Notes:
5) Min. VIN is determined by internal UVLO and relative to BATT voltage
6) High Charge current make MP2607 get into thermal fold-back and charge current will drop down.
7) ICHG0 is the target preprogrammed charge current (Die temperature below 110°C), i.e. typical value of ICHG.
8) IEOC0 is the target preprogrammed battery full current threshold, i.e. typical value of IEOC.
