stmps2242, stmps2252, stmps2262, st mps2272 functional description doc id 15050 rev 2 7/18 3 functional description 3.1 fault blanking the stmps devices feature a 10 ms fault blanking. fault blanking allows current-limit faults, including momentary short-circuit faults that occur when hot-swapping a capacitive load, and also ensures that no fault is issued during power-up. when a load transient causes the device to enter current limit, an internal counter starts. if the load fault persists beyond the 10 ms fault-blanking timeout, the fault output asserts ?low?. load-transient faults less than 10 ms (typ.) do not cause a fault output assertion. only current-limit faults are blanked. die over-temperature faults and input voltage drops below the uvlo threshold cause an immediate fault output. 3.2 overcurrent/over-temperature protection in overcurrent or short-circuit condition, the switch limits the current at 500 ma for stmps2242/stmps2252 and 1000 ma for stmps2262/stmps2272. if temperature of die goes above limit value, the switch turns off. 3.3 reversed current blocking when the switch is off, or when the stmps device is un-powered (v cc =0 v), the switch behaves as an hi-z at the output pin, ensuring that no reverse current will flow into the device when vi maximum rating stmps2242, st mps2252, stmps2262, stmps2272 8/18 doc id 15050 rev 2 4 maximum rating stressing the device above the rating listed in the ?absolute maximum ratings? table may cause permanent damage to the device. these are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. exposure to absolute maximum rating conditions for extended periods may affect device reliability. 4.1 absolute maximum rating 4.2 recommended operating conditions table 3. absolute maximum ratings symbol parameter value unit v i input voltage range ?0.3 ? 6.0 v v o output voltage range ?0.3 ?
