... The switch remains on after the overload condition disappears. The MAX4785 and MAX4787 are available in a tiny space-saving 4-pin or 5-pin SC70 package. The MAX4786 and MAX4788 are available only in the 4-pin SC70 package. For higher current current-limiting switches, refer to the MAX4789–MAX4794 and MAX1693 data sheets. ...

... When the load current exceeds the preset current limit for greater than the fault-blanking time, the switch opens. The MAX4786 and MAX4788 have an autoretry function that turns on the switch again after an internal retry time expires. If the faulty load condition is still present after the blanking time, the switch turns off again and the cycle is repeated ...
