NPS4053
5.5 V, 55 mOhm load switch with precision adjustable current limit
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 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.
Features and benefits
Input operating voltage range (VIN): 2.5 V to 5.5 V
Maximum continuous current (IMAX): 2 A
ON resistance (RDS(on)):
VIN = 5.5 V: 55 mΩ (typical)
VIN = 3.6 V: 65 mΩ (typical)
VIN = 2.5 V: 80 mΩ (typical)
Adjustable current limit: 110 mA to 2.5 A
±6 % current limit accuracy at 1.2 A
ILIM pin protection: can be shorted to ground or left floating
Constant current during current limit
No body diode when disabled (no current path from pin OUT to pin IN)
Active reverse voltage protection
Built in soft start
UL 62368 recognition
