    Hello Chintu,

    Thanks for coming to the Amplifiers Forum with your question!

    Would you please provide me some measurements and an idea of what the actual sense current should be and what the INA3221 is reporting?

    What is the 3.3V supply referenced to? GND or LED_GND?

    Sincerely,
    Peter Iliya
