Description

This reference design features TI Sitara™ MCU-AM261x devices handling an industrial Ethernet-connected motor drive. The design uses a 70mm diameter printed circuit board (PCB) to drive a humanoid robot joint (48V, 1kW Eyoubot motor). The design demonstrates a small form factor and simplified integrated platform. The platform includes a high-power density power stage using three DRV7167 half bridges GaN-FET, an accurate real-time control stage using AM2612 500MHz R5F core MCU and AMC0106 functionally isolated delta-sigma modulator, also high bandwidth communication operates with industrial Ethernet. This design passed all functional tests. System testing is in progress. The software and full design guide become available soon.
