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.

特性

  • 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

  • SOT457 (TSOP6) and SOT8044-1 (HWSON6) package option

  • 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

    • IEC 61000-4-2 air-gap discharge 15000 V

  • Specified from -40 °C to +125 °C

目标应用

  • USB ports/hubs, laptops, docking station and desktops

  • Set top box

  • HDTV

  • Optical socket protection

  • Current limiting circuits

Note: Connect at least 120 µF capacitor at output for USB port application, other applications except USB choose output capacitor according to actual transient requirements.
