Product details
Overview
DPO2039DAB-13 from Diodes Incorporated is a 4-channel USB Type-C over-voltage protection IC designed to safeguard CC1/CC2 and DIFF1/DIFF2 signal lines against short-to-VBUS faults. It integrates four bidirectional OVP FETs with RDS(ON) of 300 mΩ (CC) and 5 Ω (DIFF), 100 ns OVP response time, and auto-recovery. Used in mobile phones and docking stations where VBUS shorts threaten USB PD controller and PHY interfaces.
For engineers reviewing the DPO2039DAB-13 datasheet, DPO2039DAB-13 pinout, DPO2039DAB-13 application, or DPO2039DAB-13 equivalent, key selection criteria include CC/DIFF channel-specific OVP thresholds (6.0 V / 4.5 V), differential crosstalk (-80 dB), thermal shutdown at +150 °C, and U-QFN3030-16 (Type B) package compatibility with high-density USB-C port layouts.
Technical Context
The DPO2039DAB-13 implements two independent OVP pairs: one for CC pins (threshold 6.0 V, hysteresis 140 mV) and one for DIFF pins (threshold 4.5 V, hysteresis 110 mV), each with dedicated MOSFET switches and fault detection logic. Its FAULTB output is an active-low open-drain signal asserting within 300 μs of OVP detection.
Power is sourced from VSYS (2.7–5.5 V), enabling operation during battery depletion via back-fed power from the USB-C connector. The device supports hot-plug tolerance up to 24 V on CC/DIFF pins and clamps system-side voltage to ≤7 V during VBUS shorts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OVP Threshold (CC) | 6.0 V typical - triggers protection before USB PD VBUS (20 V) damages sub-micron CC interface circuitry |
| OVP Threshold (DIFF) | 4.5 V typical - matches USB 2.0 differential signaling range while preventing VBUS coupling damage |
| RDS(ON) (CC path) | 300 mΩ typical - minimizes voltage drop and insertion loss for CC line communication integrity |
| RDS(ON) (DIFF path) | 5 Ω typical - balances low ON-resistance with ESD robustness for high-speed differential signals |
| Response Time | <100 ns - isolates system-side components faster than EOS pulse duration in real-world cable shorts |
| Bandwidth (CC) | 200 MHz - preserves USB PD CC logic timing and voltage-level transitions without distortion |
| Bandwidth (DIFF) | 1000 MHz - maintains signal fidelity for USB 2.0 full-speed (480 Mbps) differential data paths |
Pinout & Package
The DPO2039DAB-13 is housed in a 3.0 mm × 3.0 mm × 0.55 mm U-QFN3030-16 (Type B) package with exposed thermal pad, optimized for compact USB-C port routing and thermal dissipation in space-constrained mobile designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | DIFF1C, DIFF2C, CC1C, CC2C | Connector-side I/O pins - directly connect to USB-C receptacle DIFF/CC pins; rated for 24 V short-to-VBUS |
| 9, 10, 11, 12 | DIFF1S, DIFF2S, CC1S, CC2S | System-side I/O pins - interface to USB PD controller or PHY; clamped to ≤7 V during OVP events |
| 7 | CB | ESD support capacitor terminal - requires 0.1 μF to GND to stabilize internal ESD clamp network |
| 8 | FAULTB | Active-low open-drain fault flag - asserts low within 300 μs of OVP detection; pulled up externally to 2.7–5.5 V rail |
| 14 | GND | Signal and thermal reference - must be connected to PCB ground plane; ties to exposed pad for thermal conduction |
| 15 | VSYS | Main supply input - powers internal logic and gate drivers; operates from 2.7–5.5 V, including battery-depleted back-feed |
Key Features
| Feature | Design Value |
|---|---|
| Auto-recovery OVP | CC/DIFF channels restore signal path after 32 ms (CC) or 32 ms (DIFF) once overvoltage clears - eliminates manual reset requirement |
| IEC 61000-4-2 ESD protection | ±2.0 kV HBM on all CC/DIFF pins - meets industrial-grade ESD immunity without external TVS diodes |
| Thermal shutdown | +150 °C trip with +20 °C hysteresis - prevents latch-up or permanent damage during sustained overload conditions |
| Low leakage current | <35 μA per channel at 3.6 V - avoids signal degradation or false OVP triggering in low-power USB suspend states |
Applications
| USB-C Mobile Phone Charging Port | USB-C Docking Station Hub |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C over-voltage protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB544RGER | Single-channel USB 3.1 Gen1 re-driver with integrated OVP; no DIFF-pair protection; 8.5 GHz bandwidth | Targets high-speed SuperSpeed data lanes only; lacks dual-pair CC+DIFF coverage | Select when protecting USB 3.x SS lines is primary need; not suitable for full USB-C port CC/DIFF co-protection |
| TPD6S300ARVCR | 6-channel USB-C protection with 1.5 pF CIN on CC lines; no DIFF protection; 3.3 V fixed supply | Optimized for CC-only protection in cost-sensitive notebooks; no support for USB 2.0 DIFF path | Choose for CC-only designs with strict capacitance budget (<2 pF); cannot replace DPO2039DAB-13 where DIFF line protection is required |
Compared with TUSB544RGER and TPD6S300ARVCR, the DPO2039DAB-13 uniquely delivers simultaneous, independent OVP for both CC and DIFF signal pairs in a single 3×3 mm package-enabling complete USB-C port-level protection without sacrificing bandwidth or adding board area.

FAQ
What is the maximum VBUS short voltage the DPO2039DAB-13 can withstand on CC pins?
The DPO2039DAB-13 supports short-to-VBUS tolerance up to 24 V on CC1C/CC2C pins, verified with 1-meter USB-C cable and 30 Ω load on CCxS. During such events, it clamps system-side voltage to ≤7 V and isolates within 100 ns to prevent damage to downstream USB PD controllers.
Does the DPO2039DAB-13 require external pull-up resistors on FAULTB?
Yes - FAULTB is an open-drain output requiring an external pull-up resistor (typically 10 kΩ) to a 2.7–5.5 V rail. This ensures proper logic-high level when no fault is present and enables wired-OR fault signaling across multiple protection ICs in multi-port systems.
Can the DPO2039DAB-13 operate without VSYS when the system battery is fully depleted?
Yes - when VSYS is absent, the DPO2039DAB-13 draws operating power from the USB-C connector side via CC/DIFF pins, enabling protection during battery-dead hot-plug scenarios. This back-fed operation is validated for VCCxC/VDIFFxC ≥2.7 V and supports full OVP functionality.
How does the DPO2039DAB-13 handle crosstalk between DIFF1 and DIFF2 channels?
The DPO2039DAB-13 achieves -80 dB crosstalk between DIFF1S and DIFF2C (or vice versa) at 1 MHz, measured with common-mode voltages of 3.6 V and 0.3 V. This isolation level prevents signal corruption in dual-lane USB 2.0 configurations and ensures reliable data transmission during simultaneous DIFF line activity.
