Hi team,
Customer wants to use BQ40Z50-R2 for 3S3P battery pack. Is BQ40Z50-R2 able to measure 10 temp points (1 temp per cell + discharge/charge FET)?
Does using MUX or TMP468 (remote temp sensor) work?
Regards,
Hayashi
Hi Hayashi,
The bq40z50 has 4 available temperature sense pins, however I do not believe these should be MUX'd. Large changes in the temperature from switching between thermistors can effect the gauging performance of the device.

Hi Anthony,
How about TMP468 (remote temp sensor) solution? Have aware of this IC?

Hi Hayashi,
The bq40z50-R5 has the functionality to be used with the TMP468 for temperature sensing seen below:
