In output short conditions, the LT8350S can be set to hiccup, latch-off, or keep-running fault protection mode with a

resistor between the SS and VREF pins. Without any resistor, the LT8350S will hiccup between 0.2V and 1.75V and go

around the UP/RUN, OK/RUN, FAULT/RUN, and DOWN/STOP states until the fault condition is cleared. With a 499kΩ

resistor, the LT8350S will latch off until the EN/UVLO is toggled. With a 100kΩ resistor, the LT8350S will keep running

regardless of the fault.
