BQ24090: CHG/ pin status during high temperture >45 degree

Part Number: BQ24090

hi,

From table 1 listed in Bq24090, at first pluging in adapter, if battery is not full charged, CHG/ pin will be always kept low even battery temperature is higher than 45 celsius degree. is it right?

Hi Ken

This behavior sound correct and is true for other devices. Will double check in the lab and update you later today.
