BQ24610: 12.6V Battery charging buck converter charging status issue

Hello Mahesh,

Are you using your own design or an EVM?

If you are using your own design can you provide your schematic?

Best Regards,

Christian.

Hello Christian, 

We are using our own design. I won't be able to provide you the schematic from our system. I can mail you if you give your mail id. We are using 500K and 100K feedback resistor for 12V full charge.  Also, when I am discharging battery completely and I am charging it again that time it is not going into charging mode. Kindly help 

Hello Mahesh,

Yes, provide the schematic through email: c-moyer@ti.com

Best Regards,

Christian.

Hello Mahesh,

I'm reviewing your schematic, I will provide feedback, after I gather more information.

Best Regards,

Christian.

Hello Mahesh,

What are you using as your pull up rail for STAT? It's not clear in the schematic.

Best Regards,

Christian.

Hello Christian, 

We have adaptor supply and 1K0603F resistor in that circuit

but when i suddenly remove the battery in between still charging status LED remains ON and it is taking 0.22A current from main power source.

Does this happen every time you remove the battery?

What is the voltage on the battery terminal when battery is removed?

What is voltage on VFB pin?

Best Regards,

Christian
