STMicroelectronics EVLSPIN32G4-ACT Reference Board

STMicroelectronics EVLSPIN32G4-ACT Reference Board is a reference design for implementing next-generation smart actuators based on the STSPIN32G4 Motor Controller. The 9mm x 9mm VFQFPN packaged STSPIN32G4 integrates a triple high-performance half-bridge gate driver with a rich set of programmable features and a mixed signal STM32G431 microcontroller. The board is designed to drive three-phase brushless motors up to 5ARMS output current and 48V supply input, delivering a total power of 250W in a very compact form factor (62mm x 50mm). Monitoring is available for the power stage in case of overheating, overvoltage, and overcurrent. The sensing of motor winding currents can be selected between three-shunt or single-shunt topologies. The board is ready for FOC and 6-step control algorithms and can run in sensor-less and sensor-based modes using Hall sensors or a quadrature encoder.

Thanks to a smooth interfacing with STWIN.box development kit and a complete software and firmware ecosystem, the motor inverter is empowered by wired and wireless connectivity (RS485, UART, USB, CAN, and BLUETOOTH® Low Energy, Wi-Fi®, and NFC), a plethora of inertial end environmental sensors (accelerometer, gyroscope, inclinometer, magnetometer, humidity, temperature, and pressure), and onboard data storage (microSD™ card). EVLSPIN32G4-ACT is perfect for cutting-edge motor control solutions such as IoT, condition monitoring, and predictive maintenance.
