Product details
Overview
MP5030CGQH-Z from Monolithic Power Systems is a USB charging port controller integrating a 3A current-limit switch and BC1.2/CDP/DCP/QC3.0 auto-detection circuitry. It delivers programmable current limiting (up to 3.35A typical), 32mΩ RDS(ON), line drop compensation for 5V outputs, and supports DCP with QC3.0 or CDP mode via MODE pin control - deployed in automotive USB car chargers and embedded host ports.
For engineers reviewing the MP5030CGQH-Z datasheet, MP5030CGQH-Z pinout, MP5030CGQH-Z application, or MP5030CGQH-Z equivalent, this device enables robust USB power delivery with protocol-agnostic port identification, precise 5V regulation under load, and integrated OVP/thermal/hiccup protection - critical for automotive-grade USB charging systems requiring BC1.2 compliance and QC3.0 interoperability.
Technical Context
The MP5030CGQH-Z implements dual-stage UVLO (3.0V and 3.9V thresholds), internal soft-start (290µs), and adaptive ADJ-based line drop compensation delivering +220mV at 2.4A to maintain stable 5V at the load. Its MODE pin selects between CDP (low), DCP-with-QC (high), or DCP-without-QC (float), enabling seamless handshaking with legacy and fast-charging devices without firmware intervention.
It integrates a 32mΩ NMOS power switch with hiccup-mode overcurrent protection (2ms on / 2s off), input OVP (115% VIN threshold with 10µs deglitch), and thermal shutdown at 160°C (35°C hysteresis). The DP/DM data path supports full USB 2.0 signaling in CDP mode with <5.8ms VDM_SRC activation timing and 500MHz analog bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 3A - Sustains full USB-C PD-compatible loads without external heatsinking in QFN-10 package. |
| RDS(ON) | 32mΩ typical - Minimizes conduction loss and self-heating at 3A (≤288mW dissipation). |
| Input Voltage Range | Up to 14V - Supports 5V/9V/12V QC3.0 input rails and automotive battery transients. |
| Current Limit Accuracy | ±6.7% (3.13–3.57A at RILIM=1.5kΩ) - Enables precise ILIM setting for BOM margining. |
| Line Drop Compensation | +220–350mV at 2.4A - Compensates for ≥150mΩ PCB trace resistance to hold 5V ±2% at connector. |
| MODE Pin Logic | Low = CDP, Float = DCP-no-QC, High = DCP+QC - Hardware-selectable USB role without MCU involvement. |
| Thermal Shutdown | 160°C with 35°C hysteresis - Prevents permanent damage during sustained overload or poor airflow. |
Pinout & Package
MP5030CGQH-Z is housed in a thermally enhanced QFN-10 (1.5mm × 2mm, 0.5mm pitch) package with exposed thermal pad. The 10-pin layout supports compact 2-layer PCB designs and requires vias under the pad for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 DP | D+ data line to USB connector | Bi-directional handshake signal for BC1.2/CDP/DCP detection; routed directly to downstream port. |
| 2 DM | D− data line to USB connector | Bi-directional handshake signal; used with DP for voltage divider, 1.2V/1.2V, and QC3.0 negotiation. |
| 3 ILIM | Current limit set input | Connects to GND via resistor (e.g., 1.5kΩ → 3.35A); sets high-accuracy foldback threshold. |
| 4 ADJ | Voltage adjustment & line compensation | Sinks 500µA to upstream DC/DC FB node to regulate output and compensate for IR drop. |
| 5 MODE | USB mode selection | Hardware-configured: low = CDP, float = DCP-no-QC, high = DCP+QC; internal 1MΩ pull-up to 1.2V. |
| 6 GND | Power and signal ground | Common reference for all analog/digital blocks; must be low-impedance connection to thermal pad. |
| 7 IN | Input supply (up to 14V) | Accepts buck/boost/AC-DC converter output; feeds internal regulator and power MOSFET. |
| 8 OUT | Switched output to USB VBUS | Drives USB connector with current-limited 5V; connects to ceramic output capacitor (22µF recommended). |
| 9 DM_OUT | D− to USB host controller | Passes DM signal through internal analog switch in CDP mode; isolated from DP/DM during QC negotiation. |
| 10 DP_OUT | D+ to USB host controller | Direct pass-through in CDP mode; bypasses internal logic to preserve USB 2.0 signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| QC3.0 Protocol Support | Full hardware-based negotiation (3.6–12V), including VDAT_REF (0.3V), VSEL_REF (2.0V), and glitch timing compliance. |
| BC1.2 Compliance | Supports DCP (divider/1.2V/1.2V modes) and CDP schemes per YD/T 1591-2009 and USB-IF BC1.2 spec. |
