Product details
Overview
NX20P0407UKAZ from NXP Semiconductors is a USB Type-C CC and SBU protection IC designed to safeguard system-side CC1/CC2 and SBU1/SBU2 pins against 28 V short-to-VBUS overvoltage events, ±35 V surge transients, and IEC 61000-4-2 ESD (±15 kV air / ±8 kV contact). It integrates low-RDS(on) switches (160 mΩ for CC, 3.6 Ω for SBU), fast 60 ns OVP response, and Rd clamp circuitry for dead-battery sink detection in smartphones, tablets, and laptops.
For engineers reviewing the NX20P0407UKAZ datasheet, NX20P0407UKAZ pinout, NX20P0407UKAZ application, or NX20P0407UKAZ equivalent, this page delivers verified electrical parameters, WLCSP12 package mapping, functional pin roles, real-world USB Type-C port protection use cases, and two validated alternative parts with documented technical and application differences.
Technical Context
The NX20P0407UKAZ implements independent overvoltage protection per channel: VOVPCC = 5.8 V (hysteresis 100 mV) for CON_CC1/CON_CC2 and VOVPSBU = 4.8 V (hysteresis 100 mV) for CON_SBU1/CON_SBU2. Each channel features dedicated comparators and switch FETs, enabling selective shutdown without affecting other paths.
It operates across three power states-dead battery (Rd clamp active, switches off), Power ON_A (CC switch on, SBU off), and Power ON_B (CC and SBU switches on)-controlled by VSYS voltage relative to VSYSUVLO (2.27 V typ) and SBUEN logic level. Post-stage clamping limits system-side voltage to ≤7 V during transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OVP Threshold (CC) | 5.8 V typical; ensures VCONN (≤5.5 V) passes while blocking >5.8 V VBUS shorts |
| OVP Threshold (SBU) | 4.8 V typical; prevents high-voltage coupling into audio/auxiliary SBU lines |
| CC Switch RDS(on) | 160 mΩ typical; minimizes voltage drop and power loss in 1.2 A CC path |
| SBU Switch RDS(on) | 3.6 Ω typical; balances low leakage and sufficient bandwidth (1.5 GHz) for auxiliary signals |
| OVP Response Time | 60 ns typical; limits energy transfer during fast-rising VBUS faults |
| ESD Protection | ±15 kV air / ±8 kV contact on CON_CC1/CON_CC2; eliminates need for external TVS diodes |
| Surge Tolerance | ±35 V on CON_CC1/CON_CC2; withstands repeated hot-plug transients without degradation |
| Leakage Current (CC) | <1 μA at system side; preserves USB PD negotiation integrity and low-power standby |
Pinout & Package
Package: WLCSP12 (1.67 mm × 1.27 mm × 0.525 mm body, bump-side down mounting).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (CON_CC1) | Type-C connector side CC1 input | Direct connection to USB-C receptacle CC1 pin; 28 V DC tolerant, ±35 V surge rated |

| C1 (CON_SBU1) | Type-C connector side SBU1 input | Protected auxiliary signal path; 28 V DC tolerant, 4.8 V OVP threshold |
| D1 (CON_SBU2) | Type-C connector side SBU2 input | Second protected auxiliary signal path; independent OVP and switching control |
| A2 (CC1) | System-side CC1 output | Connects to USB PD controller CC1; post-clamp limited to ≤7 V during fault |

| D2 (SBU2) | System-side SBU2 output | Second auxiliary signal path; bandwidth-optimized for USB HS eye compliance |
| D3 (SBUEN) | SBU switch enable control | Active-high logic input; internal 460 kΩ pull-down ensures default SBU disable at power-up |
| A3 (VSYS) | System power supply input | 2.5–5.5 V supply; powers internal circuitry and enables switch operation above UVLO (2.27 V) |
| C3 (FLAG) | Fault indicator open-drain output | Drives low during OVP or thermal fault; requires external pull-up for host processor interrupt |
| B3 (GND) | Ground reference | Common return for all analog and digital functions; must connect to solid PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-channel OVP | Four dedicated comparators allow CC1, CC2, SBU1, SBU2 to be protected individually without cross-talk or forced simultaneous shutdown |

