17) Latch except when Vbb -VOUT < VON(SC) after shutdown. In most cases VOUT = 0 V after shutdown (VOUT ≠
0 V only if forced externally). So the device remains latched unless Vbb < VON(SC) (see page 4). No latch
between turn on and td(SC).
18) With latch function. Reseted by a) Input low, b) Undervoltage
19) No auto restart after overvoltage in case of short circuit
20) Low resistance short Vbb to output may be detected in ON-state by the no-load-detection
