NPS4053GVH 5.5 V Load Switch with Adjustable Current Limit

ElecSuppliers Part Number GuideAug 21, 2026

NPS4053GVH is a power management load switch from Nexperia, designed for applications that require controlled power distribution, current limiting and protection. It belongs to the NPS4053 family and is designed for load voltages from 2.5 V to 5.5 V.

The device combines a high-side power switch with adjustable current limiting, over-temperature protection, reverse voltage protection and soft-start functionality. These features make NPS4053GVH suitable for USB power paths, portable electronics, computing equipment and other low-voltage power management applications.

NPS4053GVH Key Features

NPS4053GVH has a typical on-resistance of 55 mΩ at a 5.5 V input, 65 mΩ at 3.6 V and 80 mΩ at 2.5 V. The maximum continuous current is specified at 2 A, while the adjustable current-limit range extends from 110 mA to 2.5 A. At a 1.2 A current-limit setting, the specified current-limit accuracy is ±6%.

The adjustable current-limit function allows designers to select an appropriate protection threshold for the connected load. When the load current exceeds the programmed limit or a short circuit occurs, the device enters constant-current limiting rather than simply allowing the current to increase uncontrolled.

NPS4053 also integrates active reverse-voltage protection. When the switch is disabled, there is no body-diode current path from OUT to IN, helping prevent unwanted reverse current through the power path. Built-in soft start controls the output voltage transition and helps reduce inrush current and voltage surges during startup.

NPS4053GVH Package and Operating Range

The NPS4053GVH is supplied in the SOT457 package, also identified as TSOP6 or SC-74. The package uses six pins and is intended for compact surface-mount designs where board space is limited. DigiKey identifies NPS4053GVH as a high-side power switch with one output and a 6-TSOP supplier package.

The operating temperature range is specified from -40 °C to +125 °C. The input/load voltage range is 2.5 V to 5.5 V, making the device suitable for common 3.3 V and 5 V power rails.

Nexperia lists NPS4053GVH under the NPS4053 family alongside other package and qualification variants. The NPS4053 family is positioned as a 5.5 V load-switch solution with precision adjustable current limiting.

Applications for NPS4053GVH

NPS4053GVH can be used where a low-voltage power rail needs controlled switching and protection. Typical applications include USB ports and hubs, laptops, docking stations, desktop systems, set-top boxes, HDTV equipment and optical socket protection. It can also be used in dedicated current-limiting circuits.

For USB power applications, the NPS4053 datasheet recommends using at least 120 µF of output capacitance. Other applications should select the output capacitor according to the required transient response and system design conditions.

NPS4053GVH for Power Distribution Designs

A conventional power switch may require additional external circuitry to provide current limiting and fault protection. NPS4053GVH integrates several of these functions into a compact six-pin device, helping simplify the power distribution section of a circuit.

The low on-resistance helps reduce conduction losses during normal operation, while the adjustable current limit allows the protection threshold to be matched to the connected load. The combination of current limiting, over-temperature protection, reverse voltage protection and soft start makes NPS4053GVH useful in compact power-management designs.

For engineers evaluating NPS4053GVH, important parameters to check include input voltage, normal load current, required current-limit threshold, PCB thermal conditions, output capacitance and package requirements. These factors should be evaluated together rather than selecting the device only according to its maximum current rating.

NPS4053GVH Availability and Replacement Considerations

NPS4053GVH is the Nexperia ordering variant associated with the NPS4053GV device in the SOT457 package. Nexperia's product information identifies NPS4053GVH as an ordering part number for the NPS4053 family.

When sourcing NPS4053GVH, buyers should verify the exact manufacturer part number, package, electrical specifications and current supply status before placing an order. Distributor inventory can change over time, and a compatible alternative should be evaluated against the original circuit requirements rather than selected only by package or nominal voltage.

For designs currently using NPS4053GVH, the most important replacement parameters are the 2.5 V to 5.5 V operating range, low on-resistance, adjustable current-limit capability, high-side switching configuration, protection functions and SOT457 package.

NPS4053GVH is therefore a practical option for compact 2.5 V to 5.5 V power distribution designs where controlled load switching and adjustable overcurrent protection are required.
