Product details
Overview
NX5P1100UKZ from NXP Semiconductors is a logic-controlled high-side power switch with integrated ESD protection and comprehensive fault management for USB On-The-Go (OTG) VBUS domain isolation. It features dual power terminals (VINT input, VBUS output), 1 A continuous current capability, 100 mΩ max ON resistance at 4.0 V, 30 V VBUS tolerance, and active protection against overvoltage, undervoltage, overcurrent, overtemperature, reverse bias, and in-rush events. It is deployed in portable battery-powered USB OTG host devices to safely gate power between internal supply and external connector.
For engineers reviewing the NX5P1100UKZ datasheet, NX5P1100UKZ pinout, NX5P1100UKZ application, or NX5P1100UKZ equivalent, this page delivers verified functional identity, validated WLCSP12 package mapping, confirmed 12-ball terminal assignment, exact protection thresholds (UVLO = 3.2 V, OVLO = 5.75 V, OTP = 125 °C), and real-world USB OTG system integration context - all derived from NXP's official product data sheet Rev. 1 (21 March 2014).
Technical Context
The NX5P1100UKZ implements a single N-channel MOSFET high-side switch controlled by an active-HIGH EN input with integrated 1.8 V logic-level translation. Its protection architecture includes independent analog monitoring paths: VDET provides linear VBUS voltage feedback (1.5–5.5 V output), while FAULT delivers open-drain fault signaling for UVLO, OVLO, OCP, OTP, and RCP events.
Dynamic behavior is defined by soft-start slew rate control during turn-on, programmable overcurrent threshold via external ILIM resistor (40–300 kΩ), and precise timing windows: enable time ≤ 0.18 ms, disable time ≤ 1.5 ms, and deglitch filtering of 8 ms on VINT for OCP stability. All protections remain active except UVLO when EN = LOW.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 3.0 V to 5.5 V on VINT - supports direct connection to Li-ion battery or regulated 3.3 V/5 V rails without level-shifting. |
| VBUS Tolerance | 30 V maximum - withstands USB cable hot-plug transients and accidental 12 V/24 V misconnections. |
| Continuous Current | 1 A ISW - enables full-speed USB OTG host operation including charging downstream devices. |
| ON Resistance | 100 mΩ max at 4.0 V - limits conduction loss to ≤ 100 mW at 1 A, critical for thermal management in WLCSP. |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and portable consumer environments without derating. |
| ESD Rating | IEC61000-4-2 contact discharge ≥ 8 kV on VBUS/D+/D−/ID - eliminates need for external TVS diodes in USB interface path. |
| Low-Power Mode | 20 µA typical ground current with EN = LOW - preserves battery life during host sleep states. |
Pinout & Package
Package: WLCSP12 - wafer-level chip-scale package, 1.36 × 1.66 × 0.51 mm, 0.4 mm ball pitch, backside coating included.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINT (A1, B1) | Internal supply input | Primary power rail for internal circuitry and MOSFET gate drive; triggers UVLO if < 3.2 V. |
| VBUS (A3, B3) | Switched output / VBUS node | High-side switched output connected to USB connector; tolerant to 30 V; monitored by VDET and RCP circuits. |
| EN (C1) | Enable control input | Active-HIGH logic input with 1.8 V compatible threshold; forces low-power mode when LOW (except during OTP fault). |
| ILIM (D1) | Current limit programming | Analog input/output that sets OCP trigger threshold via external resistor (40–300 kΩ); sinks 10 mA when grounded. |
| VDET (A2) | VBUS analog monitor | Linear voltage follower output (1.5–5.5 V) enabling MCU ADC-based VBUS level verification and state detection. |
| FAULT (B2) | Fault status indicator | Open-drain output pulled LOW during any active protection event (UVLO/OVLO/OCP/OTP/RCP); requires external pull-up. |
| GND (C2) | Ground reference | System 0 V return for all internal circuits and protection comparators; must be low-impedance for accurate sensing. |
| D− (D2), D+ (D3), ID (C3) | ESD-protected I/O pins | Passive ESD clamps (8 kV IEC61000-4-2) tied to USB data and ID lines; no active signal routing - purely protective. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated reverse bias protection | Automatically disables switch if VBUS exceeds VINT by >30 mV for 4 ms or >450 mV - prevents back-driving host supply from peripheral. |
