Other Parts Discussed in Thread: BQ76200, , BQ78350-R1

Hi Sir,

I have a problem with the design(BQ76940+BQ78350-R1+BQ76200) which always read the incorrect TS1 value(-273.2degreecC) even use fixed 10Kohm R and calibration.

Is there any problem with the below circuit design? or any possible reason?

Hi David,

Thanks a lot for your reply.

I have found the reason for this invalid temperature of TS1 is because of the setting of the temperature.

It's all solved and sorry to make you inconvenience.

Best regards,

James
