Hi, my name is Pattama. From my last question about my BQ76920 doesn't wake and I had got a solution that can solve my problem. Last Forum
But, when I try to use REGOUT pin to power my controller I found this pin is 0 volt! Moreover, I face the same problem again!
I do the schematic as below.
I measure the voltage at each pin thus,
SDA,SCL = 5 V
TS1=3.2 V (Equal to battery cell voltage)
REQOUT,DSG,CHG = 0V
I wonder that my BQ76920 may got the damage? Or I do something wrong.
Is REGOUT has 0 V normal?
Hi Pattama,
It seems you posted the same question twice. It is also in this thread: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1032130/bq76920-my-bq76920-can-t-do-a-communication-to-a-host-controller-and-regout-doesn-t-work
I will close this thread and answer the other one.
Regards,
Matt
