Part Number: BQ25606
Other Parts Discussed in Thread: BQ25616

Hi Sir,

My customer would like design BQ25606 and the end-customer request to output current under different temperature.

0 ºC ~10ºC is 0.2C，

10 ºC ~45 ºC is 1C

Is that right to tune RT1 and RT2 value to meet this requirement?

SHH,

RT1 and RT2 are determined by T1 and T5, T2 and T3 are dependent on RT1 and RT2. For RT1 and RT2 calculation tool, please refer to http://www.ti.com/lit/zip/slurax7. Although it was developed for the BQ2589x, the principle is similar and can be used for BQ25606 with a few changes.

At cool temperature (T1-T2), the charge current is reduced to 20% of programmed fast charge current automatically.

Thanks,

Ning.
