When LED+ is shorted to GND, V_FB is low and V_COMP is driven high and clamped. The high-side MOSFET is forced to turn on with maximum PWM duty cycle, after either the high-side or low-side overcurrent limit is triggered, the device starts the auto-retry counter. When the counter t_{RETRY_ON} expires, the device shuts down and starts another counter t_{RETRY_OFF}. During the shutdown period, both high-side and low-side NMOSs are switched off. The device repeats these actions until the failure condition is removed.