| Programmable overcurrent threshold | External RILIM (40–300 kΩ) sets Itrig from ~150 mA to ~1.2 A - enables precise match to USB port current budgets. |
| Soft-start slew rate control | Controls VBUS ramp rate during turn-on to limit in-rush current - avoids triggering OCP during normal enable transitions. |
| Multi-layer protection priority handling | UVLO remains active in low-power mode; OTP overrides EN control; RCP and OCP include 4 ms and 8 ms deglitch timers to reject noise. |
| 1.8 V logic-compatible EN input | VIH = 1.2 V min, VIL = 0.4 V max - interfaces directly with modern ultra-low-voltage application processors without level shifters. |

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 |
|---|---|---|---|
| TUSB2036IPWR | USB 2.0 transceiver with integrated 500 mA power switch; lacks VDET, RCP, and programmable OCP; only 5 V tolerant on VBUS. | Designed for USB 2.0 hub ICs; not suitable for standalone VBUS domain isolation or battery-supplied OTG hosts. | Select only if integrating into a USB 2.0 hub controller design where protocol handling is required alongside basic power switching. |
| TPS22965DSGR | 1.2 A load switch with 44 mΩ RON, but no VBUS-specific protection (no RCP, no VDET, no 30 V tolerance), and no ESD rating beyond HBM. | General-purpose power gating; requires external ESD protection and voltage monitoring circuitry for USB OTG use. | Choose when cost and RON are primary concerns and full USB OTG protection stack can be implemented externally. |

FAQ
What is the function of the ILIM pin on the NX5P1100UKZ?
The ILIM pin on the NX5P1100UKZ sets the overcurrent protection trigger threshold using an external resistor (40–300 kΩ). When EN is HIGH, the pin senses RILIM to define Itrig; when grounded, it activates a 10 mA constant-current source on VBUS. This dual-mode operation enables both programmable fault current limiting and low-power diagnostic current sourcing - a feature unique to the NX5P1100UKZ among comparable USB power switches.
Does the NX5P1100UKZ support reverse current protection, and how does it work?
Yes, the NX5P1100UKZ includes dedicated reverse bias current protection (RCP). It monitors the voltage difference between VBUS and VINT: if VBUS exceeds VINT by more than 30 mV for longer than 4 ms, or by more than 450 mV at any time, the switch opens and FAULT asserts LOW. This prevents back-driving the host supply - a critical requirement for USB OTG compliance - and distinguishes the NX5P1100UKZ from generic load switches lacking such USB-specific protection.
What is the purpose of the VDET pin on the NX5P1100UKZ?
The VDET pin on the NX5P1100UKZ provides an analog voltage output proportional to VBUS level (1.5–5.5 V range), enabling the host MCU to continuously monitor VBUS voltage without additional ADC circuitry. Unlike digital fault indicators, VDET allows precise state detection - e.g., distinguishing between no cable (VBUS = 0 V), attached peripheral (VBUS ≈ VINT), or overvoltage condition (VBUS > VINT + 450 mV) - which is essential for intelligent USB OTG role negotiation and safety diagnostics in the NX5P1100UKZ.
How does the NX5P1100UKZ behave when the EN pin is driven LOW?
When EN is driven LOW, the NX5P1100UKZ enters low-power mode: the N-channel MOSFET turns OFF, all protection circuits deactivate except undervoltage lockout (UVLO), ground current drops to 20 µA typical, and FAULT goes high-impedance unless UVLO is active. This state persists regardless of other conditions - except during overtemperature fault, where OTP remains active and overrides EN control. This behavior makes the NX5P1100UKZ suitable for battery-conscious USB OTG suspend/resume sequences.
What package type is used for the NX5P1100UKZ, and why is it suitable for portable designs?
The NX5P1100UKZ uses the WLCSP12 package: 1.36 × 1.66 × 0.51 mm, 0.4 mm ball pitch, with backside coating. Its ultra-compact size and low profile minimize PCB area and height - critical for slim smartphones and wearables. The wafer-level construction provides excellent thermal performance for its 100 mW power dissipation limit, and the 12-ball layout enables straightforward routing beneath the device, making it ideal for space-constrained portable USB OTG implementations.
