    Hi Jingguo

    The Top-Off Timer will extend the Taper-Charge phase (CV).  Solutions with low termination currents ( 50mA to 100mA ) will benefit for this feature.

    Typically the termination point is 10% of fast charge current and this feature will provide additional charge based on setting of REG07
