Sleep Mode bq78350

Hi there,

I am testing a battery made up of 12 cells, using the bq78350.

In order to meet the sleep mode requirements I have set the sleep parameters following the section 7.3.1 of the manual, using these parameters and values:

BLT0= 1;

BLT1=0;

Sleep Current =100 mA:

Voltage Time= 5 seconds;

OperationStatus[SDM]=0;

and all the alerts are set to low.

I decided to set the sleep current to 100 mA, because with that value no noise will wake up the TI chip.

When I stop charging or discharging, the current sensor reports 0 mA, but I cannot see any change of the SLEEPM bit or the SLEEP bit of the Operation Status in my window panel. That's why I do not know if the system is actually in sleep mode or not.

Is there any way to confirm that the bq78350 is in sleep mode?

Regards,

Oscar.
