Nexperia USA Inc. NPS4001GVH

Overview

NPS4001GVH from Nexperia is a P-channel 5.5 V load switch with 55 mΩ typical R_DS(on) at 5.5 V, 2 A rated current, and integrated constant-current limiting, reverse-voltage protection, and thermal shutdown. It serves as a protected power-path controller in USB ports, docking stations, and set-top boxes, enabling safe hot-swap and fault-isolated rail switching.

For engineers reviewing the NPS4001GVH datasheet, NPS4001GVH pinout, NPS4001GVH application, or NPS4001GVH equivalent, key selection criteria include its 75 mV reverse-voltage trip threshold, 8.5 ms overcurrent deglitch time, active-low FLG flag behavior, and SOT753 (SC-74A) 5-pin package compatibility with space-constrained USB and consumer electronics designs.

Technical Context

The NPS4001GVH implements a P-MOSFET-based load switch with internal current-sense amplifier and comparator driving a TRCB (thermal-reduction control block) to enforce 2.37 A typical current limit during overload or short-circuit events. Its reverse-voltage protection activates when V_OUT exceeds V_IN by ≥75 mV for ≥0.5 µs, turning off the MOSFET within that timeframe.

It integrates undervoltage lockout (2.35 V turn-on threshold with 25 mV hysteresis), soft-start via controlled slew rate (0.2–1 ms rise/fall times), and a 300 Ω internal output discharge path. The FLG pin is an open-drain N-MOS output with deglitch filtering (0.2 ms for reverse voltage, 8.5 ms for overcurrent) and immediate assertion for overtemperature (>155 °C).

FAQ

What is the minimum input voltage required to enable the NPS4001GVH?

The NPS4001GVH features an undervoltage lockout (UVLO) circuit with a 2.35 V turn-on threshold and 25 mV hysteresis. Below 2.35 V, the device remains disabled regardless of ON pin state. This ensures stable operation only when the input rail is sufficiently regulated, preventing erratic switching during brown-out conditions.

How does the FLG pin behave during simultaneous overcurrent and overtemperature events?

The FLG pin asserts low immediately upon overtemperature detection (>155 °C) and after 8.5 ms for overcurrent. During simultaneous faults, FLG goes low at the earlier of the two triggers - typically overtemperature - and remains asserted until both conditions clear and the deglitch timers expire. No priority masking or latching is implemented.

Can the NPS4001GVH be used without an external pull-up on the FLG pin?

Yes - the FLG pin may be left floating or shorted to GND if fault monitoring is unused. When floating, the open-drain output remains high-impedance; when shorted to GND, it pulls low continuously. Neither configuration damages the device, but diagnostic capability is forfeited in both cases.

Is the 120 µF output capacitor mandatory for all applications?

No - the 120 µF minimum applies only to USB port applications per USB specification inrush and droop requirements. For non-USB uses (e.g., set-top box subsystems), output capacitance should be selected based on actual transient load step magnitude and acceptable voltage sag, typically ranging from 10 µF to 100 µF depending on load dynamics.
