The STSPIN32G4 integrates in a 9x9 mm 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 and 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 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 on-board ST-LINK/V2 programmer speeds up and simplifies the debugging of microcontroller firmware. DB4420 - Rev 1 page 2/18 EVSPIN32G4, EVSPIN32G4NH Specifications 1 Specifications Table 1.

Not provided with EVSPIN32G4NH DB4420 - Rev 1 page 12/18 EVSPIN32G4, EVSPIN32G4NH Waste and recycling 2 Waste and recycling The evaluation board is not to be disposed of as urban waste. At the end of its life cycle, differentiated waste collection must be followed. Consult the local authorities for more information on the proper disposal channels and recycling centers. It is mandatory to collect separately the evaluation board and make sure it is delivered to the appropriate waste management and recycling centers. As of 15 August 2018, in all countries belonging to the European Union, the evaluation board is subject to the requirements of WEEE Directive 2012/19/EU, and therefore it is forbidden to dispose of the evaluation board as undifferentiated waste or with other domestic waste. Incorrect disposal of the evaluation board may cause damage to the environment and may incur fines based on specific countries’ rules, regulations, and laws.
