Part Number: BQ40Z50

HI everyone I have an interesting problem with my design.

I am using 3P1P battery pack with 18650 GA cells and a bq40z50 standard scheme nothing special.

The battery is for optical camera and when the camera starts the bq40z50 is entering reset mode and the cammera cannot compleate the rising and shuts down. 

i attached here a scope picture of the moment of the pushing the on button in the camera and the voltage drop it sees. 

also attached CSV file of my bq40z50 configuration7357.bq40z50.gg.csv i am using R5 SW.

also i would like to mentioned that first i thought about some in rush on the ground plane i reworked the layout to a better one and it did not help.

    Hi Stas,

    Would it be possible to receive a log file of this occurrence happening within the gauge?

    Also, taking a look into the sent log file, please set the DA Configuration for this gauge to match the 3S1P stated above. This would be done by setting the CC1 bit below:

    Regards,
