The design is based on the STSPIN32F0B controller and STL180N6F7 (or STL220N6F7) power MOSFET. The board is ready for sensorless and sensored FOC, and can be configured for six-step sensorless control through available BEMF sensing circuitry. The firmware example included in STM32 Motor Control SDK (X-CUBE-MCSDK-Y) uses position feedback from Hall effect sensors, with debugging and programming capability available through the SWD interface and the direct firmware update feature. The board can deliver up to 15 A continuous current, thanks also to the optimal thermal dissipation provided by an embedded heatsink. It embeds a fast power-on circuit that connects and disconnects the battery, allowing standby consumption below 1 μA for extended battery duration. Several protection features are included, such as thermal shutdown, undervoltage lockout, overcurrent protection with programmable threshold and reverse biasing of power stage outputs. This reference design is predominately intended for power tools, but is very suitable for any battery-powered application involving similar architecture, rating and performance. A potentiometer input for speed variation is available.
