Auto-retry mode is active when the DELAY pin is externally pulled up. The pullup voltage must be higher than V_dl(th). When the current limit is reached, the output current holds at the setting current, but periodically turns on for t_hic(on) and turns off for t_hic(off). The device checks the current limit status at the falling edge of t_hic(on) clock. If current limit status is captured, the device shuts down for t_hic(off). If the current limit status is not captured because of the off window during the thermal conditions, the device keeps turning on for additional t_hic(on) or more until the current limit status is captured.
