Product details

Overview

MPQ7930GUTE-0000-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified power management IC (PMIC) for automotive safety-critical systems, integrating six synchronous buck converters-two rated at 4A, two at 3A, and two at 1A-with 2MHz fixed-frequency PWM control, PMBus interface with PEC, and multi-page one-time programmable (MOTP) memory. It supports dynamic voltage scaling and independent enable sequencing for ADAS domain controllers.

For engineers reviewing the MPQ7930GUTE-0000-AEC1-Z datasheet, MPQ7930GUTE-0000-AEC1-Z pinout, MPQ7930GUTE-0000-AEC1-Z application, or MPQ7930GUTE-0000-AEC1-Z equivalent, this device delivers configurable multi-phase power delivery, thermal warning/shutdown protection, spread-spectrum EMI reduction, and wettable-flank TQFN-32 packaging for automotive-grade reliability and solder-joint inspection.

Technical Context

The MPQ7930 implements a six-channel PMIC architecture with independent buck converter control logic, where Buck 1–4 use lower R_DS(on) MOSFETs (30–90 mΩ HS / 16–45 mΩ LS) for higher-current rails, while Buck 5–6 feature higher R_DS(on) (130–250 mΩ HS) optimized for low-noise, low-power auxiliary rails. All channels support programmable slew rates (2.5–40 mV/µs), soft-start, and hiccup-mode OCP/UVP/OVP.

PMBus v1.3 compliance enables real-time telemetry (voltage, current, temperature), fault logging, and OTP-based configuration persistence across power cycles. Phase interleaving (180° shift between Buck 1/3/6 and Buck 2/4/5) reduces input ripple, while frequency spread spectrum (±15% modulation at 9 kHz) suppresses peak EMI without compromising transient response.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.7V to 5.5V - Supports wide automotive battery range including cold-crank (≥2.7V) and load-dump transients (≤5.5V).
Output Voltage Range	0.20625V to 3.6V - Programmable via MOTP or PMBus; covers core logic (0.8V), I/O (1.8V/3.3V), and analog rails.

Pinout & Package

TQFN-32 (5mm × 5mm) package with wettable flanks, exposed thermal pad, and 0.5mm pitch. Pin 1 marked by dot; top-side marking includes MPS prefix, year/week code, part number, lot ID, and "E" for wettable flank.

Pin/Terminal	Circuit Role	Design Meaning
1, 5, 9, 21 (PGNDx)	Power ground	Internally connected PGND nodes; require low-inductance PCB pour to minimize switching noise coupling.
3, 7, 19, 23 (VINx)	Input supply	Independent VIN pins per buck group; must be tied externally with copper pours-no internal connection.
2, 4, 6, 8, 20, 22 (SWx)	Switch node	High-frequency switching outputs; each requires dedicated LC filter and Kelvin feedback routing.
10, 11, 18, 24, 31, 32 (VOUTx)	Feedback input	Resistive divider inputs for VOUT regulation; 12kΩ leakage ensures stable DC bias under light/no load.
12, 13, 17, 26, 29, 30 (ENx)	Enable control	Independent logic-enable inputs with 1.3V/1.4V thresholds and internal pull-downs (1.05–1.95MΩ) for flexible sequencing.
14 (SCL), 15 (SDA)	PMBus interface	Open-drain buses requiring external pull-ups; support hot-plug detection and packet error checking (PEC).
16 (ALERT), 25 (PG)	Fault signaling	Open-drain outputs: ALERT asserts low on any fault; PG goes high only when all six outputs are within ±4.5%/−3.5% tolerance.
27 (AGND), 28 (VCC)	Analog reference & bias	AGND is isolated from PGND; VCC is internal 3.35V LDO-requires 10µF ceramic cap placed <1mm from pin.

Key Features

Feature	Design Value
Configurable multi-phase operation	Supports 3 dual-phase (e.g., 2×4A, 2×3A, 2×1A) or 6 independent single-phase configurations via MOTP register settings.
Dynamic voltage scaling (DVS)	Real-time VOUT adjustment during operation via PMBus WRITE_VOUT command-enables processor DVFS for power/performance optimization.
Spread-spectrum EMI reduction	±15% frequency modulation at 9 kHz lowers peak radiated emissions without impacting loop stability or transient response.
Independent soft-start control	Slew rate programmable per channel (1.25–20 mV/µs start-up; 2.5–40 mV/µs dynamic) to prevent inrush current and rail overshoot.
AEC-Q100 Grade 1 qualification	Rated for −40°C to +150°C junction temperature-validated for ADAS ECU deployment in engine bay and radar modules.

