BQ24072: BQ24072 vs BQ24072T

I have a quick question: what is the difference between BQ24072 and BQ24072T? I couldn’t find any and when I replaced the one without “T” suffix to the one with, the battery charging stopped working.

Thank you!

    Hi Lazar
    The Battery Pack Temp Monitor (TS Pin) for BQ24072 is current base and for BQ24072T it is voltage based. The adjustment range of the T is more flexible.

    The unit that has stopped working is probably detecting the battery temp is high or low and preventing charging.
