Hello,
I am trying to make use of the BQ24090 as part of a battery pack. I have the chip set up as shown in the attached diagram. J3 is connected to the battery and U11 is not currently connected. When I apply a 5v supply to this…
Part Number: BQ24091 Other Parts Discussed in Thread: BQ24090
Hi, TI expert.
According to the BQ24091 datasheet, I understood that using ß=3370 out of 100K NTC would allow setting from 0 to 45°C without additional external resistors.
However…
