Hi~ Ti support teams
Our project use BQ25883 as a charger IC for battery.
We want to use the TS ADC function, as we know the BQ25883 can detect the TS NTC as ADC pin.
Then we can know the NTC tempeture in percentage.
We use an application to monitor the TS ADC 0 and TS ADC 1 Register and output the temperature in percentage each second.
We put the system in a temperature chamber to check the result.
We found the value that we read from the register is drastically.
We don't know the reason~ Why it will change so many degree within 1 sec?
