Description

The 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 up to 5 Arms output

current and 48 V supply input delivering a 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.

Thanks to a smooth interfacing with the 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,

NFC), a plethora of inertial end environmental sensors (accelerometer, gyroscope,

inclinometer, magnetometer, humidity, temperature, pressure), and data storage

onboard (microSD™ card) making the EVLSPIN32G4-ACT a perfect suit for cutting

edge motor control solutions such as IoT, condition monitoring, and predictive

maintenance.
