NPS4053GV

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

  • 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

Applications

  • 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.

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
