Product details
Overview
NX5P2190UKZ from NXP Semiconductors is a logic-controlled high-side power switch designed for USB OTG VBUS domain isolation and protection. It features adjustable current limiting (200–2000 mA), 100 mΩ max RON at 4.0 V, 30 V VBUS tolerance, and integrated UVLO/OVLO/OTP/OCP/RCP protection circuits. Its 1.8 V-compatible EN input enables direct interfacing with low-voltage controllers in portable battery-powered systems.
For engineers reviewing the NX5P2190UKZ datasheet, NX5P2190UKZ pinout, NX5P2190UKZ application, or NX5P2190UKZ equivalent, key selection considerations include its WLCSP9 package footprint, open-drain FAULT signaling, analog VDET voltage monitoring, soft-start in-rush control, and low-power mode (20 µA IGND) with retained UVLO functionality.
Technical Context
The NX5P2190UKZ implements a single N-channel MOSFET high-side switch with programmable over-current threshold via external RILIM (20–300 kΩ), enabling precise in-rush and steady-state current limiting. Its protection architecture operates autonomously: UVLO activates below 3.2 V, OVLO above 5.9 V, OTP at 125 °C, and RCP when VBUS exceeds VINT by >30 mV for >4 ms or >450 mV.
Control logic includes active-HIGH EN with integrated level translation (1.8 V compatible), open-drain FAULT output indicating any fault condition, and analog VDET output scaling linearly with VBUS (1.5–5.5 V range). The device supports dynamic switching with typical enable time of 0.24 ms and turn-off time of 34.5 ms under recommended conditions.
Key Specifications

| EN (C1) | Enable control input | Active-HIGH logic input with 1.8 V compatibility; forces low-power mode when LOW |
| ILIM (C3) | Current limit programming terminal | Analog input/output setting OCP threshold via external resistor (20–300 kΩ) |
| VDET (A2) | Analog voltage monitor output | Linear analog output (1.5–5.5 V) tracking VBUS for real-time host supervision |
| FAULT (B2) | Fault status indicator | Open-drain output pulled LOW during any fault (UVLO/OVLO/OTP/OCP/RCP) |
| GND (C2) | Reference ground | 0 V reference for all voltages and protection thresholds; requires solid PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable current limiting | 200–2000 mA set by external RILIM, enabling precise in-rush and overload control |
| Reverse bias protection | Detects VBUS > VINT + 30 mV for >4 ms or >450 mV, preventing back-drive into source |
| Soft-start slew rate control | Clamps in-rush current until VBUS reaches VINT − 200 mV, reducing peak stress on source |
| Low-power mode retention | Maintains UVLO monitoring while disabling all other protections and reducing IGND to 20 µA |
| ESD robustness | HBM >2 kV; IEC61000-4-2 contact discharge >8 kV on VBUS - meets USB system-level ESD requirements |
Applications
| USB OTG Host Power Management | Portable Device VBUS Isolation |
|---|---|
Use Scenario: A smartphone acts as USB OTG host, supplying 5 V power to peripherals like keyboards or flash drives via micro-AB port. IC Role / Device Role / Timing Role: High-side power switch controlling VBUS delivery with real-time current and voltage monitoring. Use Value: Prevents back-feed from peripheral into phone battery, enforces safe in-rush limits, and signals faults to OS before damage occurs. |

IC Role / Device Role / Timing Role: Fault-aware power domain isolator between battery regulator and USB interface. Use Value: Guarantees no reverse current flow during cable swap events and disables VBUS within 2 µs of over-current detection. |
| USB-C Accessory Detection | Industrial USB Hub Protection |
Use Scenario: A USB-C audio dongle detects whether it's connected to a host or peripheral and configures power path accordingly. IC Role / Device Role / Timing Role: Smart VBUS switch with analog VDET feedback enabling host/peripheral role negotiation. Use Value: Enables accurate VBUS presence sensing without ADC overhead; FAULT pin triggers firmware reconfiguration on disconnect. |
Use Scenario: An industrial USB hub powers multiple field devices; must survive load dumps, hot-plug transients, and short circuits. IC Role / Device Role / Timing Role: Primary over-current and over-voltage protector on each downstream port. Use Value: Limits fault propagation across ports; 30 V VBUS tolerance absorbs ±15 V common-mode noise on factory floor cabling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCK127G | Lower RON (40 mΩ typ), but fixed 1.5 A current limit; no VDET output or RCP | Lacks analog VBUS monitoring and reverse-bias protection - unsuitable for USB OTG role negotiation | Choose TCK127G only if fixed current limit and minimal BOM count outweigh need for VDET and RCP. |
| TPS22919 | Wider supply range (0.75–5.5 V), but no OVLO/UVLO hysteresis and no VDET output | Missing VDET and lacks dedicated reverse-bias detection - requires external comparator for VBUS supervision | Select TPS22919 when ultra-low VIN operation (<3 V) is required and VBUS monitoring is handled externally. |
Compared with TCK127G and TPS22919, the NX5P2190UKZ uniquely integrates VDET analog monitoring, programmable RCP, and coordinated UVLO/OVLO hysteresis-making it the only option among the three that satisfies full USB OTG specification compliance without external components.

FAQ
What is the maximum continuous current rating for the NX5P2190UKZ?
The NX5P2190UKZ supports up to 2 A continuous switch current (ISW) at ambient temperatures up to +85 °C. This rating assumes proper PCB thermal design per NXP's recommended layout guidelines, including multi-layer copper pours to minimize Rth(j-a). Exceeding this current may trigger over-current protection or thermal shutdown depending on duty cycle and heatsinking.
How does the NX5P2190UKZ implement reverse bias protection?
The NX5P2190UKZ detects reverse bias when VBUS exceeds VINT by more than 30 mV for longer than 4 ms, or by more than 450 mV at any time. Upon detection, it disables the internal N-channel MOSFET within microseconds and pulls the FAULT pin LOW. This prevents back-driving current from a powered peripheral into the host's power rail, protecting both the switch and upstream regulator.
Can the NX5P2190UKZ operate with a 1.8 V microcontroller GPIO driving the EN pin?
Yes - the NX5P2190UKZ includes integrated logic-level translation on the EN pin, allowing direct connection to 1.8 V GPIOs without external level shifters. Its VIH threshold is 1.2 V min and VIL is 0.4 V max at −40 °C to +85 °C, ensuring reliable activation and deactivation across temperature and voltage tolerances.
What is the function of the VDET pin on the NX5P2190UKZ?
The VDET pin on the NX5P2190UKZ provides an analog voltage output (1.5–5.5 V) directly proportional to the VBUS voltage, enabling host MCUs to monitor VBUS level without external resistive dividers. It supports real-time detection of VBUS presence, brown-out, or overvoltage conditions, and is used in USB OTG role negotiation and dynamic power budgeting.
Does the NX5P2190UKZ require an external pull-up resistor on the FAULT pin?
Yes - the FAULT pin is an open-drain output and requires an external pull-up resistor to a valid logic-high voltage (typically VINT or another system rail). NXP recommends a pull-up resistance between 20 kΩ and 200 kΩ. Without this resistor, the FAULT signal cannot transition HIGH to indicate fault clearance, compromising system-level fault recovery.
