EPC adds compact 3-phase BLDC motor drive inverter
EPC has introduced a 23mm 3-phase BLDC reference design inverter for small motor drives in humanoid wrists and hands and for drones.
The EPC91132 incorporates the EPC33110 GaN module, which is based on EPC GaN monolithic integrated circuit technology. The EPC33110 has three half bridges, gate drivers, bootstrap circuitry and level shifters in a small 6 mm x 6.5 mm QFN package. The module can be powered by a single 5V power supply up to 80V with typical on-resistance of 11.7mΩ and supporting 3.3V or 5V logic inputs.
The board has been designed with a flexible breakout-ring concept to support various form factors. With the outer ring removed, the board is 23 mm in diameter, which means it could be incorporated into small drone motors such as the Vertiq 23-06 platform.
“The next generation of humanoid robots and drones requires motor drives that combine extreme compactness with exceptional efficiency,” said Marco Palma, VPmMotor drive marketing and system engineering, EPC.”The EPC91132 demonstrates how monolithic GaN integration can simplify inverter design while delivering the switching speed, power density, and thermal performance required for next-generation motion systems.”
