    Hi Saravanan,

    I assume 12V is the input source? What is the battery capacity and/or charging current?

    Regards,

    Also, do you have host I2C control or do you need resistor only configurable charger?  Our newest family is the BQ25600 family.  The B25606 is the non-I2C version.

    Saravanan,

    If you have a > 12V input source, I recommend the standalone BQ24610 controller with external FETs or BQ24171/2 with internal FETs.  Both are standalone.  

    If your source could drop below 12V, then I recommend BQ25713 which requires host control through I2C.

    Regards,

    Dear Jeff,

                 Thanks. We have exactly 12V input source so  BQ24610 is OK?

    Hi Saravanan,

    The BQ24610 is a buck only charger and needs some headroom (~0.5V) above the final battery regulation voltage for fast charging.  If your input source is not higher than your battery then you must use a boosting or buck and boosting charger like BQ25713.

    Jeff
