    Hi Kevin,

    What is the desired charge current?  

    Does a system load need to be powered by the input source?  If so, what is the system load?

    Is a host processor available to provide I2C control or does the charger need to be standalone?

    Can you explain more about "power indicator to indicate external input and current power"?

    Regards,

    Jeff
