DRV8245-Q1: What is the current sense accuracy across the current range 1A to 11A?

DRV8245-Q1:IPROPI current sensing temperature characteristics

Part Number: DRV8245-Q1

Hello
My name is Shoko Kitazawa.


I would like to use the IPROPI current sensing function of DRV8245S-Q1.


I would like data on temperature drift when using this current sensing.


This is because if the temperature drift is small, even if there is a 50% deviation in the current value up to 0.2A<Iout<0.5A,

it can be corrected by the microcontroller.


thank you.

    Hey Kitazawa-san,

    Unfortunately we don't have detailed data on the temperature drift, I only have data for device min/room/max temperatures and I can't share that publicly.  I recommend you test it out yourself with a resistive load and run your own characterization on it, this will give you better data than I have for characterizing it. 

    Regards,
