The EPC91132 reference design integrates GaN power stage, sensing, protection, and feedback for robotic and drone motor drives.
The next-generation humanoid robots and drones need motor drives to move closer to the actuator and share space with mechanical structures and sensors. They still have to deliver high current, fast control response, and reliable protection.
EPC91132 addresses this integration problem with a compact three-phase BLDC motor-drive inverter reference design based on the EPC33110 GaN three-phase module. Its core inverter can be reduced to a 23-mm diameter form factor. The company reports 11 ARMS continuous current per phase for humanoid robotic joint applications at 48 V and switching frequencies up to 100 kHz.
