Infineon CoolGaN™ Transistors & GaN-Based Solutions

Tailored to every humanoid robot functional block

Humanoid robots are emerging as game-changing tools across industries, from manufacturing environments to assisting healthcare professionals in patient care. As deployment expands across multiple segments, these systems require highly accurate and reliable power solutions. A single humanoid robot can include more than 70 joints and up to 600 power switches, making the selection of the right power semiconductor technology critical.

Infineon enables the key functional blocks in humanoid robots with a broad portfolio of dedicated solutions, including Power MOSFETs, GaN-based technologies, microcontrollers, sensors, memory, and connectivity, helping engineers design efficient, intelligent, and highly responsive robotic systems.

Why CoolGaN™ and Power MOSFETs for Humanoid Robots?

Infineon’s CoolGaN™ solutions and advanced Power MOSFETs deliver high-performance motor control for humanoid robots, cobots, and other robotics applications. These technologies provide system-level advantages across four key areas:

  • Small and Light: Higher switching efficiency reduces power losses, enabling smaller passive components and reduced heatsink size for space-constrained robotic joints.
  • Cool: Reduced switching and conduction losses minimize heat generation, enabling higher power density or lower operating temperatures for touch-sensitive designs.
  • Fast and Accurate: High-speed switching supports fast motor response and highly precise motion control essential for humanoid robotics.
  • Highly Efficient: Optimized switching performance increases overall system efficiency and extends battery life in mobile and autonomous platforms.

Robotic Solutions Portfolio

  • Power MOSFETs & CoolGaN™
  • Microcontrollers (XMC™, PSoC™, AURIX™)
  • Precision Magnetic Sensors
  • High-reliability Memory Solutions
  • Secure Connectivity (Wi-Fi, Bluetooth)
