8.3.5 Hiccup Mode
Hiccup mode prevents excessive heating and power consumption under sustained short-circuit conditions. If an overcurrent condition is maintained, the LMS36x5-Q1 shuts off its output and waits for TW (approximately 6 ms), after which the LMS36x5-Q1 restarts operation by activating soft start.
Figure 8-6 Hiccup OperationDuring hiccup mode operation, the switch node of the LMS36x5-Q1 is high impedance after a short circuit or overcurrent persists for a short duration. Periodically, the LMS3655-Q1 attempts to restart. If the short has been removed before one of these restart attempts, the LMS36x5-Q1 operates normally.