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	Integrated CAN FD transceiver + watchdog; no PMBus; uses SPI instead of PMBus; 4 buck channels (max 3A each)	Better suited for gateway ECUs needing embedded communication; lacks DVS and multi-page OTP configurability	Select when CAN FD interface and functional safety co-processor features outweigh need for sixth rail and fine-grained telemetry.
Renesas ISL78600	5 buck channels (3×3A, 2×2A); no spread-spectrum; 1.2MHz max fSW; no MOTP memory-configuration stored in external EEPROM	Lower EMI suppression capability; limited dynamic rail control; requires external non-volatile storage for settings	Prefer for cost-sensitive ADAS camera modules where 2MHz switching and on-chip OTP are non-critical.

Compared with FS26 and ISL78600, MPQ7930GUTE-0000-AEC1-Z uniquely combines six independently configurable bucks, 2MHz spread-spectrum operation, and on-chip MOTP memory-enabling fewer external components, tighter EMI control, and zero-external-storage configuration persistence in space-constrained ADAS domain controllers.

FAQ

What is the purpose of the MOTP memory in the MPQ7930?

The multi-page one-time programmable (MOTP) memory stores critical configuration data-including default VOUT values, soft-start slew rates, sequencing order, and PMBus addresses-persisting across power cycles without external EEPROM. Once programmed, settings remain immutable, ensuring deterministic boot behavior required for ISO 26262-compliant systems.

How does the MPQ7930 achieve EMI reduction without sacrificing transient response?

It uses frequency spread spectrum (FSS) modulation-shifting the 2MHz switching frequency by ±15% at 9kHz-smearing energy across a wider band to lower peak emissions. Because modulation depth and rate are carefully tuned, control-loop bandwidth remains unaffected, preserving <5µs load-step response time and <1% output deviation.

Can the six buck converters operate simultaneously at full rated current?

No. Thermal limits constrain simultaneous full-load operation: at 25°C ambient, maximum total continuous power dissipation is 6.16W (θJA = 31.7°C/W). Simultaneous 4A+4A+3A+3A+1A+1A exceeds safe junction temperature; derating or staggered activation is required per thermal simulation using θJC = 2.6°C/W (case-to-ambient on standard EVB).

What is the function of the "wettable flank" in the TQFN-32 package?

The wettable flank provides vertical sidewall plating on all perimeter leads, enabling automated optical inspection (AOI) of solder joint fillets during reflow. This improves process yield and field-reliability verification for automotive PCBs-especially critical for safety-critical ADAS modules where void-free solder joints are mandated by IPC-A-610 Class 3 standards.

Does the MPQ7930 support hardware-based power-on reset sequencing?

Yes. Six independent ENx pins allow asynchronous assertion/deassertion with programmable delays (0–7750 µs) via MOTP registers. Each ENx has internal hysteresis (100mV) and pull-down resistors (1.05–1.95MΩ), enabling robust, glitch-immune sequencing without external RC networks or dedicated supervisor ICs.

How is over-current protection implemented across different buck channels?

OCP uses valley-current limiting with hiccup mode: when ILIM_LS threshold is exceeded (e.g., 3–5.1A for Buck 1–2), the channel shuts down for 2–8ms before retrying. Peak-current limit (4–11A) provides fast short-circuit protection. Both thresholds are factory-trimmed and stored in MOTP, eliminating external sense resistors.

Is the PMBus interface compatible with standard system management bus (SMBus) controllers?

Yes. The MPQ7930 implements PMBus v1.3 over SMBus physical layer (open-drain SCL/SDA, 1000 kHz max clock), supporting all mandatory commands (READ_VIN, READ_VOUT, CLEAR_FAULTS) and optional ones (STORE_DEFAULT_ALL, CAPABILITY). Packet Error Checking (PEC) ensures CRC-8 integrity for all transactions.
