With the rapid evolution of autonomous driving and smart cockpit technologies, the requirements for core power supplies in automotive SoCs have shifted from “stable power delivery” to “high performance, high integration, and high functional safety.” The MPQ2967, launched by MPS, is an automotive-grade dual-rail, digital multi-phase PWM controller designed specifically to address this trend and provide core power supply for autonomous driving SoCs. Mingjiada Electronics currently offers a long-term supply of genuine, in-stock MPQ2967 units and provides procurement and inventory buyback services for EMS manufacturers and end customers.
Product Positioning: The Power Control Core for Autonomous Driving SoCs
The MPQ2967 (full model number MPQ2967GQKTE) is a dual-rail, digital 4-phase controller with a PMBus interface. It is AEC-Q100 Grade 1 certified and developed in accordance with the ISO 26262 functional safety standard. This device can be used in conjunction with MPS Intelli-Phase™ DrMOS power stage products (such as the MPQ86960-AEC1) to build a complete multi-phase voltage regulator (VR) solution with minimal external components, offering significant advantages in space-constrained applications such as ADAS domain controllers and ECUs.
MPQ2967 Key Features
Fully digital architecture and flexible configuration. The MPQ2967 employs digital control and features an I²C-compatible system interface; both device configuration and fault parameters can be flexibly configured and monitored in real time via the PMBus interface. PMBus communication supports Packet Error Checking (PEC), effectively ensuring data transmission reliability. The chip incorporates Multi-Time Programmable (MTP) memory, which supports the storage and restoration of custom configurations and can be reprogrammed up to 1,000 times, facilitating flexible adaptation during development, debugging, and mass production.
Fast Transient Response and Automatic Loop Compensation. Based on MPS’s digital multiphase nonlinear control technology, the MPQ2967 achieves fast transient response to load steps with minimal output capacitance. Steady-state and load transient conditions share the same power loop control method; combined with automatic loop compensation, this significantly simplifies power loop configuration and shortens the design cycle. This controller employs ACOT PWM (ACP™) technology, further reducing output capacitance requirements and delivering predictable EMI performance.
High Efficiency and Intelligent Phase Shutdown. The device integrates Automatic Phase Shutdown (APS) functionality with or without Discontinuous Conduction Mode (DCM), automatically reducing the number of active phases under light load conditions to significantly improve overall efficiency. Active phase-to-phase current balancing technology ensures uniform current distribution across phases, reducing thermal stress and extending system lifespan.
Comprehensive monitoring and multiple protection features. The MPQ2967 provides comprehensive monitoring capabilities for input voltage (VIN), output voltage (VOUT), output current (IOUT), and regulator temperature; current monitoring is achieved through the current sampling (CS) output of Intelli-Phase™ products. Protection mechanisms include under-voltage lockout (UVLO), over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), over-temperature protection (OTP), and reverse voltage protection (RVP). It also features programmable short-circuit protection and open-circuit/short-circuit load detection, establishing a reliable safety barrier for autonomous driving systems. Each voltage rail is equipped with an independent enable pin (EN), supporting flexible power-up sequencing control.
Compact packaging and automotive-grade reliability. The MPQ2967 is housed in a TQFN-40 (6 mm × 6 mm) package, with an optional wettable flank (WF) QFN variant that facilitates visual inspection of solder joints and meets the stringent reliability requirements of automotive manufacturing.
Typical Applications
The MPQ2967 is ideally suited for automotive computing platforms with high demands for functional safety and power density:
Autonomous Driving (ADAS) SoC Core Power Supply: Provides multi-phase core voltages for high-performance SoCs, CPUs, GPUs, and FPGAs in ADAS domain controllers, serving as a proven design option for ADAS platforms.
In-Vehicle Infotainment and Smart Cockpits: Meets the multi-phase power supply requirements of high-computing-power cockpit chips.
ADAS Domain Controllers and ECUs: Serves as the core power management device for electronic control units.
AI Humanoid Robots and High-Performance Computing Platforms: When paired with the MPQ86750 Intelli-Phase™ solution, it provides highly efficient power management for AI humanoid robot SoC platforms and high-performance automotive computing platforms.
In a typical multi-phase parallel power supply architecture, MPS recommends pairing two MPQ2967 controllers with eight MPQ86960 (50A) DrMOS devices to achieve excellent dynamic load regulation control.
