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 section using three DRV7167 half- bridge GaN motor driver power stages, an accurate real-time control stage with an AM2612 500MHz R5F core MCU and AMC0106 functionally isolated delta- sigma modulator, plus high-bandwidth communication through industrial Ethernet.
Features
- Compact design with highly integrated ICs facilitating a 70mm diameter PCB and a 15mm diameter through hole
- Supports multiprotocol industrial Ethernet communication and multiprotocol encoder interface
- Small form factor DRV7167 half-bridge GaN motor driver power stage
- Precision phase current sense using 1mΩ shunt and the AMC0106M05 functional isolated modulator
