While in DPPM mode, if the charging current falls to zero and the system load current increases beyond the programmed input current limit, the voltage at PMID reduces further. When the PMID voltage drops below the battery voltage by VBSUP1, the battery supplements the system load. The battery stops supplementing the system load when the voltage on the PMID pin rises above the battery voltage by VBSUP2. During supplement mode, the battery supplement current is not regulated, however, the Battery Over-Current Protection mechanism is active. Battery charge termination is disabled while in supplement mode.
