EPC Introduces Smallest GaN Drive Based on EPC33110 for Robots and DronesEPC Introduces Smallest GaN Drive Based on EPC33110 for Robots and Drones

Efficient Power Conversion introduced the EPC91132, a compact 3-phase BLDC motor drive inverter reference design based on the EPC33110 GaN three-phase module. The EPC91132 is a 23 mm reference design inverter for small motor drives for 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.

Next generation humanoid robots and drones require lighter, smaller and more efficient power electronics. GaN technology is a good candidate for motor drive systems to operate at switching frequencies above 100 kHz while minimizing conduction and switching losses. The capabilities improve efficiency, dynamic response and control bandwidth, reduce size of passive components and overall volume (more info).
