Product details
Overview
MPQ7930GUTE-0000-AEC1-P from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified PMIC for automotive safety-critical systems, integrating six synchronous buck converters (two 4A, two 3A, two 1A) with 2MHz fixed-frequency PWM control, PMBus interface with PEC, and independent enable sequencing. It operates from 2.7V–5.5V input and supports dynamic voltage scaling across all channels in ADAS domain controllers.
For engineers reviewing the MPQ7930GUTE-0000-AEC1-P datasheet, MPQ7930GUTE-0000-AEC1-P pinout, MPQ7930GUTE-0000-AEC1-P application, or MPQ7930GUTE-0000-AEC1-P equivalent, this device delivers configurable multi-phase power delivery, MOTP-based configuration storage, thermal warning/shutdown protection, and wettable-flank TQFN-32 packaging for automotive-grade reliability and solder-joint inspection.
Technical Context
The MPQ7930 implements a six-channel synchronous buck architecture with configurable dual-phase operation (e.g., Bucks 1/3/6 phase-shifted 180°, Bucks 2/4/5 phase-shifted 180°), enabling optimized EMI reduction via frequency spread spectrum (FSS) and precise transient response through 60ns minimum on/off times. Each channel features independent soft-start slew rate control stored in MOTP memory.
Its PMBus v1.3-compliant interface supports packet error checking (PEC), multi-page OTP register programming, and real-time telemetry including voltage, current, temperature, and fault status. Protection logic includes hiccup-mode OCP/UVP/OVP, thermal shutdown at 155–185°C, and UVLO with 180mV hysteresis on VIN.

Pinout & Package
TQFN-32 (5mm × 5mm) package with wettable flank terminals, rated MSL Level 1, designed for high-density automotive PCB layouts requiring thermal performance (θJA = 31.7°C/W on JEDEC 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1–VIN4 | Independent input supply rails | Four isolated 2.7–5.5V inputs feeding internal control logic and power switches; must be connected via copper pour, not separated. |
| SW1–SW6 | Buck switch nodes | High-side/low-side FET connection points; require external inductors and must be floated or pulled to GND if unused. |
| VOUT1–VOUT6 | Feedback inputs | Resistive divider inputs for output voltage regulation; each supports 0.20625V–3.6V range with ±1.5% accuracy. |
| EN1–EN6 | Individual buck enables | Logic-controlled sequencing inputs (1.4V threshold); internal pull-down resistors (1.05–1.95MΩ) enable flexible power-up timing. |
| SCL/SDA | PMBus interface | Open-drain serial bus pins requiring external pull-ups; support 1MHz clock, PEC, and multi-page OTP read/write. |
| ALERT/PG | Fault and power-good indicators | Open-drain outputs: ALERT asserts low on any fault; PG goes high only when all six outputs are within ±4.5%/−3.5% of nominal. |
| VCC/AGND/PGNDx | Bias supply and ground references | VCC = internal 3.35V LDO (10µF decoupling required); AGND is isolated analog reference; PGND pins are internally tied but require separate PCB pours. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP FS26 | ARM Cortex-M0+ safety monitor co-processor; 4 buck channels (max 3A); no PMBus, uses SPI | Targeted at ASIL-D safety islands with embedded diagnostics; lacks DVS and MOTP configurability | Select when functional safety certification (ISO 26262) and lockstep monitoring outweigh flexibility and telemetry needs. |
| Renesas ISL78600 | 5 buck channels (max 3A); 1.2MHz max fSW; no FSS; I²C-only interface; no wettable flanks | Optimized for cost-sensitive body electronics; lower EMI suppression capability and no AEC-Q100 Grade 1 extended temp support | Select for non-safety-critical interior modules where thermal derating above 125°C is not required. |
Compared with FS26 and ISL78600, MPQ7930GUTE-0000-AEC1-P uniquely combines six configurable bucks, 2MHz FSS switching, PMBus telemetry, and wettable-flank packaging - making it the only option supporting full ASIL-B power sequencing and EMI-constrained ADAS domain controller designs without external supervision.

FAQ
What is the purpose of the MOTP memory in MPQ7930GUTE-0000-AEC1-P?
The multi-page one-time programmable (MOTP) memory stores critical configuration data including default output voltages, power-up sequencing order, soft-start slew rates, and protection thresholds. This eliminates the need for external configuration EEPROM and ensures deterministic, repeatable startup behavior across automotive production units without host intervention.
How does the 180° phase shift between buck channels reduce EMI?
The MPQ7930 groups Buck 1/3/6 and Buck 2/4/5 with 180° phase offset, causing their switching current harmonics to cancel at key frequencies. Combined with 15% frequency spread spectrum modulation, this reduces peak conducted and radiated emissions by up to 12dB - directly easing CISPR 25 Class 5 compliance in compact ADAS modules.
Can MPQ7930GUTE-0000-AEC1-P support dual-phase operation for higher-current rails?
Yes - the device allows pairing of any two bucks (e.g., Buck 1 + Buck 2) into a dual-phase configuration via PMBus register settings. This doubles effective current capability (e.g., 4A + 4A = 8A) while halving input/output ripple current and improving thermal distribution across the die and PCB.
What is the significance of the wettable flank package for automotive use?
The TQFN-32 wettable flank design exposes solderable sidewalls, enabling automated X-ray and optical inspection of solder joint quality. This is mandated by IATF 16949 for zero-defect manufacturing in safety-critical automotive electronics, ensuring mechanical reliability under thermal cycling and vibration stress.
Does MPQ7930GUTE-0000-AEC1-P provide real-time telemetry via PMBus?
Yes - the PMBus interface supports readback of real-time parameters including individual channel output voltage, temperature (die and external via external NTC), input/output current (via sense resistor configuration), fault status (OVP/UVP/OCP/thermal), and power-good status - enabling closed-loop health monitoring in ISO 26262-compliant systems.
How is thermal protection implemented beyond shutdown?
In addition to thermal shutdown (155–185°C), the MPQ7930 includes a programmable thermal warning threshold (125–155°C) that asserts the ALERT pin early, allowing host firmware to throttle loads or initiate cooling before catastrophic failure - a key requirement for ASIL-B thermal management strategies.
What are the voltage accuracy specifications across temperature and input conditions?
VOUT accuracy is ±1.5% over −40°C to +150°C junction temperature and across 2.7V–5.5V input voltage, verified at 600mV and 1.8V nominal outputs. This stability is maintained via on-chip trimming and feedback amplifier design, meeting stringent requirements for SoC core rail regulation.
