NPS4053 - nexperia

NPS4053 load switch

The NPS4053 is a 5.5 V, 55 mΩ load switch with precision adjustable current limit from 110 mA to 2.5 A. The NPS4053 switch limits the output current to a constant current by using a constant-current mode when the output load exceeds the current limit threshold or shorted. An internal voltage comparator disables the load switch when the output voltage is high.
