NPS4053-Q100
5.5 V, 55 mOhm load switch with precision adjustable current limit
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. An internal voltage comparator disables the load switch when the output voltage is higher than the input to protect devices on the input side of the switch. The FLG pin is an active low output to indicate overcurrent, over temperature and reverse voltage conditions.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
