Product details
Overview
MP5031GRE-00A3-P from Monolithic Power Systems is a USB Type-C port controller IC implementing full USB PD 3.0 and PPS protocol stacks, integrated BMC PHY, policy engine, and DFP-side power management for single-port charging applications. It supports five configurable PDOs up to 100W, load-shedding via NTC/low-battery detection, and backward compatibility with QC3.0, FCP, BC1.2, Apple Divider 3, and 1.2V/1.2V modes. Used in automotive and multi-port wall chargers requiring robust VBUS control and thermal-aware power budgeting.
For engineers reviewing the MP5031GRE-00A3-P datasheet, MP5031GRE-00A3-P pinout, MP5031GRE-00A3-P application, or MP5031GRE-00A3-P equivalent, this page delivers verified technical context, QFN-20 pin-level design meaning, real-world USB PD 3.0 + PPS implementation constraints, and validated alternative selection guidance for DFP port controller deployment.
Technical Context
The MP5031GRE-00A3-P integrates a complete USB PD 3.0 stack-including physical layer (BMC transceiver), protocol layer, and policy engine-within a single die, eliminating external MCU dependency for PD negotiation. Its dual-role CC1/CC2 interface handles plug orientation detection, VCONN sourcing (≤100mW), and VBUS_P sensing/discharge with high-voltage tolerance (−0.3V to +24V).
It implements load-shedding through two independent NTC inputs and GPIO-based low-battery detection (VBATT_LOW falling threshold = 1.07–1.17V), enabling dynamic PDO capacity reduction when input voltage drops. The I²C master/slave interface configures all five PDOs, selects slave devices (e.g., DC/DC converters), and enables protection modes without firmware intervention.

FAQ
What USB PD specifications does MP5031GRE-00A3-P support?
MP5031GRE-00A3-P fully supports USB PD 3.0 specification including structured vendor-defined messages (VDMs), fast role swap (FRS), and programmable power supply (PPS) with 20mV/50mA resolution. It is USB-IF certified for both 60W and 100W PPS operation and maintains backward compatibility with USB Type-C 2.0 cable detection and BC1.2 charging protocols.
How is the five-PDO configuration stored and updated?
The five-PDO configuration is stored in one-time-programmable (OTP) memory during manufacturing, with default settings defined by the "-00A3" suffix. Runtime updates are supported via I²C interface using CTL registers; changes persist until next power cycle unless written to OTP. Configuration includes voltage/current limits, fixed/variable/APDO types, and priority ordering.
Does MP5031GRE-00A3-P require an external microcontroller?
No. MP5031GRE-00A3-P integrates a complete USB PD 3.0 stack-including BMC PHY, protocol layer, and policy engine-enabling autonomous PD negotiation without external MCU. An MCU is optional only for advanced system-level coordination (e.g., multi-port power sharing or GUI-based configuration), not for basic PD operation.
What protection features are implemented on-chip?
On-chip protections include VCC under-voltage lockout (4.3V rising threshold), VBUS_P UVLO (2.97V), thermal shutdown (150°C with 20°C hysteresis), CC/DP/DM overvoltage tolerance (±24V), and integrated VCONN current limiting (100mW max). External MOSFET gate drive (VDRV) enables controlled VBUS isolation during faults.
Can MP5031GRE-00A3-P support dual-role port (DRP) functionality?
No. MP5031GRE-00A3-P is strictly a downward-facing port (DFP) controller. It lacks hardware support for UFP (sink) operation or DRP toggling. For DRP applications, MPS recommends pairing it with complementary sink-side controllers like MP547x series or using dedicated DRP ICs such as STUSB4760.
What is the purpose of the I2C_MODE pin?
The I2C_MODE pin configures master/slave I²C operation: pulled low or floating → master mode (MP5031 drives SCL/SDA); pulled high → slave mode (MP5031 responds to external master). In slave mode, GPIO5/GPIO6 functions are disabled, and SDA/SCL become dedicated slave interface pins with 1MΩ internal pull-down on I2C_MODE.
Is the QFN-20 package RoHS and halogen-free?
Yes. MP5031GRE-00A3-P meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. All MPS products are lead-free, and the wettable flanks facilitate automated optical inspection (AOI) and improve solder joint reliability in high-volume manufacturing.
