Part Number: BQ24075

Hi,

I need to calculate RCOLD value at tcold =0 degree celsius.

Available input which i have is B= 3435. NTC AT 25 degree celcius is 10KOhms

We have set THOT = 60  degree celsius. We got RHOT as 2.980kOhms.

Please send me RCOLD value or some equtaions.

Thanks in advance

    Hello Rahul,
    The low temperature trip point (Vcold) is 2.1V. The bias current on the TS pin is 75uA. This means that the Rcold should be 28k ohms. This is around 0 degrees Celsius looking at the 103AT datasheet.
    Regards,
