BQ24075: My charging current is limited to 0.47A

vishal kakade22

Part Number: BQ24075

I have set the fast charging current to 1.3A, and maximum input to 1.4A. But my charging current is limited to 0.47A. I have tried changing the charging current but still, the charging current is limited.

Please tell me why is this happening. My batteries can take maximum charging current of 1.5A. And my adapter can also provide enough current.

Hello,
What is the input voltage? Also, is the charging current always at 0.47A or does it start at a higher value then stays at 0.47A?

I am using a 5V,2A mobile chrger. And charging current is 0.47A from beginning of charging. I tried using a different battery, but the error remains same.

Hi,

I have found the solution, it was happening because of reverse comination of EN1 and EN2.

Thanks and Regards