| Integrated Protection | Hiccup OCP (2ms/2s), input OVP (115% VIN), thermal shutdown (160°C), and fast short-circuit cutoff (700ns). |
| Line Drop Compensation | Linear +220mV at 2.4A ensures ≤2% VBUS deviation across 150mΩ trace resistance at full load. |
| Low Quiescent Current | 320µA typical at 5V - minimizes standby power loss in always-on automotive USB ports. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB charging port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65987D | USB-C PD controller with integrated MCU, supports USB-C, higher integration but requires firmware development. | Targets USB-C ecosystems only; lacks native BC1.2 DCP/CDP support without custom code. | Choose for USB-C PD 3.0 designs needing programmable policy engine; avoid for cost-sensitive USB-A BC1.2 systems. |
| IP2721 | Dedicated QC3.0/BC1.2 controller with fixed 5V/9V/12V outputs; no adjustable current limit or line compensation. | Supports QC3.0 and DCP but omits CDP mode and ADJ-based VBUS regulation. | Choose when only QC/DCP functionality is needed and board space permits discrete current-limit switch. |
Compared with TPS65987D and IP2721, the MP5030CGQH-Z uniquely combines hardware-only BC1.2 CDP/DCP/QC3.0 detection, programmable current limiting, and analog line drop compensation in a 10-pin QFN - making it optimal for USB-A automotive and embedded applications where MCU-free, low-BOM-cost, and 5V stability are mandatory.

FAQ
What USB charging protocols does MP5030CGQH-Z support natively?
The MP5030CGQH-Z supports BC1.2-compliant Dedicated Charging Port (DCP) and Charging Downstream Port (CDP) modes, plus Qualcomm Quick Charge 3.0 (and backward-compatible QC 2.0) - all implemented in hardware with no firmware or host processor required. It detects and configures automatically based on DP/DM voltage signatures and MODE pin state.
How is line drop compensation implemented, and what is its effective range?
Line drop compensation is achieved via the ADJ pin, which sinks a controlled current (500µA typical) from the upstream DC/DC converter's feedback node. This increases the converter's output voltage linearly with load current - delivering +220mV at 2.4A and up to +350mV - compensating for up to ~150mΩ of total trace resistance while maintaining 5V ±2% at the USB connector.
Can MP5030CGQH-Z operate in CDP mode with full USB 2.0 data throughput?
Yes. In CDP mode (MODE pin pulled low), DP is directly routed to DP_OUT and DM is internally switched to DM_OUT with 500MHz analog bandwidth and <5.8ms VDM_SRC activation timing. This preserves USB 2.0 signal integrity for enumeration and high-speed data transfer while providing regulated, current-limited 5V VBUS with line compensation.
What is the maximum continuous current and how is it set?
The MP5030CGQH-Z delivers up to 3A continuous output current with 32mΩ RDS(ON). The current limit threshold is set externally using a resistor from ILIM to GND: a 1.5kΩ resistor yields 3.35A typical (range 3.13–3.57A). The device enters hiccup-mode OCP if VOUT drops below 3.5V for 2ms under overload.
Does MP5030CGQH-Z include overvoltage protection, and how does it behave during QC3.0 voltage transitions?
Yes - it features dynamic input OVP with 115% VIN threshold (e.g., 11.5V at 10V input) and 10µs deglitch. During QC3.0 voltage slewing (e.g., 5V→9V), OVP is blanked to prevent false triggering; the internal discharge path (72Ω) activates only during high-to-low transitions to safely dissipate stored energy before re-enabling the switch.
Is thermal management supported, and what is the junction temperature limit?
The device includes thermal shutdown at 160°C with 35°C hysteresis, and its QFN-10 (1.5mm×2mm) package features an exposed thermal pad. With proper PCB layout - including ≥4 thermal vias under the pad and 2oz copper - it sustains 3A continuous current at +85°C ambient without derating, verified per JEDEC JESD51-7 thermal testing.
What are the key PCB layout requirements for stable operation?
Critical layout practices include: (1) placing 22µF ceramic input/output capacitors within 2mm of IN/GND and OUT/GND pins; (2) routing IN/OUT traces wide and short with multiple vias; (3) keeping the ADJ trace to the upstream FB pin <5mm and shielded from noise; (4) connecting the thermal pad to solid GND plane with ≥4 thermal vias (0.3mm diameter, 1mm spacing).
