    Hi Star,

    According to your design, why you parallel two 0.1ohm resistor? We recommend you use only one sense resistor to get rid of any risk in current sensing.

    Could you double check with scope to plot IBAT, VBAT, STAT1 and OUT? We need to check if it really terminate charging.

    Thanks,
