Part Number: BQ40Z80

the sus turbo current is very big, but i see the RTM the OCC1 is trigger by current() not the turbo current ,right?

In order to exclude the contingency of welding， sold three board ， the result is all the same.

thank you very much!

Hi Yanbin,

OCC1 trips when Current() is continuously larger than or equal to the OCC1 Threshold for the OCC1 Delay Duration. Please ensure that this condition is not met to prevent OCC1 tripping.

If the issue persists, please send a log in 1 sec intervals of the failure. Also, could you provide a gg.csv file that hasn't been opened and saved in excel? Thanks!

Sincerely,
Bryan Kahler
