STMicroelectronics EVSPIN32G4 Demonstration Board

STMicroelectronics EVSPIN32G4 Demonstration Board is based on the STSPIN32G4 system in a package and STL110N10F7 power MOSFETs. The STSPIN32G4 integrates into a 9x9mm VFQFPN package, a triple high-performance half-bridge gate driver with a rich set of programmable features, and one mixed-signal STM32G431 microcontroller. The integrated operational amplifiers for current sensing, the drain-source voltage sensing of each power MOSFET, and comparators for overcurrent protection make it a fully integrated solution for motor control.

Thanks to the integrated voltage regulators, both the gate driver and control logic supplies can be generated starting from the motor supply without dedicated circuitry. The board ensures a full evaluation of the STSPIN32G4 and is designed for driving three-phase brushless DC motors. It also provides an easy-to-use solution for STSPIN32G4 evaluation in different applications such as power tools, e-Bikes, fans, and home appliances. The board can be configured in three-shunt or single-shunt, supporting both sensorless and sensor-based control algorithms.

The Arduino connector enables the STMicroelectronics EVSPIN32G4 to be interfaced with expansion boards, such as MEMS sensors or Bluetooth transceivers, while predisposition for CAN bus allows interconnection with master or slave modules to build complex motion control systems. The onboard ST-LINK/V2 programmer speeds up and simplifies the debugging of microcontroller firmware.
