BQ25601: Ishort current and Pre-charge current under low temperture(T1-T2)

Part Number: BQ25601

Hi Team,

Customer get one question about the BQ25601 Ishort current and Pre-charge current under low temperture(T1-T2). As it mentioned, the charge current would be reduced to half of 1/5 current. Does this works both for Ishort, Pre-charge current, and normal charge current?

Anohter quesion is, if the normal charge current is set to 120mA, and set the ISET bit to 1; does the charge current down to 120mA/5=24mA? If not, what's the value?

Thanks and Best Regards,

Will

    Wil,

    In Cool condition, precharge current and fast charge current will be reduced according to ISET setting. Ibatshort does not change with TS temperature.

    If the normal charge current is set to 120mA, and set the ISET bit to 1, the charge current goes down to 120mA/5=24mA.

    Thanks,

    Ning.
