Other Parts Discussed in Thread: BQ24650

Hi,

we are looking for a Solar power supply based Lead acid battery charger, it should able to handle 60A current max, and input voltage range from 6V-24V and adjustable output (3V-12V) at 3A and ably power both the load and Battery simiultaneously.Need your thoughts for the Right Charging Mechanism and available development boards.

    Hi Ayla,

    The closest fit is the BQ24650 modified as explained in the app note below.  The charger cannot driver FETs to 60A unless FET gate driver circuits are added. 

     I also recommend reviewing the app note below to prevent leakage during shading

     Regards,

    Jeff