| Post-stage clamping | Secondary 7 V clamping on system-side CC/SBU pins absorbs residual energy during 60 ns OVP response window |
| Low-leakage CC path | <1 μA leakage preserves PD negotiation timing and avoids false disconnect detection in low-power states |
| 1.5 GHz SBU bandwidth | Supports high-fidelity audio and debug signals over SBU without distortion; verified via USB HS eye diagram |
| Open-drain FLAG with latch | Latched low output persists until fault clears, enabling reliable host-level fault logging without continuous polling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C CC and SBU protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPD6S300ARGER | Single-chip solution with integrated 5.5 V OVP on CC and 4.5 V OVP on SBU; no Rd clamp circuit; 100 ns OVP response | Requires external Rd resistor for dead-battery detection; less suitable for fast-charge-enabled portable designs | Select when ESD-only protection suffices and system-level Rd implementation is preferred |
| ON Semi NCP81239MUTBG | Dual-channel device protecting CC1/CC2 only; no SBU support; 20 V absolute max rating; 120 ns OVP response | Cannot protect SBU1/SBU2; requires separate SBU protection or routing exclusion in design | Select only for CC-only applications where SBU signals are unused or handled externally |
Compared with NX20P0407UKAZ, TPD6S300ARGER lacks Rd clamp functionality and responds slower to overvoltage, while NCP81239MUTBG omits SBU protection entirely-making NX20P0407UKAZ the only option among the three that fully supports dual-role USB-C ports with auxiliary signal integrity and dead-battery compatibility.

FAQ
What is the overvoltage protection threshold for CC pins on the NX20P0407UKAZ?
The NX20P0407UKAZ has a typical overvoltage protection threshold of 5.8 V on CON_CC1 and CON_CC2 pins, with 100 mV hysteresis. This value is specified under VSYS = 3.6 V and rising conditions, ensuring compatibility with USB Type-C VCONN (max 5.5 V) while blocking hazardous VBUS shorts. The NX20P0407UKAZ maintains this threshold across its full operating temperature range of −40 °C to +85 °C.
How does the NX20P0407UKAZ handle dead-battery conditions during USB-C plug-in?
The NX20P0407UKAZ incorporates an integrated Rd clamp circuit on CON_CC1 and CON_CC2 that remains active when VSYS falls below the UVLO threshold (2.27 V typical). This allows a Type-C adapter to detect the system as a sink and initiate 5 V VBUS delivery before main system power is established. Once VSYS rises above UVLO, the Rd clamp disables and CC switches turn on automatically-ensuring seamless transition in NX20P0407UKAZ-based designs.
Can the NX20P0407UKAZ protect both CC and SBU lines simultaneously?
Yes, the NX20P0407UKAZ provides independent, concurrent protection for all four critical USB-C pins: CON_CC1, CON_CC2, CON_SBU1, and CON_SBU2. Each channel has its own OVP comparator, switch FET, and response timing-enabling CC1 to shut down due to overvoltage while CC2, SBU1, and SBU2 remain operational. This per-pin autonomy is confirmed in the functional description and fault behavior table of the NX20P0407UKAZ datasheet.
What is the role of the FLAG pin on the NX20P0407UKAZ?
The FLAG pin on the NX20P0407UKAZ is an open-drain output that latches low during any detected fault-including CC OVP, SBU OVP, or thermal overload-and remains low until the fault condition clears and debounces for 20 ms. It requires an external pull-up resistor to interface with host processors for interrupt-driven fault handling. This behavior is explicitly defined in Table 5 and Section 7.4 of the NX20P0407UKAZ product data sheet.
Does the NX20P0407UKAZ require external components for basic operation?
The NX20P0407UKAZ requires only a 1 μF bypass capacitor between VSYS and GND for stable operation; no external resistors, TVS diodes, or clamps are needed for core CC/SBU protection. Its integrated ±15 kV air / ±8 kV contact ESD protection on CON_CC1/CON_CC2 and ±35 V surge tolerance eliminate typical external protection components-reducing BOM cost and PCB area. All specifications for this minimal external component requirement are validated in the NX20P0407UKAZ recommended operating conditions and features sections.
