Product details
Overview
NX5P3201CUKZ from NXP Semiconductors is a dual-channel power switch integrating a 3 A bidirectional USB OTG/charger port switch (SWP) and a 6 A high-side load switch (SW5) in a single WLCSP30 package. It delivers 32 mΩ typical ON resistance for SWP and 8 mΩ for SW5, with integrated UVLO (3.2 V), OVLO (6.55 V), OTP (130 °C), and RCP (30 mV threshold), enabling robust power path control in portable battery-powered devices.
For engineers reviewing the NX5P3201CUKZ datasheet, NX5P3201CUKZ pinout, NX5P3201CUKZ application, or NX5P3201CUKZ equivalent, key selection criteria include dual-switch coordination, slew-rate-controlled soft-start for 100 µF+ capacitive loads, open-drain ACOK status indicator timing, and WLCSP30 thermal performance under 85 °C ambient operation.
Technical Context
The NX5P3201CUKZ implements two independent protection-controlled power paths: SWP uses dual-input (VBUS/PMU) bidirectional switching with 15 ms UVLO deglitching and OVLO-triggered isolation above 6.55 V; SW5 employs reverse current detection at VBAT − VIN ≥ 30 mV and UVLO activation below 2.5 V on VIN. Both switches feature slew-rate-limited turn-on to limit inrush current during hot-swap events.
Control logic is strictly input-driven: ENP enables SWP only when UVLO/OVLO/OTP are inactive; EN5 enables SW5 only when UVLO/OTP/RCP conditions are satisfied. The ACOK output reflects SWP status exclusively - pulled low when SWP is closed, high-impedance during any SWP fault or disable - and requires an external 10–200 kΩ pull-up resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| SWP Continuous Current | 3 A at 85 °C ambient - supports USB charging and OTG host mode with sustained 5 V/3 A power delivery |
| SW5 Continuous Current | 6 A at 85 °C ambient - powers high-current subsystems (e.g., display backlight, RF PA) directly from battery rail |
| ON Resistance (SWP) | 32 mΩ typical at 5 V - limits conduction loss to <150 mW at 3 A, critical for thermal management in compact WLCSP |
| ON Resistance (SW5) | 8 mΩ typical at 5 V - reduces voltage drop to <48 mV at 6 A, preserving system efficiency in high-side load switching |
| UVLO Threshold (SWP) | 3.2 V (typical) with 100 mV hysteresis - prevents erratic switching during battery brownout or USB voltage instability |
| OVLO Threshold (SWP) | 6.55 V (typical) with 100 mV hysteresis - isolates VBUS above safe USB PD levels, protecting downstream circuitry |
| RCP Threshold (SW5) | 30 mV (typical) between VBAT and VIN - blocks reverse current flow before battery backdrive damages input regulators |
| ACOK Output Type | Open-drain, active-low status indicator - signals SWP closure state to host controller without level-shifting components |
Pinout & Package
Package: WLCSP30 (Wafer Level Chip-Scale Package), 2.26 × 2.56 × 0.51 mm, 30-bump array with backside coating. Compatible with standard reflow soldering per J-STD-020D MSL-1 profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBUS (C3,C4,D3,D4,E3,E4,E5) | SWP input/output (USB VBUS side) | Bidirectional 28 V-tolerant terminal for USB charging/OTG; connects to USB connector VBUS line |
| PMU (C5,C6,D5,D6,E6) | SWP input/output (PMU side) | Bidirectional terminal for PMU rail; enables USB OTG host mode when VBUS < PMU |
| VIN (A1,B1,B2,B3,B4) | SW5 input (battery or supply rail) | High-side switch input; accepts 2.7–5.5 V; must exceed VUVLO (2.5 V) before EN5 enables conduction |
| VBAT (A2,A3,A4,A5,B5) | SW5 output (load side) | Delivers switched power to load; RCP activates if VBAT exceeds VIN by >30 mV |
| ACOK (B6) | SWP status indicator | Open-drain output; LOW = SWP closed; high-Z = SWP disabled/faulted; requires external pull-up |
| EN5 (C1) | SW5 enable input | Active-HIGH control; overrides UVLO/RCP/OTP only when all protections are inactive |
| ENP (E1) | SWP enable input | Active-HIGH control; enables SWP only after UVLO stabilization (15 ms delay) and absence of OVLO/OTP |
| GND (C2,D1,D2,E2) | Ground reference | Common return for both switches; multiple GND bumps ensure low-impedance thermal and signal path |
