BQ76940: BQ76940

Part Number: BQ76940

Hi Ti Team,

I am using the BQ7694003DBT BMS IC for battery managment with stm32 microcontroller. I am using the "sluc583" source code.I am reading the cell  voltages,pack voltages which is appearing ok.

Then i am reading the  external thermistor(ntc 10kohm) temperature from BQ7694003DBT. Sometimes Temperature is appearing ok(for example 22 degree celcius). But sometime when we read the temperature after initialization(power on the microcontroller), -273 degree celcius temperature is appear. i don't know why sometime, it is showing wrong temperature.Please help me to resolve this issue.

When i again flash(power on) the microcontroller 2 to 3 times then thermistor temperature is appearing ok. Wrong temperature is only appear sometimes when controller is reprogram/flash.

Note:- After initialization or power up the microcontroller, if thermistor temperature is appearing ok(22 degree celcius) then it does not show -273 degree celcius in meantime .

This wrong temperature appear only when we power on the microcontroller. 

Thanks with regards
