BQ24045: BQ24045 charging detection problem

Part Number: BQ24045


Hi Ti Team,

we use the BQ24045 charging ic in our design.

Due to some problem charging ic pin 8 is set as Low state after connect the battery to the pcb.

for that we also check the different battery voltage level and also put battery as long time like 3-4 hours but after also ic not detecting the battery and pin 8 is set in Low state they not change in High state after connect the battery.

our battery specs. is 800mAh,4.2V.  

so please you have any suggestion let me know?
