NPS4053-Q100 Overview
Description
The NPS4053-Q100 is a 5.5 V, 55 mΩ load switch with precision adjustable current limit from 110 mA to 2.5 A. The NPS4053-Q100 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.