| n.c. (A6) | No-connect | Unused bump; must be left unconnected on PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent protection domains | SWP and SW5 each have dedicated UVLO, OTP, and fault response - eliminates cross-domain interference during fault events |
| Slew-rate controlled soft-start | 26.5 ms typical turn-on time for SWP - limits inrush current to safe levels even with 100 µF+ output capacitance |
| Reverse current blocking | 30 mV threshold with 35 mV hysteresis on SW5 - prevents battery backdrive into input rails without external diodes |
| ESD robustness | 8 kV IEC61000-4-2 contact discharge on VBUS - withstands real-world USB connector handling without external TVS |
| Wide input tolerance | 28 V max on VBUS - supports legacy USB chargers and transient overvoltage events up to automotive-level stress |
| Thermal shutdown recovery | 130 °C trip / 110 °C release for SWP - provides automatic fault recovery without host intervention after cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS22965DSGR | Single 6 A load switch only; no USB bidirectional SWP or ACOK output; 12 mΩ RON; no OVLO/UVLO on input | Requires external USB switch and protection IC for OTG/charging - increases board area and complexity | Select when only high-side load switching is needed and USB path is handled separately |
| ON Semi NCP3902MUTBG | Dual 4.5 A switches with shared enable; no RCP; no ACOK; 15 mΩ/15 mΩ RON; UVLO only on main input | Lacks independent SWP/SW5 control and reverse current blocking - unsuitable for battery-backdrive-sensitive designs | Consider only for cost-sensitive applications where RCP and bidirectional USB are not required |
Compared with TPS22965DSGR and NCP3902MUTBG, the NX5P3201CUKZ uniquely integrates USB-specific protection (OVLO/UVLO/ACOK) and asymmetric current capability (3 A + 6 A) in one die, eliminating inter-IC timing mismatches and reducing total solution size by 35% in portable USB devices.

FAQ
What is the maximum allowable voltage on the VBUS pin of the NX5P3201CUKZ?
The NX5P3201CUKZ supports up to +29 V on the VBUS pin per absolute maximum ratings, but its OverVoltage LockOut (OVLO) circuit activates at 6.55 V typical to isolate the pin. Operation above 6.55 V triggers automatic shutdown of SWP and places ACOK in high-impedance state. For continuous operation, VBUS must remain within 3.4 V to 28 V as specified in recommended conditions.
How does the ACOK output behave when the NX5P3201CUKZ enters overtemperature protection?
When the NX5P3201CUKZ SWP junction temperature exceeds 130 °C, its OverTemperature Protection (OTP) circuit disables SWP and forces the ACOK output into high-impedance state - identical to its behavior during OVLO or UVLO faults. ACOK remains high-Z until temperature drops below 110 °C and ENP is held HIGH, at which point ACOK transitions to LOW if SWP closes successfully.
Can the NX5P3201CUKZ be used without an external pull-up resistor on the ACOK pin?
No - the ACOK pin of the NX5P3201CUKZ is an open-drain output requiring an external pull-up resistor between 10 kΩ and 200 kΩ connected to a logic-compatible voltage rail (e.g., 1.8 V or 3.3 V). Without this resistor, ACOK cannot assert a valid LOW state when SWP is closed, breaking host-controller status monitoring and violating the functional specification.
What is the purpose of the 15 ms turn-on delay in the NX5P3201CUKZ UVLO circuit?
The 15 ms turn-on delay in the NX5P3201CUKZ UVLO circuit serves as a deglitch function to prevent false triggering caused by transient ringing on VBUS or PMU lines during connector insertion or voltage transients. It ensures SWP only enables after the applied voltage stabilizes above VUVLO (3.2 V) for 15 consecutive milliseconds, guaranteeing reliable USB enumeration and power negotiation.
Does the NX5P3201CUKZ support simultaneous operation of both SWP and SW5 switches?
Yes - the NX5P3201CUKZ allows fully independent operation of SWP and SW5. ENP controls SWP while EN5 controls SW5; their protection circuits (UVLO/OVLO/OTP for SWP; UVLO/OTP/RCP for SW5) operate autonomously. No internal dependency exists between the two switches, enabling concurrent USB charging (SWP closed) and display backlight powering (SW5 closed) in smartphone designs.
