... 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 ...

... MCP73827 6.1 Application Circuit Design Due to the low efficiency of linear charging, the most important factors are thermal design and cost, which are a direct function of the input voltage, output current and thermal impedance between the external P-chan- nel pass transistor, Q1, and the ambient cooling air. ...

... The Fairchild NDS8434 and International Rectifier IRF7404 both satisfy these requirements. 6.1.1.3 EXTERNAL CAPACITORS The MCP73827 is stable with or without a battery load. In order to maintain good AC stability in the constant voltage mode, a minimum capacitance of 10 µF is rec- ommended to bypass the V pin to GND. This capac- ...
