Monolithic Power Systems Inc. EV5030D-QH-00A

Overview

EV5030D-QH-00A from Monolithic Power Systems is an evaluation board for the MP5030D USB charging port controller IC, integrating a 3A current-limit switch and BC1.2-compliant CDP/DCP port identification circuitry. It operates across 12V input, delivers regulated 5V output, supports automatic mode detection (CDP, DCP, Divider, 1.2V/1.2V), and includes hiccup current limiting, input OVP, and thermal shutdown.

For engineers reviewing the EV5030D-QH-00A datasheet, EV5030D-QH-00A pinout, EV5030D-QH-00A application, or EV5030D-QH-00A equivalent, this board enables rapid validation of MP5030D's USB charging port auto-detection, load current sensing, status signaling, and fault protection in real-world host-side USB power delivery designs.

Technical Context

The EV5030D-QH-00A implements a complete reference design for MP5030D - a QFN-10 (1.5mm × 2mm) USB current limit switch with integrated BC1.2 port classification logic. It interfaces directly with a 12V input via MP2499M buck converter (U1), delivering stable 5V to the MP5030D (U2) and downstream USB Type-A port.

Board-level configuration supports CDP mode by default (MODE pin pulled to GND via JP1), while DCP mode requires floating MODE and resistor replacement (R9/R10 → 0Ω). STATUS pin provides open-drain fault/status indication, and EN enables/disables the MP5030D independently.

FAQ

What is the primary function of the EV5030D-QH-00A?

The EV5030D-QH-00A is an evaluation board for the MP5030D IC, enabling engineers to validate USB charging port identification (CDP/DCP), 3A current-limit switching, status signaling, and fault protection in real hardware. It is not a standalone IC but a ready-to-use reference design with MP2499M and MP5030D pre-mounted.

How do I configure the board for Dedicated Charging Port (DCP) mode?

To enable DCP mode: leave JP2 open, float the MODE pin (remove JP1 short), and replace R9 and R10 with 0Ω resistors as specified in the Quick Start Guide. Do not connect the USB_Plug header; instead, use only the Type-A USB port for downstream device charging.

Does the board include a DC/DC converter? If so, what is its role?

Yes - U1 is the MP2499M synchronous step-down converter in QFN-13 (2.5mm × 3mm). It converts the 12V input to 5V, supplying clean, regulated power to the MP5030D (U2) and the USB port, ensuring stable operation during high-current charging tests.

What are the key test points and signals accessible on the board?

Accessible signals include VIN (12V input), VOUT (5V output), EN (enable control), STATUS (open-drain fault/status), D+ and D− (USB data lines), and MODE (mode selection). Test points are labeled on silkscreen per Figures 1–4 in the schematic documentation.

Is the EV5030D-QH-00A RoHS-compliant and lead-free?

Yes - all components on the EV5030D-QH-00A, including MP5030D and MP2499M, are lead-free, halogen-free, and compliant with the RoHS directive, consistent with MPS's green manufacturing policy confirmed on their official quality assurance page.
