Product details
Overview
MPQ5031GRE-0015-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified USB Type-C power delivery controller for single-port DFP (downstream-facing port) source applications. It implements full USB PD3.0 and PPS protocols, supports up to 100W output, integrates BMC physical layer, protocol engine, and policy engine, and features dual NTC thermal monitoring pins for automotive-grade thermal safety in vehicle-mounted USB charging ports.
For engineers reviewing the MPQ5031GRE-0015-AEC1-Z datasheet, MPQ5031GRE-0015-AEC1-Z pinout, MPQ5031GRE-0015-AEC1-Z application, or MPQ5031GRE-0015-AEC1-Z equivalent, this device delivers certified 100W PPS operation with integrated VCONN switching, high-voltage CC/DP/DM I/O protection, and I2C-configurable PDO lists - critical for automotive infotainment head units, center console chargers, and USB PD hubs requiring AEC-Q100 compliance and robust legacy charging support (QC3.0, FCP, BC1.2).
Technical Context
The MPQ5031GRE-0015-AEC1-Z embeds a complete USB PD3.0 stack including BMC transceiver, protocol layer, and policy engine - enabling autonomous negotiation of fixed, variable, and programmable power supply (PPS) contracts without host MCU intervention. Its dual NTC inputs and battery-low detection logic enable load-shedding during low-voltage conditions common in automotive stop-start systems.
It operates as a dedicated DFP-only controller with integrated 1.8V VDD LDO, high-voltage (24V-tolerant) CC1/CC2/DP/DM pins, and VDRV gate driver for external N-channel MOSFET VBUS isolation. The I2C_MODE pin selects master/slave operation, and GPIO7 provides EN_OFF timer control up to 120 minutes - essential for unattended vehicle charging scenarios.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD source controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Single-port PD3.0 controller with integrated 5V LDO; no native PPS support; requires external VCONN switch; lower max power (60W) | Targeted at cost-sensitive consumer docks; lacks AEC-Q100 qualification and automotive thermal monitoring features | Select when PPS is not required and automotive qualification is unnecessary; verify external VCONN circuit design. |
| TUSB8041A | USB 3.0 hub controller with embedded PD3.0 support; includes four USB 3.0 ports; higher integration but no standalone DFP mode | Designed for multi-port USB hubs with host-side PD negotiation; not suitable for single-port source-only automotive applications | Choose only if expanding to multi-port architecture with host-controlled PD negotiation; incompatible with DFP-only use case. |

FAQ
What USB PD profiles does MPQ5031GRE-0015-AEC1-Z support?
MPQ5031GRE-0015-AEC1-Z supports all USB PD3.0 fixed, variable, and programmable power supply (PPS) profiles up to 20V/5A (100W). It has passed official USB-IF PPS certification with MPQ4214 (TID: 2316) and supports dynamic PDO list configuration via I2C - enabling custom voltage/current combinations for fast-charging laptops and smartphones.
How does the device handle low-battery conditions in automotive systems?
The MPQ5031GRE-0015-AEC1-Z monitors VBATT via GPIO4 and triggers automatic PDO capability reduction when battery voltage falls below 11.2V (typical). This prevents overloading the vehicle's electrical system during stop-start operation or low-state-of-charge conditions - a feature validated in automotive-grade thermal and voltage stress testing.
Can MPQ5031GRE-0015-AEC1-Z operate without an external MCU?
Yes. MPQ5031GRE-0015-AEC1-Z integrates a complete USB PD3.0 stack - including BMC PHY, protocol layer, and policy engine - allowing fully autonomous PD negotiation, legacy charging detection, and VBUS control without host processor intervention. I2C is optional for advanced configuration or status monitoring.
What is the purpose of the two NTC pins?
The NTC and NTC2 pins (pins 13 and 18) accept external thermistors to monitor temperature at critical locations - such as the USB Type-C receptacle and adjacent PCB traces. When threshold voltages are exceeded (e.g., 9.1% VCC at 100°C), the device initiates load shedding to prevent thermal damage - a key requirement for AEC-Q100 Grade 1 qualification.
Does MPQ5031GRE-0015-AEC1-Z support USB 2.0 data communication?
No. MPQ5031GRE-0015-AEC1-Z uses DP/DM pins solely for legacy charging protocol detection (BC1.2, QC3.0, FCP) and does not implement USB 2.0 data packet transmission or enumeration. It is a power delivery controller only - data path functionality must be implemented separately via a USB 2.0 transceiver or hub IC.
What package variant is used for MPQ5031GRE-0015-AEC1-Z?
MPQ5031GRE-0015-AEC1-Z uses the QFN-20 (4mm × 4mm) package with wettable flanks, as confirmed by the ordering table and package drawing in the datasheet. This package supports AOI-compatible solder joints and meets automotive thermal dissipation requirements (θJA = 60°C/W on 4-layer JEDEC board).
Is VCONN power generation integrated?
Yes. MPQ5031GRE-0015-AEC1-Z includes an integrated VCONN power switch capable of delivering up to 100mW. It activates automatically upon detection of RA (pull-down resistor <1.2kΩ on CC line) and powers active cables and e-markers - eliminating the need for external VCONN regulators or discrete MOSFETs.
