Product details
Overview
MP5031GRE-00A3-Z 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 control logic. It supports up to 100W (20V/5A) delivery with five configurable PDOs, load-shedding via NTC/low-battery detection, and VBUS isolation using external N-MOSFETs. Designed for multi-port wall chargers and automotive DFP applications requiring backward compatibility with QC3.0, FCP, BC1.2, Apple Divider 3, and 1.2V/1.2V modes.
For engineers reviewing the MP5031GRE-00A3-Z datasheet, MP5031GRE-00A3-Z pinout, MP5031GRE-00A3-Z application, or MP5031GRE-00A3-Z equivalent, key selection criteria include its QFN-20 wettable-flank package, I²C-configurable PDO list and charging protocols, thermal-sense-enabled load-shedding, high-voltage CC/DP/DM pins rated to +24V, and integrated VCONN MOSFET driver supporting 100mW cable power.
Technical Context
The MP5031GRE-00A3-Z integrates a complete USB PD 3.0 stack - physical layer (BMC transceiver), protocol layer, and policy engine - enabling autonomous negotiation of voltage/current profiles including PPS (3.3–21V ±20mV). Its dual-role CC1/CC2 interface detects UFP attachment, manages VCONN sourcing, and handles plug orientation detection via POL output.
It implements hardware-based legacy charging auto-detection across BC1.2, Apple Divider 3, 1.2V/1.2V, QC3.0, and FCP without host intervention, while retaining full I²C configurability for GPIO mapping, protection thresholds, and PDO selection. Load-shedding is triggered by either NTC thermistor input or low-battery detection on VBATT, dynamically scaling PDO capacity in real time.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Lacks integrated VCONN driver and NTC-based load-shedding; requires external MOSFET and thermal sensor | Targeted at cost-sensitive single-port chargers without automotive thermal constraints | Select when design uses discrete VCONN regulation and does not require automatic thermal derating |
| TUSB8041IRGZT | USB 3.0 hub controller with basic PD support only; no PPS, no legacy charging auto-detect, no GPIO flexibility | Used in host-side USB hubs where PD is secondary to data routing | Select only if primary function is USB 3.0 data switching and PD is limited to fixed 5V/3A |
Compared with STUSB4500QTR and TUSB8041IRGZT, MP5031GRE-00A3-Z delivers higher integration (integrated VCONN, BMC PHY, policy engine), broader legacy protocol coverage, and hardware-based thermal/load-shedding - making it optimal for space-constrained, multi-protocol DFP applications demanding reliability and minimal BOM count.

FAQ
What USB PD specifications does MP5031GRE-00A3-Z support?
The MP5031GRE-00A3-Z fully complies with USB PD 3.0 and supports Programmable Power Supply (PPS) profiles from 3.3V to 21V with ±20mV regulation. It implements the complete BMC physical layer, protocol layer, and policy engine - enabling autonomous negotiation of up to five configurable PDOs without external firmware.
Does MP5031GRE-00A3-Z require an external microcontroller?
No. The MP5031GRE-00A3-Z integrates all core USB PD functionality - including BMC transceiver, protocol stack, and policy engine - in a single chip. While I²C allows optional host configuration, legacy charging auto-detection (BC1.2, QC3.0, FCP) operates autonomously via hardware state machines.
How does load-shedding work on MP5031GRE-00A3-Z?
Load-shedding is triggered by either NTC thermistor input (pin 13) or low-battery detection on GPIO4. When temperature exceeds programmed threshold or VBATT falls below 1.12V, the IC automatically reduces PDO capacity - e.g., stepping down from 20V/5A to 9V/2A - to maintain system stability without interrupting charging.
What is the purpose of the VDRV pin?
VDRV (pin 19) is a dedicated gate driver output for controlling an external N-channel MOSFET in the VBUS power path. It turns the MOSFET on during UFP attachment to enable power delivery and off during detachment or fault conditions to isolate VBUS - ensuring safe hot-plug operation and short-circuit protection.
Can MP5031GRE-00A3-Z support dual USB-C ports?
Yes - the MP5031GRE-00A3-Z supports power-sharing between two DFP ports via GPIO2. When used in dual-port designs, one MP5031 can monitor the other's power demand and dynamically adjust its own PDO capacity to stay within total system power limits - enabling intelligent multi-port power budgeting.
Is VCONN power integrated or external?
VCONN power is fully integrated: the MP5031GRE-00A3-Z includes an on-chip high-voltage MOSFET capable of delivering up to 100mW to active USB-C cables. No external regulator or switch is required - simplifying layout and reducing bill-of-materials cost.
What package variant is MP5031GRE-00A3-Z?
MP5031GRE-00A3-Z uses the QFN-20 (4mm × 4mm) package with wettable flanks, optimized for thermal performance and automated optical inspection. The "-Z" suffix indicates tape-and-reel packaging; "GRE" denotes green (RoHS/halogen-free) compliance per MPS quality standards.
