Latch-off mode is active when the DELAY pin connects to GND through a capacitor. When a current limit is reached, the output current holds at the setting current, but latches off after a preset DELAY time (tdl1+ tdl2). tdl1 is the default delay time, and tdl2 is a configurable delay time set by a capacitor. Regardless of whether the current limit is removed or not, the output remains latched off. The output only recovers when IN is toggling.
tdl2 can be calculated by Equation 2.
