... Charge Qualification and Preconditioning Upon insertion of a battery or application of an external supply, the MCP73827 verifies the state of the SHDN pin. The SHDN pin must be above the logic High level. If the SHDN pin is above the logic High level, the MCP73827 initiates a charge cycle. The charge status ...

... The preconditioning current is scaled to approximately 43 PEAK 5.1.5 SUPPLY VOLTAGE ( The V input is the input supply to the MCP73827. The IN MCP73827 automatically enters a power-down mode if the voltage on the V input falls below the voltage on IN the V pin. This feature prevents draining the battery BAT pack when the V supply is not present ...
