Overview
MPQ4242GVE-0015-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated USB PD 3.0 sourcing solution with 4-switch buck-boost converter, supporting 4.8V–36V input, 3.3V–22.5V output, and up to 5A continuous current. It integrates PD controller, CC logic, I²C interface, and dual-port power sharing for automotive USB-C charging ports.
For engineers reviewing the MPQ4242GVE-0015-AEC1-Z datasheet, MPQ4242GVE-0015-AEC1-Z pinout, MPQ4242GVE-0015-AEC1-Z application, or MPQ4242GVE-0015-AEC1-Z equivalent, this device delivers verified PPS compliance, BC1.2/DCP/QC3.0/FCP protocol support, ±5% CC current limit accuracy, configurable 250/420kHz switching, and wettable-flank QFN-22 packaging for automotive-grade reflow inspection.
Technical Context
The MPQ4242 implements a synchronous 4-switch buck-boost topology with internal high-side and low-side MOSFETs (RDS(on) = 16.3mΩ/15mΩ and 41.5mΩ/15.3mΩ), enabling seamless transition between buck, boost, and buck-boost modes across its full 3.3V–22.5V VOUT range. Its embedded USB PD 3.0 controller supports seven PDOs, Programmable Power Supply (PPS), and hardware-based state machine execution without host MCU intervention.
It features dual CC channel detection (CC1/CC2), integrated VCONN power (100mW/1W selectable), DP/DM data-line handshaking for legacy charging protocols, and real-time thermal management via NTC/NTC2 inputs. Fault handling includes hiccup-mode current limiting, OVP (24–26V absolute), VIN UVLO (4.3V rising), and thermal shutdown at 175°C with 20°C hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD sourcing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4242GVE-0000-AEC1-Z | Default 60W OTP-configured version; one-time programmable register settings preloaded for 5V/9V/15V/20V PDOs. | Fixed PDO list; no field reconfiguration after programming. | Select when production volume justifies OTP customization and fixed power profile suffices. |
| MPQ4242GVE-0001-AEC1-Z | 45W standard version; non-reprogrammable OTP; optimized for lower-power automotive accessories. | Limited to four PDOs (5V/9V/12V/15V); reduced thermal design margin vs. -0015 variant. | Choose for cost-sensitive rear-seat or low-power modules where 60W headroom is unnecessary. |
Compared with MPQ4242GVE-0015-AEC1-Z, the -0000 variant offers factory-programmed flexibility for high-volume OEMs, while the -0001 variant trades configurability for lower unit cost and simplified qualification-making the -0015 ideal for development and mid-volume programs requiring field-tunable PDOs.

FAQ
What USB PD protocols does MPQ4242GVE-0015-AEC1-Z support?
It supports USB PD 3.0 with Programmable Power Supply (PPS), backward compatibility with PD 2.0, and legacy charging protocols including BC1.2 DCP, 3A divider mode, 1.2V/1.2V mode, Qualcomm QC 2.0/3.0, and Huawei FCP-all implemented in hardware without firmware dependency.
How is output voltage accuracy maintained across load and temperature?
VOUT regulation holds ±1.5% over full load (0–5A) and temperature (−40°C to +125°C) due to precision internal references, on-die trimming, and optional line-drop compensation that injects up to 600mV correction at 3A to offset PCB IR loss.
Can MPQ4242GVE-0015-AEC1-Z drive external MOSFETs?
Yes-it provides dedicated HS_G (high-side gate drive) and GPIO1 (low-side gate drive) outputs to control external N-channel MOSFETs, enabling current scaling beyond 5A and thermal distribution across multiple packages in high-power applications.
What thermal protection mechanisms are built in?
It includes junction thermal shutdown at 175°C with 20°C hysteresis, NTC/NTC2 thermal sense inputs for external temperature monitoring, and configurable PD power management that reduces delivered power during low battery voltage or elevated temperature conditions.
Is I²C configuration required for basic USB-C operation?
No-default OTP settings enable immediate USB-C source functionality (5V/9V/15V/20V PDOs, 250kHz switching, standard fault responses). I²C is optional for advanced tuning: custom PDOs, LED PWM, LDC gain, PS_PDP_THD, and NTC hysteresis.
How does dual-port power sharing work between two MPQ4242 ICs?
Hardware logic uses POWER_SHARE1 (active-low) and POWER_SHARE2 (active-high) pins to coordinate real-time power allocation. When one port reaches its share threshold, the other dynamically adjusts its PDO to maintain total system power within defined limits-no software or host MCU needed.
What is the significance of "-0015" in the part number?
The "-0015" suffix indicates a unique OTP configuration code defining register values for PDO list, switching frequency, line drop compensation, and fault thresholds. Unlike -0000 (60W default) or -0001 (45W standard), -0015 is a customer-specific configuration created with MPS FAE support.
