INA241A: application question

Part Number: INA241A
Other Parts Discussed in Thread: INA241B

Tool/software:

Hi experts! I'm Yoyo.

My customer Delta is working on a hot swap circuit

They're using an MCU STM32G474MC to replace our INA241A

They think the circuit design could be a lot easier.

How can I persuade them to use  INA241A

What's the advantage of using our INA241A than directly use a  STM32G474MC instead.

    Hello Yoyo,

    I need more detail on what they are doing and why the INA241A was used for.  The biggest benefit of the INA241A is the accuracy, high input common mode, Enhanced PWM rejection, and speed.  They can go to the INA241B if lower accuracy is required.  Also a current sense amplifier give the ability to lower your Rshunt reducing the power.

    What value is the INA241A giving from the above?  How would they change the implementation?

    Regards,

    Javier
