Other Parts Discussed in Thread: BQ24650

Hello dear desingers. 

i wonder that does anybody use Typical System Schematic in the datasheet of bq24650. I'm planing to create a circuit which contain this circuit too . 

I can hear that ti already made it. But i want to hear from customers.

Have a good day.

    I would like to suggest that you use the bq24650 EVM for your design. The typical application circuit in the datasheet provides the basic functionality.  The EVM design includes additional components for noice reduction and circuit protection that you are likely to need in your actual design.  If not needed, you can leave them unpopulated.  The EVM has been built and tested and performes very well.  You will be able to modify it to meet your specific needs.

    Hello,

    I planning to use EVM design, but i want to use it in a such a way that i can charge different battery capacities.

    I am planning to replace the sensing resistor with variable resistance, which can be adjusted based on the battery capacity.

    Please share your thoughts using this method, and let me know if there is better approach.

    Thanks

    Hi Hisham,

    Using switches or jumpers to add/remove sense resistors in series/parallel may be a solution, but the problem is that it will add more resistance and unpredictable values for it to be effective. If accuracy is not your concern, you may find this as a solution.

    If you find a potentiometer/variable resistor in the milli-ohm range that works for you, make sure that it can handle the power you are sending through it.

    The other possibility is to manually change the resistor for each capacity.

    Thanks,
    Steven
