    Allen,

    Would you please share more information about this? From what-to-what value OCP decreases a high temp? What high temperatures was the device tested? Could you please share schematic of the test setup? How many devices have you tested? Did you find the same issue on all the tested devices or just some of them?

    That information will help for better debugging

    Thank you
