Monolithic Power Systems Inc. MP5030CGQH-P

Overview

MP5030CGQH-P 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 operates across 2.7–14V input, delivers 5V output with programmable line-drop compensation up to 350mV at 2.4A, and features 32mΩ R_DS(ON), hiccup OCP, input OVP (115% threshold), and thermal shutdown at 160°C - deployed in automotive USB car chargers and industrial docking stations.

For engineers reviewing the MP5030CGQH-P datasheet, MP5030CGQH-P pinout, MP5030CGQH-P application, or MP5030CGQH-P equivalent, key selection criteria include QC3.0 voltage-slewing behavior (5V→9V/9V→12V transitions), CDP mode data-path integrity (DP_OUT/DM_OUT isolation), ADJ-sink-based 5V regulation accuracy (±1% at 25°C), and ILIM-resistor programmability for 3.13–3.57A current limit tolerance.

Technical Context

The MP5030CGQH-P implements dual-stage UVLO (3.0V and 3.9V thresholds) with 4–6ms startup delay and internal soft-start (290µs). Its MODE pin selects among three functional states: high (DCP+QC3.0), float (DCP-only), or low (CDP with DP/DM pass-through), each enabling distinct USB handshaking protocols without firmware intervention.

Line drop compensation is linearly proportional to load current via ADJ pin sinking up to 500µA; at 2.4A, it injects +220–350mV into upstream DC/DC feedback to maintain 5V at load. Input OVP uses dynamic thresholding (110–120% of VIN) with 10µs deglitch and automatic discharge path activation (72Ω) during high-to-low voltage transitions.

Key Specifications

Pinout & Package

MP5030CGQH-P is housed in a thermally enhanced QFN-10 package (1.5mm × 2mm, 0.5mm height) with exposed thermal pad. Pin 1 is marked by top-side index area; recommended land pattern includes 9 solder mask defined pads plus central thermal pad connected to internal GND plane via ≥4 vias.

Compared with MP5030CGQH-P, MP5031CGQH-P adds USB-C PD capability but removes CDP data routing, while TUSB211IRWBR provides signal conditioning only and cannot substitute for integrated power management - making MP5030CGQH-P uniquely suited for USB-A CDP/DCP/QC3.0 consolidation.

FAQ

What is the maximum allowable input voltage for MP5030CGQH-P?

The absolute maximum input voltage is +16V, but recommended operating conditions specify up to +14V. Exceeding 14V risks triggering input OVP at 115% of VIN (e.g., 12.65V at 11V input), causing immediate shutdown and discharge activation. Sustained operation above 14V may degrade long-term reliability despite surviving short transients.

How does the ADJ pin enable line drop compensation?

The ADJ pin sinks a controlled current (up to 500µA) from the upstream DC/DC converter's FB node. As load current increases, the sink current rises linearly, forcing the upstream regulator to raise its output voltage - adding +220mV at 2.4A to offset trace resistance losses and maintain 5V at the USB connector.

Can MP5030CGQH-P operate in CDP mode with USB 2.0 high-speed data?

Yes - in CDP mode (MODE = low), DP and DM signals are routed directly to DP_OUT and DM_OUT pins with 500MHz bandwidth and <5.8ms deglitch timing, preserving USB 2.0 high-speed (480Mbps) eye diagram integrity per USB-IF test specifications.

What is the purpose of the ILIM resistor, and how is its value selected?

The ILIM resistor sets the current limit threshold between 2.5A and 4.3A. For 3.35A nominal, use 1.5kΩ (per datasheet curve on page 6). The resistor must be 1% tolerance metal-film; deviation beyond ±0.5% causes >±50mA error in trip point, risking USB-IF 3A compliance failure.

Does MP5030CGQH-P support USB Battery Charging Specification v1.2?

Yes - it fully supports BC1.2 DCP modes including divider mode, 1.2V/1.2V mode, and Chinese Telecommunications Industry Standard YD/T 1591-2009. It detects DCP by measuring DP/DM short resistance (<50Ω) and applies appropriate voltage profiles without host MCU involvement.

How does thermal shutdown behave during sustained overload?

At junction temperature ≥160°C, the device shuts down completely. Recovery occurs only after die temperature falls below 125°C (160°C − 35°C hysteresis). During hiccup OCP, thermal shutdown acts as secondary protection if repeated fault cycles cause cumulative heating beyond safe limits.

Is MP5030CGQH-P compatible with both buck and boost upstream converters?

Yes - its wide 2.7–14V input range and ADJ-based regulation interface work with buck, boost, and AC/DC converters. Critical requirement: upstream converter's current limit must exceed MP5030CGQH-P's programmed ILIM value to avoid premature foldback.
