Used in automotive USB charging ports and PD-enabled hubs.

For engineers reviewing the MPQ5031GRE-0013-AEC1-Z datasheet, MPQ5031GRE-0013-AEC1-Z pinout, MPQ5031GRE-0013-AEC1-Z application, or MPQ5031GRE-0013-AEC1-Z equivalent, key selection criteria include AEC-Q100 qualification, 100W PPS support with TID 2316 certification, QFN-20 wettable flank package, low 100µA standby IQ, and integrated VCONN switch with high-voltage CC/DP/DM I/O protection.

Technical Context

The MPQ5031GRE-0013-AEC1-Z implements a full USB PD 3.0 stack-including BMC transceiver, protocol layer, and policy engine-within a single IC, eliminating need for external MCU firmware. Its dual-mode legacy charging detection (BC1.2 CDP + DCP auto-detection across divider, 1.2V/1.2V, QC3.0, FCP) operates without host intervention and coexists with PD negotiation.

It supports dynamic power sharing between two USB PD ports via GPIO2-based load shedding, enables battery-low-triggered PDO reduction using VBATT sensing on GPIO4, and provides isolated VBUS control through VDRV-driven external N-channel MOSFET. High-voltage CC1/CC2/DP/DM pins withstand short-to-battery and short-to-VBUS events per automotive requirements.

FAQ

What USB PD profiles does MPQ5031GRE-0013-AEC1-Z support out-of-the-box?

MPQ5031GRE-0013-AEC1-Z supports USB PD 3.0 with Programmable Power Supply (PPS), plus backward-compatible legacy protocols: BC1.2 DCP/CDP, QC3.0 Class A, Huawei FCP, Apple 3A divider, and 1.2V/1.2V mode. All are implemented in hardware with no firmware required - PDO list is configurable via I²C registers or OTP settings.

How does the MPQ5031 handle thermal protection in automotive environments?

The device uses two dedicated NTC input pins (NTC and NTC2) to monitor temperature at critical locations like the Type-C receptacle or PCB hotspots. When sensed voltage crosses the trip threshold (e.g., 9.1% of VCC at 100°C with 47kΩ/4.72kΩ divider), it triggers automatic load shedding or PDO reduction - a hardware-level response independent of I²C host intervention.

Is MPQ5031GRE-0013-AEC1-Z pin-compatible with other MPQ5031 variants?

Yes - all MPQ5031 variants (e.g., -0001-AEC1, -0015-AEC1) share identical QFN-20 pinout and electrical characteristics. The suffix "-0013" denotes a specific OTP configuration (e.g., pre-programmed PDO set, GPIO defaults), but mechanical and signal-level compatibility is maintained across the family.

What is the role of the VDRV pin, and what MOSFET parameters are recommended?

VDRV is a gate driver output controlling an external N-channel MOSFET in the VBUS power path. It delivers ~4.85V drive voltage relative to VBUS_P and supports fast turn-on/turn-off. MPS recommends logic-level MOSFETs with R_DS(on) < 10mΩ and Q_g < 20nC (e.g., SQJQ910EL) to ensure reliable isolation during detach and low conduction loss at 5A.

Does MPQ5031GRE-0013-AEC1-Z support USB-C audio adapter accessory mode?

No - MPQ5031GRE-0013-AEC1-Z is a DFP (source-only) controller with no UFP (sink) or DRP (dual-role) capability. It does not implement audio adapter accessory mode (which requires UFP-side CC logic and analog audio switch control), nor does it support USB-C Alt Mode display protocols.

How is VCONN powered, and what protection does it include?

VCONN is supplied internally from VCC via an integrated high-voltage switch, delivering up to 100mW. Activation requires detection of RA (≤1.2kΩ pull-down on CC) - preventing accidental activation. The switch includes overcurrent and thermal foldback, and VCONN is automatically disabled during VBUS faults or thermal shutdown.

Can MPQ5031GRE-0013-AEC1-Z operate without an external MCU?

Yes - it functions autonomously for basic DFP operation: legacy charging detection, PD negotiation, VBUS control, and thermal response all execute in hardware. An MCU is only required for advanced customization (e.g., dynamic PDO updates, multi-port coordination, or GUI-based configuration via I²C).
