Tool/software:
hello
About the IC Low-Dropout Mode, i have some question.
two case:
① the VDIAGEN= H, The diagnosis is valid.
When I gradually reduce the input voltage, I think eventually the open circuit protection will be triggered, The fault pin will be pulled low, Will the LED be turned off when the open circuit is triggered?
②the VDIAGEN= L, The diagnosis is not valid.
When I gradually reduce the input voltage, I think eventually the open circuit protection will be triggered,Will the fault pin still be pulled low? Will the LED be turned off when the open circuit is triggered?
Can one fail all fail be achieved by connecting FAUlt pins together in this case?
③and i have another quesiton, if i use PWM control, I think the open circuit detection will be detected under the condition of PWM high level. How long can the detection time be judged as a fault?
thank you
best regards
