BQ25713: BQ25713 charge current higher than set

Star Xu

Part Number: BQ25713

Hi

My customer use BQ25713 design the schematic. I2C has set the maximum and minimum charging voltage and the maximum charging current, but the actual running current is higher than the maximum current? At this time the board is very hot, My input voltage is 12V.

Attached the schematic for your reference.

Waiting for your reply.

Thanks

Star

    Hi Star,

    In order to find our the root cause, could explain more clearly under which condition the board is very hot:

    1, How much charging current and charging voltage are set? What is the practical running current? 

    2, What is the input current for this test and how much system load is added?

    3, What is the battery voltage and minimum system voltage setting for this test?

    4, Do you have thermal camera to capture the hottest spot on board?

    Regards
