EVLSPIN32G4-ACT

EVLSPIN32G4-ACT is a reference design for implementing next generation smart actuators, based on the STSPIN32G4, a system-in-package integrating in a 9x9 mm VFQFPN package, 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 with total power of 250 W in a very compact form factor (62 mm x 50 mm). 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 topology. The board is ready for FOC and 6-step control algorithms and can run in sensor-less and sensor-based mode using Hall sensors or quadrature encoder.
