LED is light, which means STAT1 is on, STAT2 off.

When I unplug the AC/DC adapter, the red LED is still on, which means STAT1 is still on.

 I attracted schematic. So please help me resolve this problem. 

Many thanks,
