EVLDRIVE101-HPD Circular and extremely compact motor control reference design for high-current brushless motors based on STDRIVE

The EVLDRIVE101-HPD is a three-phase extremely compact inverter for brushless motors based on the STDRIVE101 device in conjunction with the STM32G071KB microcontroller. It can be used with an extremely wide variety of driving techniques, with FOC and trapezoidal control, sensored and sensor-less. The board is a ready-to-use and flexible solution ideal for battery-powered three-phase applications requiring high output currents. The EVLDRIVE101-HPD embeds a fast power-on circuit that connects/disconnects the battery, significantly extending its duration. The low Rds(on) STL220N6F7 MOSFETs allow operation at very high load current up to 750 W. The whole design is done in a compact circular layout of 50 mm diameter.

Debug support and programming capability are possible thanks to the provided SWD interface and the direct firmware update is also available.
