NPS4001
5.5 V, 55 mOhm load switch with current limitation
The NPS4001 is a 5.5 V, 55 mΩ load switch suitable for applications up to 2 A.
The NPS4001 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
Rated current (IMAX): 2 A
ON resistance (RDS(on)):
VIN = 5.5 V: 55 m? (typical)
VIN = 3.6 V: 65 m? (typical)
VIN = 2.5 V: 80 m? (typical)
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
SOT753 (TSOP5) package
ESD protection:
HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
CDM: ANSI/ESDA/JEDEC JS-002 class C2a exceeds 500 V
IEC 61000-4-2 contact discharge 8000 V
