... When the load current exceeds the preset current limit for greater than the fault-blanking time, the switch opens and FLAG asserts. The MAX4915A/MAX4917A 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 ...

... A thermal fault and input voltage drops below the UVLO threshold cause FLAG to assert immediately and not wait for the blanking time. The MAX4914B/MAX4915A/B/MAX4917A/B have a ther- mal-shutdown feature to protect the devices from over- heating. The switch turns off and FLAG goes low immediately (no fault blanking) when the junction temper- ature exceeds +150° ...
