HI

I have an issue on BQ27427

During charging, the current is showing negative.

During discharging, the current is showing positive.

I have checked by reading 0x10, 0x11 register

I am using BQ24250 as the charger.

Attached is my circuit.

Regards

Kok Keong

    Hello Kok,

    I have the battery gauge marked up, yellow is good but the purple I wanted to confirm that you had your load attached on that line. I am not on charger so I would also recommend to ask them to check your schematics as well. However it does appear that you did do the schematics correctly and I would check to see your hardware to see your connections are done correctly from the battery to the load as well.

    Thank you,
    Alan
