This use case examines the application of the MPQ86750 and MPQ2967 in artificial intelligence (AI) humanoid robotics.

The MPQ86750 Intelli-Phase^TM solution combined with the MPQ2967 provides high-efficiency power management for AI humanoid robotics system-on-chip (SoC) platforms, achieving improved reliability, compact size, and simplified design.

AI humanoid robots mimic human-like movements and interactions, with complex functions including decision-making based on sensor data, manipulating objects, navigating physical environments, and adapting using machine learning algorithms. These functions are based on advanced AI algorithms that require substantial computational power. As a result, AI humanoid robotics designers must prioritize thermal and power consumption management to prevent safety risks, damage to components, and reduced system reliability.

The MPQ86750 Intelli-Phase^TM solution combined with the MPQ2967 provides high-efficiency power management for AI humanoid robotics system-on-chip (SoC) platforms, achieving improved reliability, compact size, and simplified design.

The MPQ86750 is a monolithic, half-bridge Intelli-Phase^TM solution with built-in, internal power MOSFETs and gate drivers. The integrated MOSFETs and gate drivers achieve high efficiency through an optimized dead time (DT) and reduced parasitic inductance. The MPQ86750 is available in an LGA-38 (5mmx6mm) package.

Additional features of the MPQ86750 include:

• Wide Operating Input Voltage (V_IN) Range
• 50A of Output Current (I_OUT)
• Accepts Tri-State Pulse-Width Modulation (PWM) Signal
• Built-In Switch for Bootstrap (BST)
• Accu-Sense^TM Current Sense
• Temperature Sense
• Current-Limit Protection and Fault Flag
• Over-Temperature Protection (OTP) and Fault Flag
• Catastrophic Protection and Fault Flag
• Used for Multi-Phase Operation
• Available in AEC-Q100 Grade 1
• MPSafe^TM QM: Developed for Functional Safety (Applications: ISO 26262 Compliant)

The MPQ2967 is a digital, dual-rail, multi-phase controller that can work with the MPQ86750 to complete a multi-phase voltage regulator (VR) solution with minimal external components. It provides temperature monitoring and various protections, including 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). The MPQ2967 is available in a TQFN-40 (6mmx6mm) package.

Additional features of the MPQ2967 include:

• Dual-Rail, Up to 4-Phase Digital Pulse-Width Modulation (PWM) Controller
• PMBus Compliant for Configurations and Monitoring
• PWM-VID Interface Compliant
• Built-In Multiple-Time Programmable (MTP) Memory to Store Custom Configurations
• Automatic Loop Compensation
• Automatic Phase-Shedding (APS) with and without Discontinuous Conduction Mode (DCM) to Improve Overall Efficiency
• Phase-to-Phase Active Current Balancing
• Input Voltage (V_IN) and Output Voltage (V_OUT) Monitoring
• Output Current (I_OUT) Monitoring
• Cyclic Redundancy Check (CRC) and Error Correction Code (ECC) for MTP Transformation
• Packet Error Checking (PEC) for PMBus Communication
• Separate EN for Each Rail
• Digital, Configurable Load Line
• Available in AEC-Q100 Grade 1
