Nexperia USA Inc. NPS4069GVH

Overview

NPS4069GVH from Nexperia is a 5.5 V, P-channel load switch with 55 mΩ typical R_DS(on) at 5.5 V, 1.5 A rated current, and integrated constant-current limiting, active reverse-voltage protection, and thermal shutdown. It operates across -40 °C to +125 °C and is used in USB port power management, set-top boxes, and HDTV power rails where controlled inrush and fault isolation are critical.

For engineers reviewing the NPS4069GVH datasheet, NPS4069GVH pinout, NPS4069GVH application, or NPS4069GVH equivalent, key selection criteria include its 75 mV reverse-voltage trip threshold, 8.5 ms overcurrent deglitch time, FLG open-drain fault reporting, soft-start timing, and SOT753 (SC-74A) package compatibility with space-constrained PCB layouts.

Technical Context

The NPS4069GVH implements a P-channel MOSFET-based load switch with internal current-sense amplifier and TRCB (thermal regulation and current block) control logic. Its constant-current mode activates when load exceeds 1.28–2.46 A, limiting output to ILIMIT without latch-off unless thermal shutdown intervenes.

Reverse-voltage protection uses a dedicated comparator that disables the MOSFET within 0.5 µs if V_OUT exceeds V_IN by ≥75 mV. The FLG pin provides consolidated open-drain fault signaling for overcurrent (8.5 ms deglitched), overtemperature (immediate assertion), and reverse voltage (0.2 ms deglitched).

Key Specifications

Pinout & Package

SOT753 (SC-74A / TSOP5) - 5-lead plastic surface-mount package, 1.3 mm × 2.5 mm footprint, 1.1 mm max height, optimized for high-density USB and consumer electronics PCBs.

FAQ

What is the maximum continuous output current supported by the NPS4069GVH?

The NPS4069GVH supports 1.5 A continuous output current under recommended operating conditions (T_amb ≤ +125 °C, proper PCB thermal design). Its current-limit threshold is specified from 1.28 A to 2.46 A, with typical activation at ~1.83 A. Derating is required above +85 °C ambient due to thermal resistance (R_θJA = 160 °C/W) and junction temperature limits (155 °C shutdown).

Does the NPS4069GVH require an external pull-up resistor on the FLG pin?

Yes - the FLG pin is an open-drain N-MOS output and requires an external pull-up resistor (typically 10–100 kΩ) to VIN or another compatible rail. Without it, the FLG signal cannot assert HIGH after fault clearance. The datasheet specifies I_FLG sink capability up to 10 mA, and VOL is guaranteed ≤180 mV at 1 mA sink current.

Can the NPS4069GVH be used in automotive applications?

No - the NPS4069GVH is not AEC-Q200 qualified and lacks automotive-specific validation. While its operating temperature range (-40 °C to +125 °C) overlaps with some automotive ambient requirements, Nexperia explicitly states non-automotive qualification in its legal disclaimers. It is intended for consumer, computing, and industrial equipment only.

How does the NPS4069GVH handle output short-circuit events?

Upon output short-to-ground, the NPS4069GVH immediately enters constant-current mode, limiting I_OUT to the ILIMIT threshold (~1.83 A typ). It sustains this condition until the short is removed or thermal shutdown triggers at 155 °C. FLG asserts low after 8.5 ms deglitch delay. No latch-off occurs - the device auto-recovers once fault clears and thermal conditions normalize.
