Part Number:BQ76940EVM
Hello Everyone,
I am using BQ76940EVM and Bqstudio. Gas gauge bq78350 was also working well but when i changed dc power source smps to 14s battery pack (55.8V), bqstudio showed connection lost warning. I was using resistor divider switch S3 and S4 for cell input and AFE cell map was 14S (5fff) in both the cases. I have checked voltage at TP1 while pressing the boot switch S1, it shows around 1.67V but device is not booting up and REGOUT shows 0V. Is bq76940 damaged? Should i replace the bq76940 ic ? Any check needs to perform to identify real problem?
Thanks in advance.
PS: I received this BQ76940EVM today only :(
