Tool/software:
My purpose is to reserve the UVP pin float and still detect the LED open load and short circuit. Is it possible?
After I measured，When the UVP pin is in the float state, the Fault can still detect the LED open state, how is it done? Because the datasheet describes that when the VUVP < 1.2V for 100us, the LED open load will be detected.
I guess when the LED is open load , the Error Amplifer output high for 100us is mistaken for Switching FET open, then the Fault is pulled down.
