BQ25890: BQ25890 REG12 read the current incorrect in low temp

Hi

The customer design with BQ25890, REG12 read  the current is normal in room temperature.

But in 5°C, the actual charging current is 200mA, REG12 reads 50mA; when the actual charging current is 115mA, REG12 reads 0mA.

Why the REG12 read the current incorrect in 5°C?

Thanks
