Compact 48 V Motor Control Solution for Humanoid Robotics — Coming Soon!

The REF_HUMA_MTR_48V_25A from Infineon Technologies is a compact 3-phase motor inverter reference board engineered specifically for humanoid robot joint applications. Featuring a round form factor measuring 65 mm in diameter and 15 mm in height, the platform is designed for seamless integration inside robotic joints where space, efficiency, and performance are critical. Built around the Infineon integrated 100 V GaN (iGaN) intelligent power stage, the reference solution targets motor drive applications operating from a 48 V bus voltage and supporting up to 25 A_RMS output current. The platform delivers up to 98% efficiency, helping designers reduce power losses and thermal challenges while maximizing operating performance.

The board incorporates the PSC3M5FDS2LHQ1 microcontroller and supports a broad range of industrial communication interfaces, including CAN-FD, RS-485, SPI, UART, and I²C, providing flexibility for advanced robotic control architectures. Operating at a 100 kHz switching frequency, the system enables precise motor control while maintaining high power density. Developed as a system reference solution, REF_HUMA_MTR_48V_25A enables developers of humanoid robots to accelerate design cycles by leveraging a proven motor-control platform that combines Infineon's power, sensing, control, and connectivity technologies. The board showcases how advanced GaN-based motor drives can achieve compact size, high efficiency, and robust performance in next-generation robotic systems.

Note: Only the first two applications are explicitly stated by Infineon. The remaining applications are reasonable use cases for a humanoid robotic motor inverter reference platform but are not specifically listed by the manufacturer.
