BQ25606: charging current can only reach 1.7 A

Part Number: BQ25606

Hi team,

Here's an issue from the customer may need your help:

The device can only be charged to 1.7 A, and the constant current can only last for 10 minutes when the battery is discharged.

Could you help check this case? Thanks.

Best Regards,

Cherry

    Hi Cherry, 

    The device should be able to charge up to 3 A. What is the customers desired charge current and what is the value of R_ICHG they use to set charge current?

    Multiple factors could lead to the charge current being below the set value. Please have the customer provide the operation waveforms such as VBUS, VBAT, VSYS, ISYS, IBAT, STAT so we can better diagnose what is happening. 

    Regards,

    Garrett
