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.
電池是4.35V/90mAh、PMID power from VIN or VBAT,、PMID電壓4.7V、關閉watch dog
請問這樣的手法為什麼會啟動DPPM? 請補充說明什麼是battery supplement mode?
