Product details
Overview
NX5P3201CUKAZ 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 reverse current protection - deployed in smartphone battery charging and system power rail control.
For engineers reviewing the NX5P3201CUKAZ datasheet, NX5P3201CUKAZ pinout, NX5P3201CUKAZ application, or NX5P3201CUKAZ equivalent, key selection criteria include dual-switch coordination, slew-rate-controlled soft-start timing (26.5 ms), open-drain ACOK status signaling, and 28 V tolerant VBUS handling - critical for USB Type-C port power management in portable devices.
Technical Context
The NX5P3201CUKAZ implements two independent control paths: SWP uses ENP to manage bidirectional conduction between VBUS and PMU under UVLO/UVLO hysteresis (100 mV) and OVLO (6.55 V/6.45 V), while SW5 uses EN5 to control VIN-to-VBAT switching with RCP activation at VBAT − VI ≥ 30 mV and UVLO at 2.5 V. Both channels feature deglitching (15 ms UVLO turn-on delay) and thermal shutdown with automatic recovery.
SWP supports automatic operation modes (USB charging vs. OTG) based on relative voltage levels at VBUS and PMU, with ACOK output reflecting SWP state (LOW when closed, high-Z during protection events). SW5 includes reverse current blocking that isolates VBAT from VIN when input voltage drops below VBAT by 35 mV for >4 ms - preventing backdrive into upstream power sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| SWP Continuous Current | 3 A - supports full USB BC1.2 charging and OTG host mode without external FETs |
| SW5 Continuous Current | 6 A - enables high-current system rails (e.g., display backlight, modem power) |
| ON Resistance (SWP) | 32 mΩ typical - minimizes voltage drop and power loss at 3 A load (≤96 mV drop) |
| ON Resistance (SW5) | 8 mΩ typical - limits conduction loss to ≤48 mV at 6 A, reducing thermal stress |
| OVLO Threshold | 6.55 V - protects downstream circuitry from overvoltage transients on USB VBUS |
| UVLO Threshold (SWP) | 3.2 V - prevents unreliable switching during brown-out conditions on VBUS/PMU |
| Soft-Start Time | 26.5 ms - controls inrush current into capacitive loads (e.g., USB port decoupling) |
Pinout & Package
Package: WLCSP30 (2.26 × 2.56 × 0.51 mm, backside coating included); 30-bump wafer-level chip-scale package with solder bumps arranged in 5×6 grid.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBUS (C3,C4,D3,D4,E3,E4,E5) | SWP input/output | 28 V tolerant node for USB power path; connects to upstream USB connector |
| PMU (C5,C6,D5,D6,E6) | SWP input/output | Bidirectional port for device-side USB power management (OTG/charging) |
| VIN (A1,B1,B2,B3,B4) | SW5 input | 2.7–5.5 V supply input for high-side load switch; powers system rails |
| VBAT (A2,A3,A4,A5,B5) | SW5 output | Switched output delivering up to 6 A to load; isolated during RCP/UVLO |
| ACOK (B6) | Status indicator | Open-drain output (active LOW when SWP closed); requires external 10–200 kΩ pull-up |
| EN5 (C1) | SW5 enable | Active HIGH control for 6 A load switch; disabled during UVLO/RCP/OTP |
| ENP (E1) | SWP enable | Active HIGH control for 3 A bidirectional switch; modulates USB power routing |
| GND (C2,D1,D2,E2) | Ground reference | Common 0 V return for both switches; multiple pins reduce impedance and improve thermal dissipation |
| n.c. (A6) | No connection | Unused bump; must be left unconnected on PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-switch architecture | Combines USB OTG/charger switch and high-current load switch in one die - eliminates discrete FET + controller solutions |
| Slew-rate controlled soft-start | 26.5 ms controlled ramp prevents inrush-induced voltage droop on shared power rails |
| Reverse current protection (RCP) | Blocks backdrive from VBAT to VIN when ΔV ≥ 30 mV - protects battery and PMIC during sleep states |
| Overvoltage lockout (OVLO) | Disables SWP at VBUS > 6.55 V and holds ACOK in high-Z - safeguards USB PHY and LDOs |
| ESD robustness | 8 kV IEC61000-4-2 contact discharge on VBUS - meets industrial-grade USB port ESD requirements |

FAQ
What is the maximum continuous current rating for each switch in the NX5P3201CUKAZ?
The NX5P3201CUKAZ supports 3 A continuous current through its SWP (USB power switch) channel and 6 A continuous current through its SW5 (high-side load switch) channel, both rated at Tamb = 85 °C per the datasheet limiting values table. These ratings are validated with proper PCB thermal design using multi-layer copper planes.
Does the NX5P3201CUKAZ require external components for basic operation?
Yes - the NX5P3201CUKAZ requires an external pull-up resistor (10–200 kΩ) on the ACOK pin to generate a valid logic-level status signal. No external gate resistors or bootstrap capacitors are needed, as soft-start, protection circuits, and level-shifting are fully integrated within the NX5P3201CUKAZ die.
How does the NX5P3201CUKAZ handle overvoltage on the VBUS pin?
The NX5P3201CUKAZ disables the SWP channel when VBUS exceeds 6.55 V via its integrated OVLO circuit, isolating VBUS from PMU and placing the ACOK output in high-impedance state. Recovery occurs automatically when VBUS falls below 6.45 V and no other protection flags are active - all implemented internally without firmware dependency.
Can the NX5P3201CUKAZ be used in USB On-The-Go (OTG) applications?
Yes - the NX5P3201CUKAZ is explicitly designed for USB OTG operation. Its SWP channel automatically detects and configures bidirectional power flow between VBUS and PMU based on relative voltage levels, enabling seamless role switching between host and peripheral modes as defined in USB OTG specifications.
What is the purpose of the n.c. (no connection) bump on the NX5P3201CUKAZ WLCSP30 package?
The n.c. bump (A6) on the NX5P3201CUKAZ is an unconnected silicon pad with no internal circuit connection. It must remain unpopulated on the PCB - no solder paste or trace should be placed at this location to avoid unintended shorts or mechanical stress during reflow soldering of the WLCSP30 package.
