Description

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.

  • All features

    • Power stage based on the STL60N10F7 power MOSFETs with output current up to 5 Arms and protected to overcurrent condition
    • Bus voltage from 10 V to 48 V with dedicated monitoring
    • STSPIN32G4, high performance three-phase motor controller with embedded STSPIN32G431 MCU
    • Triple-shunt or single-shunt differential current sensing using embedded operational amplifiers
    • Inputs for speed/position feedback by digital Hall sensors or incremental quadrature endcoders
    • Predisposition for CAN bus
    • NTC sensor for power stage temperature monitoring
    • Interface with STWIN.box and external sensor boards
