STMicroelectronics’ EVSPIN32G4-dual demonstration board controls two motors from a single STSPIN32G4 integrated driver. The STSPIN32G4 motor controller contains an Arm Cortex-M4 microcontroller with the processing power to manage both motors simultaneously, executing complex algorithms like field-oriented control in real-time. In addition, MCU peripherals support sensored or sensorless FOC and advanced position and torque-control algorithms. The demonstration board leverages an advanced three-phase gate driver integrated in the STSPIN32G4 and an additional STDRIVE101 gate driver to control two three-phase inverters delivering up to 10A with a maximum supply voltage of 74V. Both gate drivers have their own bootstrap circuitry and safety features including drain-source voltage monitoring, cross-conduction prevention, several thermal protection mechanisms and under-voltage lockout.
